4. CLINICAL PARTICULARS

4.1 Therapeutic indications

Jentadueto is indicated in adults with type 2 diabetes mellitus as an adjunct to diet and exercise to 
improve glycaemic control:

• in patients inadequately controlled on their maximally tolerated dose of metformin alone 

• in combination with other medicinal products for the treatment of diabetes, including insulin, in 
patients inadequately controlled with metformin and these medicinal products

• in patients already being treated with the combination of linagliptin and metformin as separate 
tablets.

(see sections 4.4, 4.5 and 5.1 for available data on different combinations).

4.2 Posology and method of administration

Posology
Adults with normal renal function (GFR ≥90 ml/min)
The dose of antihyperglycaemic therapy with Jentadueto should be individualised on the basis of the 
patient’s current regimen, effectiveness, and tolerability, while not exceeding the maximum 
recommended daily dose of 5 mg linagliptin plus 2,000 mg of metformin hydrochloride.

Patients inadequately controlled on maximal tolerated dose of metformin monotherapy 
For patients not adequately controlled on metformin alone, the usual starting dose of Jentadueto
should provide linagliptin dosed as 2.5 mg twice daily (5 mg total daily dose) plus the dose of 
metformin already being taken.



3

Patients switching from co-administration of linagliptin and metformin
For patients switching from co-administration of linagliptin and metformin, Jentadueto should be 
initiated at the dose of linagliptin and metformin already being taken.

Patients inadequately controlled on dual combination therapy with the maximal tolerated dose of
metformin and a sulphonylurea
The dose of Jentadueto should provide linagliptin dosed as 2.5 mg twice daily (5 mg total daily dose) 
and a dose of metformin similar to the dose already being taken. When linagliptin plus metformin 
hydrochloride is used in combination with a sulphonylurea, a lower dose of the sulphonylurea may be 
required to reduce the risk of hypoglycaemia (see section 4.4).

Patients inadequately controlled on dual combination therapy with insulin and the maximal tolerated 
dose of metformin
The dose of Jentadueto should provide linagliptin dosed as 2.5 mg twice daily (5 mg total daily dose) 
and a dose of metformin similar to the dose already being taken. When linagliptin plus metformin 
hydrochloride is used in combination with insulin, a lower dose of insulin may be required to reduce 
the risk of hypoglycaemia (see section 4.4).

For the different doses of metformin, Jentadueto is available in strengths of 2.5 mg linagliptin plus
850 mg metformin hydrochloride and 2.5 mg linagliptin plus 1,000 mg metformin hydrochloride. 

Special populations
Elderly
As metformin is excreted by the kidney, Jentadueto should be used with caution as age increases.
Monitoring of renal function is necessary to aid in prevention of metformin-associated lactic acidosis, 
particularly in the elderly (see sections 4.3 and 4.4).

Renal impairment
A GFR should be assessed before initiation of treatment with metformin containing products and at 
least annually thereafter. In patients at an increased risk of further progression of renal impairment and 
in the elderly, renal function should be assessed more frequently, e.g. every 3-6 months.
Factors that may increase the risk of lactic acidosis (see 4.4) should be reviewed before considering 
initiation of metformin in patients with GFR<60 ml/min.
If no adequate strength of Jentadueto is available, individual monocomponents should be used instead 
of the fixed dose combination.

Hepatic impairment
Jentadueto is not recommended in patients with hepatic impairment due to the active substance 
metformin (see sections 4.3 and 5.2). Clinical experience with Jentadueto in patients with hepatic 
impairment is lacking.

Paediatric population
The safety and efficacy of Jentadueto in children and adolescents aged 0 to 18 years have not been 
established. No data are available. 

Method of administration
Jentadueto should be taken twice daily with meals to reduce the gastrointestinal adverse reactions
associated with metformin.
All patients should continue their diet with an adequate distribution of carbohydrate intake during the 
day. Overweight patients should continue their energy-restricted diet.

If a dose is missed, it should be taken as soon as the patient remembers. However, a double dose 
should not be taken at the same time. In that case, the missed dose should be skipped. 

4.3 Contraindications

• Hypersensitivity to the active substances or to any of the excipients listed in section 6.1.
• Any type of acute metabolic acidosis (such as lactic acidosis, diabetic ketoacidosis)
• Diabetic pre-coma.
• Severe renal failure (GFR <30 ml/min).
• Acute conditions with the potential to alter renal function such as: dehydration, severe infection, 

shock.
• Disease which may cause tissue hypoxia (especially acute disease, or worsening of chronic 

disease) such as: decompensated heart failure, respiratory failure, recent myocardial infarction, 
shock.

• Hepatic impairment, acute alcohol intoxication, alcoholism (see section 4.5).

4.4 Special warnings and precautions for use

General
Jentadueto should not be used in patients with type 1 diabetes.



5

Hypoglycaemia
When linagliptin was added to a sulphonylurea on a background of metformin, the incidence of 
hypoglycaemia was increased over that of placebo.

Sulphonylureas and insulin are known to cause hypoglycaemia. Therefore, caution is advised when 
Jentadueto is used in combination with a sulphonylurea and/or insulin. A dose reduction of the 
sulphonylurea or insulin may be considered (see section 4.2).

Hypoglycaemia is not identified as adverse reaction for linagliptin, metformin, or linagliptin plus 
metformin. In clinical trials, the incidence rates of hypoglycemia were comparably low in patients 
taking linagliptin in combination with metformin or metformin alone.

Lactic acidosis
Lactic acidosis, a very rare but serious metabolic complication, most often occurs at acute worsening 
of renal function or cardiorespiratory illness or sepsis. Metformin accumulation occurs at acute 
worsening of renal function and increases the risk of lactic acidosis.

In case of dehydration (severe diarrhoea or vomiting, fever or reduced fluid intake), metformin should 
be temporarily discontinued and contact with a health care professional is recommended.

Medicinal products that can acutely impair renal function (such as antihypertensives, diuretics and 
NSAIDs) should be initiated with caution in metformin-treated patients. Other risk factors for lactic 
acidosis are excessive alcohol intake, hepatic impairment, inadequately controlled diabetes, ketosis, 
prolonged fasting and any conditions associated with hypoxia, as well as concomitant use of medicinal 
products that may cause lactic acidosis (see sections 4.3 and 4.5).

Patients and/or care-givers should be informed of the risk of lactic acidosis. Lactic acidosis is 
characterised by acidotic dyspnea, abdominal pain, muscle cramps, asthenia and hypothermia followed 
by coma. In case of suspected symptoms, the patient should stop taking metformin and seek 
immediate medical attention. Diagnostic laboratory findings are decreased blood pH (<7.35), 
increased plasma lactate levels (>5 mmol/l) and an increased anion gap and lactate/pyruvate ratio.

Administration of iodinated contrast agent
Intravascular administration of iodinated contrast agents may lead to contrast induced nephropathy, 
resulting in metformin accumulation and an increased risk of lactic acidosis. Metformin should be 
discontinued prior to or at the time of the imaging procedure and not restarted until at least 48 hours 
after, provided that renal function has been re-evaluated and found to be stable, see sections 4.2 and 
4.5.

Renal function
GFR should be assessed before treatment initiation and regularly thereafter, see section 4.2. Metformin 
is contraindicated in patients with GFR<30 ml/min and should be temporarily discontinued in the 
presence of conditions that alter renal function, see section 4.3).

Cardiac function
Patients with heart failure are more at risk of hypoxia and renal impairment. In patients with stable 
chronic heart failure, Jentadueto may be used with a regular monitoring of cardiac and renal function.
For patients with acute and unstable heart failure, Jentadueto is contraindicated (see section 4.3).

Surgery
Metformin must be discontinued at the time of surgery under general, spinal or epidural anesthesia. 
Therapy may be restarted no earlier than 48 hours following surgery or resumption of oral nutrition 
and provided that renal function has been re-evaluated and found to be stable.

Elderly
Caution should be exercised when treating patients 80 years and older (see section 4.2).



6

Change in clinical status of patients with previously controlled type 2 diabetes
As Jentadueto contains metformin, a patient with previously well controlled type 2 diabetes on 
Jentadueto who develops laboratory abnormalities or clinical illness (especially vague and poorly 
defined illness) should be evaluated promptly for evidence of ketoacidosis or lactic acidosis. 
Evaluation should include serum electrolytes and ketones, blood glucose and, if indicated, blood pH, 
lactate, pyruvate, and metformin levels. If acidosis of either form occurs, Jentadueto must be stopped 
immediately and other appropriate corrective measures initiated.

Acute pancreatitis
Use of DPP-4 inhibitors has been associated with a risk of developing acute pancreatitis. Acute 
pancreatitis has been observed in patients taking linagliptin. In a cardiovascular and renal safety study 
(CARMELINA) with median observation period of 2.2 years, adjudicated acute pancreatitis was 
reported in 0.3% of patients treated with linagliptin and in 0.1% of patients treated with placebo.
Patients should be informed of the characteristic symptoms of acute pancreatitis. If pancreatitis is 
suspected, Jentadueto should be discontinued; if acute pancreatitis is confirmed, Jentadueto should not 
be restarted. Caution should be exercised in patients with a history of pancreatitis.

Bullous pemphigoid
Bullous pemphigoid has been observed in patients taking linagliptin. In the CARMELINA study, 
bullous pemphigoid was reported in 0.2% of patients on treatment with linagliptin and in no patient on 
placebo. If bullous pemphigoid is suspected, Jentadueto should be discontinued.

4.5 Interaction with other medicinal products and other forms of interaction

No interaction studies have been performed. However, such studies have been conducted with the 
individual active substances, i.e. linagliptin and metformin. Co-administration of multiple doses of 
linagliptin and metformin did not meaningfully alter the pharmacokinetics of either linagliptin or 
metformin in healthy volunteers and patients. 

Linagliptin
In vitro assessment of interactions
Linagliptin is a weak competitive and a weak to moderate mechanism-based inhibitor of CYP isozyme 
CYP3A4, but does not inhibit other CYP isozymes. It is not an inducer of CYP isozymes.

Linagliptin is a P-glycoprotein substrate, and inhibits P-glycoprotein mediated transport of digoxin 
with low potency. Based on these results and in vivo drug interaction studies, linagliptin is considered 
unlikely to cause interactions with other P-gp substrates.

In vivo assessment of interactions
Effects of other medicinal products on linagliptin
Clinical data described below suggest that the risk for clinically meaningful interactions by 
coadministered medicinal products is low. 

Metformin:
Co-administration of multiple three-times-daily doses of 850 mg metformin hydrochloride with 10 mg 
linagliptin once daily did not clinical meaningfully alter the pharmacokinetics of linagliptin in healthy 
subjects. 

Sulphonylureas:
The steady-state pharmacokinetics of 5 mg linagliptin were not changed by concomitant 
administration of a single 1.75 mg dose glibenclamide (glyburide).



7

Ritonavir:
Co-administration of a single 5 mg oral dose of linagliptin and multiple 200 mg oral doses of ritonavir, 
a potent inhibitor of P-glycoprotein and CYP3A4, increased the AUC and Cmax of linagliptin 
approximately twofold and threefold, respectively. The unbound concentrations, which are usually less 
than 1% at the therapeutic dose of linagliptin, were increased 4-5-fold after co-administration with 
ritonavir. Simulations of steady-state plasma concentrations of linagliptin with and without ritonavir 
indicated that the increase in exposure will not be associated with an increased accumulation. These 
changes in linagliptin pharmacokinetics were not considered to be clinically relevant. Therefore, 
clinically relevant interactions would not be expected with other P-glycoprotein/CYP3A4 inhibitors.

Rifampicin:
Multiple co-administration of 5 mg linagliptin with rifampicin, a potent inductor of P-glycoprotein and 
CYP3A4, resulted in a 39.6% and 43.8% decreased linagliptin steady-state AUC and Cmax
respectively, and about 30% decreased DPP-4 inhibition at trough. Thus full efficacy of linagliptin in 
combination with strong P-gp inducers might not be achieved, particularly if these are administered 
long-term. Co-administration with other potent inducers of P-glycoprotein and CYP3A4, such as 
carbamazepine, phenobarbital and phenytoin has not been studied.

Effects of linagliptin on other medicinal products
In clinical studies, as described below, linagliptin had no clinically relevant effect on the 
pharmacokinetics of metformin, glyburide, simvastatin, warfarin, digoxin or oral contraceptives 
providing in vivo evidence of a low propensity for causing interactions with substrates of CYP3A4, 
CYP2C9, CYP2C8, P-glycoprotein, and organic cationic transporter (OCT).

Metformin:
Co-administration of multiple daily doses of 10 mg linagliptin with 850 mg metformin hydrochloride, 
an OCT substrate, had no relevant effect on the pharmacokinetics of metformin in healthy subjects. 
Therefore, linagliptin is not an inhibitor of OCT-mediated transport.

Sulphonylureas:
Co-administration of multiple oral doses of 5 mg linagliptin and a single oral dose of 1.75 mg 
glibenclamide (glyburide) resulted in clinically not relevant reduction of 14% of both AUC and Cmax
of glibenclamide. Because glibenclamide is primarily metabolised by CYP2C9, these data also support 
the conclusion that linagliptin is not a CYP2C9 inhibitor. Clinically meaningful interactions would not 
be expected with other sulphonylureas (e.g., glipizide, tolbutamide, and glimepiride) which, like 
glibenclamide, are primarily eliminated by CYP2C9. 

Digoxin:
Co-administration of multiple daily doses of 5 mg linagliptin with multiple doses of 0.25 mg digoxin 
had no effect on the pharmacokinetics of digoxin in healthy subjects. Therefore, linagliptin is not an 
inhibitor of P-glycoprotein-mediated transport in vivo.

Warfarin:
Multiple daily doses of 5 mg linagliptin did not alter the pharmacokinetics of S(-) or R(+) warfarin, a 
CYP2C9 substrate, administered in a single dose.

Simvastatin:
Multiple daily doses of linagliptin had a minimal effect on the steady-state pharmacokinetics of 
simvastatin, a sensitive CYP3A4 substrate, in healthy subjects. Following administration of a 
supratherapeutic dose of 10 mg linagliptin concomitantly with 40 mg of simvastatin daily for 6 days, 
the plasma AUC of simvastatin was increased by 34%, and the plasma Cmax by 10%.

Oral contraceptives:
Co-administration with 5 mg linagliptin did not alter the steady-state pharmacokinetics of 
levonorgestrel or ethinylestradiol.



8

Metformin
Combination requiring precautions for use
Glucocorticoids (given by systemic and local routes), beta-2-agonists, and diuretics have intrinsic 
hyperglycaemic activity. The patient should be informed and more frequent blood glucose monitoring 
performed, especially at the beginning of treatment with such medicinal products. If necessary, the 
dose of the anti-hyperglycaemic medicinal product should be adjusted during therapy with the other 
medicinal product and on its discontinuation.

Some medicinal products can adversely affect renal function which may increase the risk of lactic 
acidosis, e.g. NSAIDs, including selective cyclo-oxygenase (COX) II inhibitors, ACE inhibitors, 
angiotensin II receptor antagonists and diuretics, especially loop diuretics. When starting or using such 
products in combination with metformin, close monitoring of renal function is necessary.

Organic cation transporters (OCT)
Metformin is a substrate of both transporters OCT1 and OCT2. Co-administration of metformin with
• Inhibitors of OCT1 (such as verapamil) may reduce efficacy of metformin.
• Inducers of OCT1 (such as rifampicin) may increase gastrointestinal absorption and efficacy of 

metformin.
• Inhibitors of OCT2 (such as cimetidine, dolutegravir, ranolazine, trimethoprime, vandetanib, 

isavuconazole) may decrease the renal elimination of metformin and thus lead to an increase in 
metformin plasma concentration.

• Inhibitors of both OCT1 and OCT2 (such as crizotinib, olaparib) may alter efficacy and renal 
elimination of metformin.

Caution is therefore advised, especially in patients with renal impairment, when these drugs are 
coadministered with metformin, as metformin plasma concentration may increase. If needed, dose 
adjustment of metformin may be considered as OCT inhibitors/inducers may alter the efficacy of 
metformin.

Concomitant use not recommended
Alcohol
Alcohol intoxication is associated with an increased risk of lactic acidosis, particularly in cases of 
fasting, malnutrition or hepatic impairment. 

Iodinated contrast agents
Jentadueto must be discontinued prior to or at the time of the imaging procedure and not restarted until 
at least 48 hours after, provided that renal function has been re-evaluated and found to be stable, see
sections 4.2 and 4.4. 

4.6 Fertility, pregnancy and lactation

Pregnancy
The use of linagliptin has not been studied in pregnant women. Animal studies do not indicate direct 
or indirect harmful effects with respect to reproductive toxicity (see section 5.3). 
A limited amount of data suggests that the use of metformin in pregnant women is not associated with 
an increased risk of congenital malformations. Animal studies with metformin do not indicate harmful 
effects with respect to reproductive toxicity (see section 5.3).
Non-clinical reproduction studies did not indicate an additive teratogenic effect attributed to the co-
administration of linagliptin and metformin.
Jentadueto should not be used during pregnancy. If the patient plans to become pregnant, or if 
pregnancy occurs, treatment with Jentadueto should be discontinued and switched to insulin treatment 
as soon as possible in order to lower the risk of foetal malformations associated with abnormal blood 
glucose levels.

Breast-feeding
Studies in animals have shown excretion of both metformin and linagliptin into milk in lactating rats. 
Metformin is excreted in human milk in small amounts. It is not known whether linagliptin is excreted 



9

into human milk. A decision must be made whether to discontinue breast-feeding or to 
discontinue/abstain from Jentadueto therapy taking into account the benefit of breast-feeding for the 
child and the benefit of therapy for the woman.

Fertility
The effect of Jentadueto on human fertility has not been studied. No adverse effects of linagliptin on 
fertility were observed in male or female rats (see section 5.3).

4.7 Effects on ability to drive and use machines

Jentadueto has no or negligible influence on the ability to drive and use machines. However, patients 
should be alerted to the risk of hypoglycaemia when Jentadueto is used in combination with other anti-
diabetic medicinal products known to cause hypoglycaemia (e.g. sulphonylureas).

4.8 Undesirable effects

Summary of the safety profile
The safety of linagliptin 2.5 mg twice daily (or its bioequivalent of 5 mg once daily) in combination 
with metformin has been evaluated in over 6800 patients with type 2 diabetes mellitus. In placebo-
controlled studies, more than 1800 patients were treated with the therapeutic dose of either 2.5 mg 
linagliptin twice daily (or its bioequivalent of 5 mg linagliptin once daily) in combination with 
metformin for ≥ 12/24 weeks.

In the pooled analysis of the seven placebo-controlled trials, the overall incidence of adverse events in 
patients treated with placebo and metformin was comparable to that seen with linagliptin 2.5 mg and 
metformin (54.3 and 49.0%). Discontinuation of therapy due to adverse events was comparable in 
patients who received placebo and metformin to patients treated with linagliptin and metformin (3.8% 
and 2.9%).

The most frequently reported adverse reaction for linagliptin plus metformin was diarrhoea (1.6%) 
with a comparable rate on metformin plus placebo (2.4%).

Hypoglycaemia may occur when Jentadueto is administered together with sulphonylurea (≥ 1 case per 
10 patients).

Tabulated list of adverse reactions

Description of selected adverse reactions
Hypoglycaemia
In one study linagliptin was given as add-on to metformin plus sulphonylurea. When linagliptin and 
metformin were administered in combination with a sulphonylurea, hypoglycaemia was the most 
frequently reported adverse event (linagliptin plus metformin plus sulphonylurea 23.9% and 16.0% in 
placebo plus metformin plus sulphonylurea).

When linagliptin and metformin were administered in combination with insulin, hypoglycaemia was 
the most frequently reported adverse event, but occurred at comparable rate when placebo and 
metformin were combined with insulin (linagliptin plus metformin plus insulin 29.5% and 30.9% in 
the placebo plus metformin plus insulin group) with a low rate of severe (requiring assistance)
episodes (1.5% and 0.9%).

Other adverse reactions
Gastrointestinal disorders such as, nausea, vomiting, diarrhoea and decreased appetite and abdominal 
pain occur most frequently during initiation of therapy with Jentadueto or metformin hydrochloride 
and resolve spontaneously in most cases. For prevention, it is recommended that Jentadueto be taken 
during or after meals. A slow increase in dose of metformin hydrochloride may also improve 
gastrointestinal tolerability. 
Long-term treatment with metformin has been associated with a decrease in vitamin B12 absorption 
which may very rarely result in clinically significant vitamin B12 deficiency (e.g. megaloblastic 
anaemia).

Linagliptin cardiovascular and renal safety study (CARMELINA)
The CARMELINA study evaluated the cardiovascular and renal safety of linagliptin versus placebo in 
patients with type 2 diabetes and with increased CV risk evidenced by a history of established 
macrovascular or renal disease (see section 5.1). The study included 3494 patients treated with 
linagliptin (5 mg) and 3485 patients treated with placebo. Both treatments were added to standard of
care targeting regional standards for HbA1c and CV risk factors. The overall incidence of adverse 
events and serious adverse events in patients receiving linagliptin was similar to that in patients 
receiving placebo. Safety data from this study was in line with previous known safety profile of 
linagliptin.

In the treated population, severe hypoglycaemic events (requiring assistance) were reported in 3.0% of 
patients on linagliptin and in 3.1% on placebo. Among patients who were using sulfonylurea at 
baseline, the incidence of severe hypoglycaemia was 2.0% in linagliptin-treated patients and 1.7% in 
placebo treated patients. Among patients who were using insulin at baseline, the incidence of severe 
hypoglycaemia was 4.4% in linagliptin-treated patients and 4.9% in placebo treated patients.

In the overall study observation period adjudicated acute pancreatitis was reported in 0.3% of patients 
treated with linagliptin and in 0.1% of patients treated with placebo.

In the CARMELINA study, bullous pemphigoid was reported in 0.2% of patients treated with 
linagliptin and in no patient treated with placebo.

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It 
allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare 
professionals are asked to report any suspected adverse reactions via the national reporting system 
listed in Appendix V.

4.9 Overdose

Linagliptin
During controlled clinical trials in healthy subjects, single doses of up to 600 mg linagliptin 
(equivalent to 120 times the recommended dose) were not associated with a dose dependent increase 
in adverse events. There is no experience with doses above 600 mg in humans.

Metformin
Hypoglycaemia has not been seen with metformin hydrochloride doses of up to 85 g, although lactic 
acidosis has occurred in such circumstances. High overdose of metformin hydrochloride or 
concomitant risks may lead to lactic acidosis. Lactic acidosis is a medical emergency and must be 
treated in hospital. The most effective method to remove lactate and metformin hydrochloride is 
haemodialysis.

Management
In the event of an overdose, it is reasonable to employ the usual supportive measures, e.g. remove 
unabsorbed material from the gastrointestinal tract, employ clinical monitoring, and institute clinical 
measures if required.

5. PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Drugs used in diabetes, combinations of oral blood glucose lowering 
drugs, ATC code: A10BD11

Jentadueto combines two antihyperglycaemic medicinal products with complementary mechanisms of 
action to improve glycaemic control in patients with type 2 diabetes: linagliptin, a dipeptidyl peptidase 
4 (DPP-4) inhibitor, and metformin hydrochloride, a member of the biguanide class.

Linagliptin
Mechanism of action
Linagliptin is an inhibitor of the enzyme DPP-4 (Dipeptidyl peptidase 4) an enzyme which is involved 
in the inactivation of the incretin hormones GLP-1 and GIP (glucagon-like peptide-1, glucose-
dependent insulinotropic polypeptide). These hormones are rapidly degraded by the enzyme DPP-4. 
Both incretin hormones are involved in the physiological regulation of glucose homeostasis. Incretins 
are secreted at a low basal level throughout the day and levels rise immediately after meal intake. 
GLP-1 and GIP increase insulin biosynthesis and secretion from pancreatic beta cells in the presence 
of normal and elevated blood glucose levels. Furthermore GLP-1 also reduces glucagon secretion from 
pancreatic alpha cells, resulting in a reduction in hepatic glucose output. Linagliptin binds very 
effectively to DPP-4 in a reversible manner and thus leads to a sustained increase and a prolongation 
of active incretin levels. Linagliptin glucose-dependently increases insulin secretion and lowers 
glucagon secretion thus resulting in an overall improvement in the glucose homeostasis. Linagliptin 
binds selectively to DPP-4 and exhibits a > 10,000 fold selectivity versus DPP-8 or DPP-9 activity in
vitro.

Metformin
Mechanism of action
Metformin hydrochloride is a biguanide with antihyperglycaemic effects, lowering both basal and
postprandial plasma glucose. It does not stimulate insulin secretion and therefore does not produce 
hypoglycaemia. 

Metformin hydrochloride may act via 3 mechanisms: 

(1) reduction of hepatic glucose production by inhibiting gluconeogenesis and glycogenolysis,
(2) in muscle, by increasing insulin sensitivity, improving peripheral glucose uptake and utilisation,



13

(3) and delay of intestinal glucose absorption. 

Metformin hydrochloride stimulates intracellular glycogen synthesis by acting on glycogen synthase. 
Metformin hydrochloride increases the transport capacity of all types of membrane glucose 
transporters (GLUTs) known to date. 

In humans, independently of its action on glycaemia, metformin hydrochloride has favourable effects 
on lipid metabolism. This has been shown at therapeutic doses in controlled, medium-term or long-
term clinical studies: metformin hydrochloride reduces total cholesterol, LDL cholesterol and 
triglyceride levels.

Clinical efficacy and safety

Linagliptin as add-on to metformin therapy
The efficacy and safety of linagliptin in combination with metformin in patients with insufficient 
glycaemic control on metformin monotherapy was evaluated in a double-blind placebo-controlled 
study of 24 weeks duration. Linagliptin added to metformin provided significant improvements in 
HbA1c, (-0.64% change compared to placebo), from a mean baseline HbA1c of 8%. Linagliptin also 
showed significant improvements in fasting plasma glucose (FPG) by -21.1 mg/dl and 2-hour post-
prandial glucose (PPG) by -67.1 mg/dl compared to placebo, as well as a greater portion of patients 
achieving a target HbA1c of < 7.0% (28.3% on linagliptin versus 11.4% on placebo). The observed 
incidence of hypoglycaemia in patients treated with linagliptin was similar to placebo. Body weight 
did not differ significantly between the groups.

In a 24-week placebo-controlled factorial study of initial therapy, linagliptin 2.5 mg twice daily in 
combination with metformin (500 mg or 1,000 mg twice daily) provided significant improvements in 
glycaemic parameters compared with either monotherapy as summarised in Table 3 (mean baseline 
HbA1c 8.65%).

Mean reductions from baseline in HbA1c were generally greater for patients with higher baseline 
HbA1c values. Effects on plasma lipids were generally neutral. The decrease in body weight with the 
combination of linagliptin and metformin was similar to that observed for metformin alone or placebo; 
there was no change in weight from baseline for patients on linagliptin alone. The incidence of 



14

hypoglycaemia was similar across treatment groups (placebo 1.4%, linagliptin 5 mg 0%, metformin 
2.1%, and linagliptin 2.5 mg plus metformin twice daily 1.4%).

The efficacy and safety of linagliptin 2.5 mg twice daily versus 5 mg once daily in combination with 
metformin in patients with insufficient glycaemic control on metformin monotherapy was evaluated in 
a double-blind placebo-controlled study of 12 weeks duration. Linagliptin 5 mg once daily and 2.5 mg 
twice daily provided comparable (CI: -0.07; 0.19) significant HbA1c reductions of -0.80% (from 
baseline 7.98%), and -0.74% (from baseline 7.96%) compared to placebo. The observed incidence of 
hypoglycaemia in patients treated with linagliptin was similar to placebo. Body weight did not differ 
significantly between the groups.

Linagliptin as add-on to a combination of metformin and sulphonylurea therapy
A placebo-controlled study of 24 weeks in duration was conducted to evaluate the efficacy and safety 
of linagliptin 5 mg to placebo, in patients not sufficiently treated with a combination with metformin 
and a sulphonylurea. Linagliptin provided significant improvements in HbA1c (-0.62% change 
compared to placebo), from a mean baseline HbA1c of 8.14%. Linagliptin also showed significant 
improvements in patients achieving a target HbA1c of < 7.0% (31.2% on linagliptin versus 9.2% on 
placebo), and also for fasting plasma glucose (FPG) with -12.7 mg/dl reduction compared to placebo.
Body weight did not differ significantly between the groups.

Linagliptin as add on to a combination of metformin and empagliflozin therapy
In patients inadequately controlled with metformin and empagliflozin (10 mg (n=247) or 25 mg 
(n=217)), 24-weeks treatment with add-on therapy of linagliptin 5 mg provided adjusted mean HbA1c 
reductions from baseline by -0.53% (significant difference to add-on placebo -0.32% (95% CI -0.52, 
-0.13) and -0.58% (significant difference to add-on placebo -0.47% (95% CI -0.66; -0.28), 
respectively. A statistically significant greater proportion of patients with a baseline HbA1c ≥7.0% and 
treated with linagliptin 5 mg achieved a target HbA1c of <7% compared to placebo.

Linagliptin in combination with metformin and insulin
A 24-week placebo-controlled study was conducted to evaluate the efficacy and safety of linagliptin 
(5 mg once daily) added to insulin with or without metformin. 83% of patients were taking metformin 
in combination with insulin in this trial. Linagliptin in combination with metformin plus insulin 
provided significant improvements in HbA1c in this subgroup with -0.68% (CI: -0.78; -0,57) adjusted 
mean change from baseline (mean baseline HbA1c 8.28%) compared to placebo in combination with 
metformin plus insulin. There was no meaningful change from baseline in body weight in either 
group.

Linagliptin 24 month data, as add-on to metformin in comparison with glimepiride 
In a study comparing the efficacy and safety of the addition of linagliptin 5 mg or glimepiride (mean 
dose 3 mg) in patients with inadequate glycaemic control on metformin monotherapy, mean reductions 
in HbA1c were -0.16% with linagliptin (mean baseline HbA1c 7.69%) and -0.36% with glimepiride 
(mean baseline HbA1c 7.69%.) with a mean treatment difference of 0.20% (97.5% CI: 0.09, 0.299). 
The incidence of hypoglycaemia in the linagliptin group (7.5%) was significantly lower than that in 
the glimepiride group (36.1%). Patients treated with linagliptin exhibited a significant mean decrease 
from baseline in body weight compared to a significant weight gain in patients administered 
glimepiride (-1.39 versus +1.29 kg). 

Linagliptin as add-on therapy in elderly (age ≥ 70 years) with type 2 diabetes
The efficacy and safety of linagliptin in elderly (age ≥ 70 years) with type 2 diabetes was evaluated in 
a double-blind study of 24 weeks duration. Patients received metformin and/or sulphonylurea and/or
insulin as background therapy. Doses of background anti-diabetic therapy were kept stable during the 
first 12 weeks, after which adjustments were permitted. Linagliptin provided significant improvements 
in HbA1c (-0.64% change compared to placebo after 24 weeks), from a mean baseline HbA1c of 7.8%. 
Linagliptin also showed significant improvements in fasting plasma glucose (FPG) compared to 
placebo. Body weight did not differ significantly between the groups.



15

In a pooled analysis of elderly (age ≥ 70 years) patients with type 2 diabetes (n=183) who were taking 
both metformin and basal insulin as background therapy, linagliptin in combination with metformin 
plus insulin provided significant improvements in HbA1c parameters with -0.81% (CI: -1.01; -0.61) 
adjusted mean change from baseline (mean baseline HbA1c 8.13%) compared to placebo in 
combination with metformin plus insulin. 

Linagliptin cardiovascular and renal safety study (CARMELINA)
CARMELINA was a randomized study in 6979 patients with type 2 diabetes with increased CV risk 
evidenced by a history of established macrovascular or renal disease who were treated with linagliptin 
5 mg (3494) or placebo (3485) added to standard of care targeting regional standards for HbA1c, CV 
risk factors and renal disease. The study population included 1211 (17.4%) patients ≥ 75 years of age 
and 4348 (62.3%) patients with renal impairment. Approximately 19% of the population had eGFR 
≥45 to <60 mL/min/1.73 m2, 28% of the population had eGFR ≥30 to <45 mL/min/1.73 m2) and 15% 
had eGFR < 30 mL/min/1.73 m2. The mean HbA1c at baseline was 8.0%.

The study was designed to demonstrate non-inferiority for the primary cardiovascular endpoint which 
was a composite of the first occurrence of cardiovascular death or a non-fatal myocardial infarction 
(MI) or a non-fatal stroke (3P-MACE). The renal composite endpoint was defined as renal death or 
sustained end stage renal disease or sustained decrease of 40% or more in eGFR.

After a median follow up of 2.2 years, linagliptin, when added to standard of care, did not increase the 
risk of major adverse cardiovascular events or renal outcome events. There was no increased risk in 
hospitalization for heart failure which was an additional adjudicated endpoint observed compared to 
standard of care without linagliptin in patients with type 2 diabetes (table 4).

In analyses for albuminuria progression (change from normoalbuminuria to micro- or 
macroalbuminuria, or from microalbuminuria to macroalbuminuria) the estimated hazard ratio was 
0.86 (95% CI 0.78, 0.95) for linagliptin versus placebo. 

Linagliptin cardiovascular safety study (CAROLINA) 
CAROLINA was a randomized study in 6033 patients with early type 2 diabetes and increased CV 
risk or established complications who were treated with linagliptin 5 mg (3023) or glimepiride 1-4mg 
(3010) added to standard of care (including background therapy with metformin in 83% of patients) 
targeting regional standards for HbA1c and CV risk factors. The mean age for study population was 
64 years and included 2030 (34%) patients ≥ 70 years of age. The study population included 
2089 (35%) patients with cardiovascular disease and 1130 (19%) patients with renal impairment with 
an eGFR < 60ml/min/1.73m2 at baseline. The mean HbA1c at baseline was 7.15%.

The study was designed to demonstrate non-inferiority for the primary cardiovascular endpoint which 
was a composite of the first occurrence of cardiovascular death or a non-fatal myocardial infarction 
(MI) or a non-fatal stroke (3P-MACE). 

After a median follow up of 6.25 years, linagliptin, when added to standard of care, did not increase 
the risk of major adverse cardiovascular events (table 5) as compared to glimepiride. Results were 
consistent for patients treated with or without metformin.

For the entire treatment period (median time on treatment 5.9 years) the rate of patients with moderate 
or severe hypoglycaemia was 6.5% on linagliptin versus 30.9% on glimepiride, severe hypoglycaemia 
occurred in 0.3% of patients on linagliptin versus 2.2% on glimepiride.

Metformin 
The prospective randomised (UKPDS) study has established the long-term benefit of intensive blood 
glucose control in type 2 diabetes. Analysis of the results for overweight patients treated with 
metformin after failure of diet alone showed:

• a significant reduction of the absolute risk of any diabetes-related complication in the metformin 
group (29.8 events/1,000 patient-years) versus diet alone (43.3 events/1,000 patient-years), 
p=0.0023, and versus the combined sulphonylurea and insulin monotherapy groups 
(40.1 events/1,000 patient-years), p=0.0034,

• a significant reduction of the absolute risk of any diabetes-related mortality: metformin 
7.5 events/1,000 patient-years, diet alone 12.7 events/1,000 patient-years, p=0.017,



17

• a significant reduction of the absolute risk of overall mortality: metformin 
13.5 events/1,000 patient-years versus diet alone 20.6 events/1,000 patient-years, (p=0.011), and 
versus the combined sulphonylurea and insulin monotherapy groups 18.9 events/1,000 patient-
years (p=0.021),

• a significant reduction in the absolute risk of myocardial infarction: metformin 
11 events/1,000 patient-years, diet alone 18 events/1,000 patient-years, (p=0.01).

Paediatric population
The European Medicines Agency has waived the obligation to submit the results of the studies with 
Jentadueto in all subsets of the paediatric population in type 2 diabetes (see section 4.2 for information 
on paediatric use).

5.2 Pharmacokinetic properties

Bioequivalence studies in healthy subjects demonstrated that the Jentadueto (linagliptin/metformin
hydrochloride) combination tablets are bioequivalent to co-administration of linagliptin and metformin 
hydrochloride as individual tablets.

Administration of Jentadueto 2.5/1,000 mg with food resulted in no change in overall exposure of 
linagliptin. With metformin there was no change in AUC, however mean peak serum concentration of 
metformin was decreased by 18% when administered with food. A delayed time to peak serum 
concentrations by 2 hours was observed for metformin under fed conditions. These changes are not 
likely to be clinically meaningful.

The following statements reflect the pharmacokinetic properties of the individual active substances of 
Jentadueto.

Linagliptin
The pharmacokinetics of linagliptin has been extensively characterised in healthy subjects and patients 
with type 2 diabetes. After oral administration of a 5 mg dose to healthy volunteers or patients, 
linagliptin was rapidly absorbed, with peak plasma concentrations (median Tmax) occurring 1.5 hours 
post-dose.

Plasma concentrations of linagliptin decline in a triphasic manner with a long terminal half-life 
(terminal half-life for linagliptin more than 100 hours), that is mostly related to the saturable, tight 
binding of linagliptin to DPP-4 and does not contribute to the accumulation of the active substance. 
The effective half-life for accumulation of linagliptin, as determined from oral administration of 
multiple doses of 5 mg linagliptin, is approximately 12 hours. After once daily dosing of 5 mg 
linagliptin, steady-state plasma concentrations are reached by the third dose. Plasma AUC of 
linagliptin increased approximately 33% following 5 mg doses at steady-state compared to the first 
dose. The intra-subject and inter-subject coefficients of variation for linagliptin AUC were small 
(12.6% and 28.5%, respectively). Due to the concentration dependent binding of linagliptin to DPP-
IV, the pharmacokinetics of linagliptin based on total exposure is not linear; indeed total plasma AUC 
of linagliptin increased in a less than dose-proportional manner, while unbound AUC increases in a 
roughly dose-proportional manner. The pharmacokinetics of linagliptin was generally similar in 
healthy subjects and in patients with type 2 diabetes.

Absorption
The absolute bioavailability of linagliptin is approximately 30%. Co-administration of a high-fat meal 
with linagliptin prolonged the time to reach Cmax by 2 hours and lowered Cmax by 15%, but no 
influence on AUC 0-72h was observed. No clinically relevant effect of Cmax and Tmax changes is 
expected; therefore linagliptin may be administered with or without food. 



18

Distribution
As a result of tissue binding, the mean apparent volume of distribution at steady-state following a 
single 5 mg intravenous dose of linagliptin to healthy subjects is approximately 1110 litres, indicating 
that linagliptin extensively distributes to the tissues. Plasma protein binding of linagliptin is 
concentration-dependent, decreasing from about 99% at 1 nmol/l to 75-89% at ≥ 30 nmol/l, reflecting 
saturation of binding to DPP-4 with increasing concentration of linagliptin At high concentrations, 
where DPP-4 is fully saturated, 70-80% of linagliptin was bound to other plasma proteins than DPP-4, 
hence 20-30% were unbound in plasma.

Biotransformation
Following a [14C] linagliptin oral 10 mg dose, approximately 5% of the radioactivity was excreted in 
urine. Metabolism plays a subordinate role in the elimination of linagliptin. One main metabolite with 
a relative exposure of 13.3% of linagliptin at steady-state was detected which was found to be 
pharmacologically inactive, and thus does not contribute to the plasma DPP-4 inhibitory activity of 
linagliptin.

Elimination
Following administration of an oral [14C] linagliptin dose to healthy subjects, approximately 85% of 
the administered radioactivity was eliminated in faeces (80%) or urine (5%) within 4 days of dosing. 
Renal clearance at steady-state was approximately 70 ml/min.

Renal impairment
Under steady-state conditions, linagliptin exposure in patients with mild renal impairment was 
comparable to healthy subjects. In moderate renal impairment, a moderate increase in exposure of 
about 1.7 fold was observed compared with control. Exposure in T2DM patients with severe RI was 
increased by about 1.4 fold compared to T2DM patients with normal renal function. Steady-state 
predictions for AUC of linagliptin in patients with ESRD indicated comparable exposure to that of 
patients with moderate or severe renal impairment. In addition, linagliptin is not expected to be 
eliminated to a therapeutically significant degree by hemodialysis or peritoneal dialysis. No dose 
adjustment of linagliptin is recommended in patients with renal impairment; therefore, linagliptin may 
be continued as a single entity tablet at the same total daily dose of 5 mg if Jentadueto is discontinued 
due to evidence of renal impairment.

Hepatic impairment
In patients with mild moderate and severe hepatic impairment (according to the Child-Pugh 
classification), mean AUC and Cmax of linagliptin were similar to healthy matched controls following 
administration of multiple 5 mg doses of linagliptin. 

Body Mass Index (BMI)
Body mass index had no clinically relevant effect on the pharmacokinetics of linagliptin based on a 
population pharmacokinetic analysis of Phase I and Phase II data. The clinical trials before marketing 
authorization have been performed up to a BMI equal to 40 kg/m2.

Gender
Gender had no clinically relevant effect on the pharmacokinetics of linagliptin based on a population 
pharmacokinetic analysis of Phase I and Phase II data. 

Elderly
Age did not have a clinically relevant impact on the pharmacokinetics of linagliptin based on a 
population pharmacokinetic analysis of Phase I and Phase II data. Older subjects (65 to 80 years, 
oldest patient was 78 years) had comparable plasma concentrations of linagliptin compared to younger 
subjects. Linagliptin trough concentrations were also measured in elderly (age ≥ 70 years) with type 2 
diabetes in a phase III study of 24 weeks duration. Linagliptin concentrations in this study were within 
the range of values previously observed in younger type 2 diabetes patients.



19

Paediatric population
A paediatric Phase 2 study examined the pharmacokinetics and pharmacodynamics of 1 mg and 5 mg 
linagliptin in children and adolescents ≥10 to <18 years of age with type 2 diabetes mellitus. The 
observed pharmacokinetic and pharmacodynamic responses were consistent with those found in adult 
subjects. Linagliptin 5 mg showed superiority over 1 mg with regard to trough DPP-4 inhibition (72% 
vs 32%, p=0.0050) and a numerically larger reduction with regard to adjusted mean change from 
baseline in HbA1c (-0.63% vs -0.48%, n.s.). Due to the limited nature of the data set the results should 
be interpreted cautiously.

Race
Race had no obvious effect on the plasma concentrations of linagliptin based on a composite analysis 
of available pharmacokinetic data, including patients of Caucasian, Hispanic, African, and Asian 
origin. In addition the pharmacokinetic characteristics of linagliptin were found to be similar in 
dedicated phase I studies in Japanese, Chinese and Caucasian healthy subjects and African American 
type 2 diabetes patients. 

Metformin
Absorption
After an oral dose of metformin, Tmax is reached in 2.5 hours. Absolute bioavailability of a 500 mg or 
850 mg metformin hydrochloride tablet is approximately 50-60% in healthy subjects. After an oral 
dose, the non-absorbed fraction recovered in faeces was 20-30%.

After oral administration, metformin hydrochloride absorption is saturable and incomplete. It is 
assumed that the pharmacokinetics of metformin hydrochloride absorption are non-linear.

At the recommended metformin hydrochloride doses and dosing schedules, steady-state plasma 
concentrations are reached within 24 to 48 hours and are generally less than 1 microgram/ml. In 
controlled clinical trials, maximum metformin hydrochloride plasma levels (Cmax) did not exceed 
5 microgram/ml, even at maximum doses.

Food decreases the extent and slightly delays the absorption of metformin hydrochloride. Following 
administration of a dose of 850 mg, a 40% lower plasma peak concentration, a 25% decrease in AUC 
(area under the curve) and a 35 minute prolongation of the time to peak plasma concentration were 
observed. The clinical relevance of these decreases is unknown. 

Distribution
Plasma protein binding is negligible. Metformin hydrochloride partitions into erythrocytes. The blood 
peak is lower than the plasma peak and appears at approximately the same time. The red blood cells 
most likely represent a secondary compartment of distribution. The mean volume of distribution (Vd) 
ranged between 63-276 l. 

Biotransformation
Metformin hydrochloride is excreted unchanged in the urine. No metabolites have been identified in 
humans. 

Elimination
Renal clearance of metformin hydrochloride is > 400 ml/min, indicating that metformin hydrochloride 
is eliminated by glomerular filtration and tubular secretion. Following an oral dose, the apparent 
terminal elimination half-life is approximately 6.5 hours. 
When renal function is impaired, renal clearance is decreased in proportion to that of creatinine and 
thus the elimination half-life is prolonged, leading to increased levels of metformin hydrochloride in 
plasma.

Paediatric population
Single dose study: after single doses of metformin hydrochloride 500 mg, paediatric patients have 
shown a similar pharmacokinetic profile to that observed in healthy adults. 



20

Multiple-dose study: data are restricted to one study. After repeated doses of 500 mg twice daily for 7 
days in paediatric patients the peak plasma concentration (Cmax) and systemic exposure (AUC0-t) were 
reduced by approximately 33% and 40%, respectively compared to diabetic adults who received 
repeated doses of 500 mg twice daily for 14 days. As the dose is individually titrated based on 
glycaemic control, this is of limited clinical relevance.

5.3 Preclinical safety data

Linagliptin plus metformin
General toxicity studies in rats for up to 13 weeks were performed with the co-administration of 
linagliptin and metformin. The only observed interaction between linagliptin and metformin was a 
reduction of body weight gain. No other additive toxicity caused by the combination of linagliptin and 
metformin was observed at AUC exposure levels up to 2 and 23 times human exposure, respectively.

An embryofetal development study in pregnant rats did not indicate a teratogenic effect attributed to 
the co-administration of linagliptin and metformin at AUC exposure levels up to 4 and 30 times 
human exposure, respectively.

Linagliptin
Liver, kidneys and gastrointestinal tract are the principal target organs of toxicity in mice and rats at 
repeat doses of linagliptin of more than 300 times the human exposure.
In rats, effects on reproductive organs, thyroid and the lymphoid organs were seen at more than 
1500 times human exposure. Strong pseudo-allergic reactions were observed in dogs at medium doses, 
secondarily causing cardiovascular changes, which were considered dog-specific. Liver, kidneys, 
stomach, reproductive organs, thymus, spleen, and lymph nodes were target organs of toxicity in 
Cynomolgus monkeys at more than 450 times human exposure. At more than 100 times human 
exposure, irritation of the stomach was the major finding in these monkeys.

Linagliptin and its main metabolite did not show a genotoxic potential.
Oral 2 year carcinogenicity studies in rats and mice revealed no evidence of carcinogenicity in rats or 
male mice. A significantly higher incidence of malignant lymphomas only in female mice at the 
highest dose (> 200 times human exposure) is not considered relevant for humans (explanation: non-
treatment related but due to highly variable background incidence). Based on these studies there is no 
concern for carcinogenicity in humans.

The NOAEL for fertility, early embryonic development and teratogenicity in rats was set at 
> 900 times the human exposure. The NOAEL for maternal-, embryo-fetal-, and offspring toxicity in 
rats was 49 times human exposure. No teratogenic effects were observed in rabbits at > 1,000 times 
human exposure. A NOAEL of 78 times human exposure was derived for embryo-fetal toxicity in 
rabbits, and for maternal toxicity the NOAEL was 2.1 times human exposure. Therefore, it is 
considered unlikely that linagliptin affects reproduction at therapeutic exposures in humans.

Metformin
Non-clinical data reveal no special hazard for humans based on conventional studies of safety 
pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential, toxicity to reproduction 
and development.

6. Contents of the pack and other information

1. What Jentadueto is and what it is used for

The name of your tablet is Jentadueto. It contains two different active substances linagliptin and 
metformin.
- Linagliptin belongs to a class of medicines called DPP-4 inhibitors (dipeptidyl peptidase-4 

inhibitors).
- Metformin belongs to a class of medicines called biguanides.

How Jentadueto works
The two active substances work together to control blood sugar levels in adult patients with a form of 
diabetes called ‘type 2 diabetes mellitus’. Along with diet and exercise, this medicine helps to improve 
the levels and effects of insulin after a meal and lowers the amount of sugar made by your body.

This medicine can be used alone or with certain other medicines for diabetes like sulphonylureas, 
empagliflozin, or insulin.

What is type 2 diabetes?

Type 2 diabetes is a condition in which your body does not make enough insulin, and the insulin that 
your body produces does not work as well as it should. Your body can also make too much sugar. 
When this happens, sugar (glucose) builds up in the blood. This can lead to serious medical problems 
like heart disease, kidney disease, blindness, and amputation.

2. What you need to know before you take Jentadueto

Do not take Jentadueto
- if you are allergic to linagliptin or metformin or any of the other ingredients of this medicine

(listed in section 6).
- if you have severely reduced kidney function.



50

if you have uncontrolled diabetes, with, for example, severe hyperglycaemia (high blood 
glucose), nausea, vomiting, diarrhoea, rapid weight loss, lactic acidosis (see “Risk of lactic 
acidosis” below) or ketoacidosis. Ketoacidosis is a condition in which substances called ‘ketone 
bodies’ accumulate in the blood and which can lead to diabetic pre-coma. Symptoms include 
stomach pain, fast and deep breathing, sleepiness or your breath developing an unusual fruity 
smell.

- if you ever had a diabetic pre-coma.
- if you have a severe infection such as an infection affecting your lung or bronchial system or 

your kidney. Severe infections may lead to kidney problems, which can put you at risk for lactic 
acidosis (see 'Warnings and precautions').

- if you have lost a lot of water from your body (dehydration), e.g. due to long-lasting or severe 
diarrhoea, or if you have vomited several times in a row. Dehydration may lead to kidney 
problems, which can put you at risk for lactic acidosis (see 'Warnings and precautions').

- if you are treated for acute heart failure or have recently had a heart attack, have severe 
problems with your circulation (such as shock) or have breathing difficulties. This may lead to a 
lack in oxygen supply to tissue which can put you at risk for lactic acidosis (see 'Warnings and 
precautions').

- if you have liver problems.
- if you drink alcohol to excess, either every day or only from time to time (see section 

'Jentadueto with alcohol').

Do not take Jentadueto if any of the above applies to you. If you are not sure, talk to your doctor or
pharmacist before taking this medicine.

Warnings and precautions
Talk to your doctor, pharmacist or nurse before taking Jentadueto
- if you have type 1 diabetes (your body does not produce any insulin). Jentadueto should not be 

used to treat this condition.
- if you are taking insulin or an anti-diabetic medicine known as ‘sulphonylurea’, your doctor may 

want to reduce your dose of insulin or sulphonylurea when you take either of them together with 
Jentadueto in order to avoid low blood sugar (hypoglycaemia).

- if you have or have had a disease of the pancreas.

If you have symptoms of acute pancreatitis, like persistent, severe abdominal pain, you should consult
your doctor.

If you encounter blistering of the skin it may be a sign for a condition called bullous pemphigoid. 
Your doctor may ask you to stop Jentadueto.

If you are not sure if any of the above applies to you, talk to your doctor, pharmacist or nurse before 
taking Jentadueto.

Diabetic skin problems are a common complication of diabetes. You are advised to follow the 
recommendations for skin and foot care that you are given by your doctor or nurse.

Risk of lactic acidosis.
Due to the metformin component, Jentadueto may cause a very rare, but very serious complication 
called lactic acidosis, particularly if your kidneys are not working properly. The risk of developing 
lactic acidosis is also increased with uncontrolled diabetes, serious infections, prolonged fasting or 
alcohol intake, dehydration(see further information below), liver problems and any medical conditions 
in which a part of the body has a reduced supply of oxygen (such as acute severe heart disease).
If any of the above apply to you, talk to your doctor for further instructions.

Stop taking Jentadueto for a short time if you have a condition that may be associated with 
dehydration (significant loss of body fluids) such as severe vomiting, diarrhoea, fever, exposure to 
heat or if you drink less fluid than normal. Talk to your doctor for further instruction.



51

Stop taking Jentadueto and contact a doctor or the nearest hospital immediately if you 
experience some of the symptoms of lactic acidosis, as this condition may lead to coma.
Symptoms of lactic acidosis include:
- vomiting
- stomach ache (abdominal pain)
- muscle cramps
- a general feeling of not being well with severe tiredness
- difficulty in breathing
- reduced body temperature and heartbeat

Lactic acidosis is a medical emergency and must be treated in a hospital.

If you need to have major surgery you must stop taking Jentadueto during and for some time after the 
procedure. Your doctor will decide when you must stop and when to restart your treatment with 
Jentadueto.

During treatment with Jentadueto, your doctor will check your kidney function at least once a year or
more frequently if you are elderly and/or if you have worsening kidney function.

Children and adolescents
This medicine is not recommended for use in children and adolescents under 18 years.

Other medicines and Jentadueto
If you need to have an injection of a contrast medium that contains iodine into your bloodstream, for 
example in the context of an X-ray or scan, you must stop taking Jentadueto before or at the time of 
the injection. Your doctor will decide when you must stop and when to restart your treatment with 
Jentadueto.

Tell your doctor if you are taking, have recently taken or might take any other medicines. You may 
need more frequent blood glucose and kidney function tests, or your doctor may need to adjust the 
dosage of Jentadueto. It is especially important to mention the following:
- medicines which increase urine production (diuretics)
- medicines used to treat pain and inflammation (NSAID and COX-2-inhibitors, such as ibuprofen 

and celecoxib)
- certain medicines for the treatment of high blood pressure (ACE inhibitors and angiotensin II 

receptor antagonists)
- medicines that may change the amount of metformin in your blood, especially if you have reduced 

kidney function (such as verapamil, rifampicin, cimetidine, dolutegravir, ranolazine, 
trimethoprime, vandetanib, isavuconazole, crizotinib, olaparib).

- carbamazepine, phenobarbital or phenytoin. These may be used to control fits (seizures) or chronic 
pain.

- rifampicin. This is an antibiotic used to treat infections such as tuberculosis.
- medicines used to treat diseases that involve inflammation, like asthma and arthritis

(corticosteroids).
- bronchodilators (β-sympathomimetics) for the treatment of bronchial asthma.
- alcohol-containing medicines.

Jentadueto with alcohol
Avoid excessive alcohol intake while taking Jentadueto since this may increase the risk of lactic 
acidosis (see section ‘Warnings and precautions’).

Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask 
your doctor or pharmacist for advice before taking this medicine.

You should not use Jentadueto if you are pregnant. It is unknown if this medicine is harmful to the 
unborn child.



52

Metformin passes into human milk in small amounts. It is not known whether linagliptin passes into
human milk. Talk to your doctor if you want to breast-feed while taking this medicine.

Driving and using machines
Jentadueto has no or negligible influence on the ability to drive and use machines.

However, taking Jentadueto in combination with medicines called sulphonylureas or with insulin can 
cause too low blood sugar level (hypoglycaemia), which may affect your ability to drive and use 
machines or work without safe foothold.

3. How to take Jentadueto

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor 
or pharmacist if you are not sure.

How much to take
The amount of Jentadueto that you will take varies depending on your condition and the doses you 
currently take of metformin and/or individual tablets of linagliptin and metformin. Your doctor will 
tell you exactly the dose of this medicine to take.

How to take this medicine
- one tablet twice daily by mouth in the dose prescribed by your doctor.
- with meals to lower your chance of an upset stomach.

You should not exceed the maximum recommended daily dose of 5 mg linagliptin and 2,000 mg 
metformin hydrochloride.

Continue to take Jentadueto as long as your doctor prescribes it so you can continue to help control 
your blood sugar. Your doctor may prescribe this medicine together with another oral anti-diabetic 
medicine or insulin. Remember to take all medicines as directed by your doctor to achieve the best 
results for your health.

You should continue your diet during treatment with Jentadueto and take care that your carbohydrate
intake is equally distributed over the day. If you are overweight, continue your energy-restricted diet 
as instructed. This medicine alone is unlikely to cause abnormally low blood sugar (hypoglycaemia). 
When Jentadueto is used with a sulphonylurea medicine or with insulin, low blood sugar can occur 
and your doctor may reduce the dose of your sulphonylurea or insulin.

If you take more Jentadueto than you should
If you take more Jentadueto tablets than you should have, you may experience lactic acidosis. 
Symptoms of lactic acidosis are non-specific such as feeling or being very sick, vomiting, stomach 
ache with muscle cramps, a general feeling of not being well with severe tiredness, and difficulty in 
breathing. Further symptoms are reduced body temperature and heartbeat. If this happens to you, you 
may need immediate hospital treatment, as lactic acidosis can lead to coma. Stop taking this 
medicine immediately and contact a doctor or the nearest hospital straight away (see section 2). 
Take the medicine pack with you.

If you forget to take Jentadueto
If you forget to take a dose, take it as soon as you remember it. However, if it is nearly time for the 
next dose, skip the missed dose. Do not take a double dose to make up for a forgotten dose. Never take 
two doses at the same time (morning or evening).

If you stop taking Jentadueto
Keep taking Jentadueto until your doctor tells you to stop. This is to help keep your blood sugar under 
control. 



53

If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Some symptoms need immediate medical attention
You should stop taking Jentadueto and see your doctor straight away if you experience the following 
symptoms of low blood sugar (hypoglycaemia): trembling, sweating, anxiety, blurred vision, tingling 
lips, paleness, mood change, or confusion. Hypoglycaemia (frequency very common (may affect more 
than 1 in 10 people)) is an identified side effect for the combination of Jentadueto plus sulphonylurea
and for the combination Jentadueto plus insulin.

Jentadueto may cause a very rare (may affect up to 1 user in 10,000), but very serious side effect 
called lactic acidosis (see section ‘Warnings and precautions’). If this happens you must stop taking 
Jentadueto and contact a doctor or the nearest hospital immediately, as lactic acidosis may lead to 
coma.

Some patients have experienced inflammation of the pancreas (pancreatitis; frequency rare, may affect 
up to 1 in 1000 people). 
STOP taking Jentadueto and contact a doctor immediately if you notice any of the following serious 
side effects:
- Severe and persistent pain in the abdomen (stomach area) which might reach through to your 

back, as well as nausea and vomiting, as it could be a sign of an inflamed pancreas 
(pancreatitis).

Other side effects of Jentadueto include:
Some patients have experienced allergic reactions (frequency rare), which may be serious, including 
wheezing and shortness of breath (bronchial hyperreactivity; frequency uncommon (may affect up to 1 
in 100 people)). Some patients experienced rash (frequency uncommon), hives (urticaria; frequency 
rare), and swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or 
swallowing (angioedema; frequency rare). If you experience any of the signs of illness mentioned 
above, stop taking Jentadueto and call your doctor right away. Your doctor may prescribe a medicine 
to treat your allergic reaction and a different medicine for your diabetes.

Some patients have had the following side effects while taking Jentadueto:
- Common (may affect up to 1 in 10 people): diarrhoea, blood enzyme increase (lipase increase),
