Gemifloxacin(patient information)

# What is the most important information I should know about FACTIVE?
FACTIVE belongs to a class of antibiotics called fluoroquinolones. FACTIVE can cause side effects that may be serious or even cause death. If you get any of the following serious side effects, get medical help right away. Talk with your healthcare provider about whether you should continue to take FACTIVE.
Tendon rupture or swelling of the tendon (tendinitis)
Tendons are tough cords of tissue that connect muscles to bones.
Pain, swelling, tears, and inflammation of tendons including the back of the ankle (Achilles), shoulder, hand, or other tendon sites can happen in people of all ages who take fluoroquinolone antibiotics, including FACTIVE. The risk of getting tendon problems is higher if you:
are over 60 years of age
are taking steroids (corticosteroids)
have had a kidney, heart or lung transplant.
Swelling of the tendon (tendinitis) and tendon rupture (breakage) have also happened in patients who take fluoroquinolones who do not have the above risk factors.
Other reasons for tendon ruptures can include:
physical activity or exercise
kidney failure
tendon problems in the past, such as in people with rheumatoid arthritis (RA).
Call your healthcare provider right away at the first sign of tendon pain, swelling or inflammation. Stop taking FACTIVE until tendinitis or tendon rupture has been ruled out by your healthcare provider. Avoid exercise and using the affected area. The most common area of pain and swelling is the Achilles tendon at the back of your ankle. This can also happen with other tendons. Talk to your healthcare provider about the risk of tendon rupture with continued use of FACTIVE. You may need a different antibiotic that is not a fluoroquinolone to treat your infection.
Tendon rupture can happen while you are taking or after you have finished taking FACTIVE. Tendon ruptures have happened up to several months after patients have finished taking their fluoroquinolone.
Get medical help right away if you get any of the following signs or symptoms of a tendon rupture:
hear or feel a snap or pop in a tendon area
bruising right after an injury in a tendon area
unable to move the affected area or bear weight
See the section What are the possible side effects of FACTIVE? for more information about side effects.

# What is FACTIVE?
FACTIVE is a fluoroquinolone antibiotic medicine used to treat certain types of infections caused by certain germs called bacteria. It is not known if FACTIVE is safe and works in children under 18 years of age. Children have a higher chance of getting bone, joint, or tendon (musculoskeletal) problems such as pain or swelling while taking FACTIVE.
Sometimes infections are caused by viruses rather than by bacteria. Examples include viral infections in the sinuses and lungs, such as the common cold or flu. Antibiotics including FACTIVE do not kill viruses.
Call your healthcare provider if you think your condition is not getting better while you are taking FACTIVE.

# Who should not take FACTIVE?
Do not take FACTIVE if you have ever had a severe allergic reaction to an antibiotic known as a fluoroquinolone, or are allergic to any of the ingredients in FACTIVE. Ask your healthcare provider if you are not sure. See the list of ingredients in FACTIVE at the end of this Medication Guide.

# What should I tell my healthcare provider before taking FACTIVE?
See What is the most important information I should know about FACTIVE?
Tell your healthcare provider about all your medical conditions, including if you:
have tendon problems
have central nervous system problems (such as epilepsy)
have nerve problems
have or anyone in your family has an irregular heartbeat, especially a condition called QT prolongation
have low blood potassium (hypokalemia) or magnesium (hypomagnesemia)
have a slow heartbeat (bradycardia)
have a history of seizures
have kidney problems. You may need a lower dose of FACTIVE if your kidneys do not work well.
have rheumatoid arthritis (RA) or other history of joint problems
are pregnant or planning to become pregnant. It is not known if FACTIVE will harm your unborn child.
are breast-feeding or planning to breast-feed. It is not known if FACTIVE passes into breast milk. You and your healthcare provider should decide whether you will take FACTIVE or breast-feed.
Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal and dietary supplements. FACTIVE and other medicines can affect each other causing side effects. Especially tell your healthcare provider if you take:
an NSAID (Non-Steroidal Anti-Inflammatory Drug). Many common medicines for pain relief are NSAIDs. Taking an NSAID while you take FACTIVE or other fluoroquinolones may increase your risk of central nervous system effects and seizures. See What are the possible side effects of FACTIVE?
a blood thinner (warfarin, Coumadin, Jantoven)
a medicine to control your heart rate or rhythm (antiarrhythmics). See What are the possible side effects of FACTIVE?
erythromycin
an anti-psychotic medicine
a tricyclic antidepressant
a water pill (diuretic)
probenecid (Probalan, Col-Probenecid)
a steroid medicine. Corticosteroids taken by mouth or by injection may increase the chance of tendon injury. See What is the most important information I should know about FACTIVE?
Certain medicines may keep FACTIVE from working correctly. Take FACTIVE either 2 hours before or 3 hours after taking these products:
an antacid, multivitamin, or other product that contains magnesium, aluminum, iron, or zinc.
sucralfate (Carafate).
didanosine (Videx, Videx EC).
Ask your healthcare provider if you are not sure if any of your medicines are listed above.
Know the medicines you take. Keep a list of your medicines and show it to your healthcare provider and pharmacist when you get a new medicine.
How should I take FACTIVE?
Take FACTIVE exactly as prescribed by your healthcare provider.
Take FACTIVE at about the same time each day.
FACTIVE can be taken with or without food.
Swallow FACTIVE whole, and drink plenty of fluids with it. Do not chew FACTIVE. Tell your healthcare provider if you are not able to swallow FACTIVE whole. You will need to take a different antibiotic medicine.
Do not skip any doses, or stop taking FACTIVE even if you begin to feel better, until you finish your prescribed treatment, unless:
you have tendon effects (see What is the most important information I should know about FACTIVE?),
you have a serious allergic reaction (see What are the possible side effects of FACTIVE?), or
your healthcare provider tells you to stop.
This will help make sure that all of the bacteria are killed and lower the chance that the bacteria will become resistant to FACTIVE. If this happens, FACTIVE and other antibiotic medicines may not work in the future.
If you miss a dose of FACTIVE, take it as soon as you remember. Do not take more than 1 dose of FACTIVE in one day.
If you take too much, call your healthcare provider or get medical help immediately.

who are elderly
with a family history of prolonged QT interval
with low blood potassium (hypokalemia)
who take certain medicines to control heart rhythm (antiarrhythmics).
Intestine infection (Pseudomembranous colitis). Pseudomembranous colitis can happen with most antibiotics, including FACTIVE.
