Read the Medication Guide that comes with LEVAQUIN before you start taking it and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking to your healthcare provider about your medical condition or your treatment.

## What is the most important information I should know about LEVAQUIN?
LEVAQUIN belongs to a class of antibiotics called fluoroquinolones. LEVAQUIN 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 LEVAQUIN.
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 LEVAQUIN. 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 withrheumatoid arthritis (RA).
Call your healthcare provider right away at the first sign of tendon pain, swelling or inflammation. Stop taking LEVAQUIN 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 LEVAQUIN. 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 LEVAQUIN. 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 LEVAQUIN?" for more information about side effects

## What is LEVAQUIN?
LEVAQUIN is a fluoroquinolone antibiotic medicine used in adults, 18 years or older, to treat certain infections caused by certain germs called bacteria.
Children have a higher chance of getting bone, joint, or tendon (musculoskeletal) problems such as pain or swelling while taking LEVAQUIN.
In children 6 months and older who have breathed the anthrax bacteria germ:
LEVAQUIN is used to prevent anthrax disease (inhalation anthrax).
It is not known if it is safe to use LEVAQUIN in children for more than 14 days.
It is not known if LEVAQUIN is safe and works in children under the age of 6 months.
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 LEVAQUIN, do not kill viruses.
Call your healthcare provider if you think your condition is not getting better while you are taking LEVAQUIN.

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

## What should I tell my healthcare provider before taking LEVAQUIN?
See "What is the most important information I should know about LEVAQUIN?"
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)
have a history of seizures
have bone and joint problems
have kidney problems. You may need a lower dose of LEVAQUIN if your kidneys do not work well.
have liver problems
have rheumatoid arthritis (RA) or other history of joint problems
are pregnant or planning to become pregnant. It is not known if LEVAQUIN will harm your unborn child.
are breast-feeding or planning to breast-feed. LEVAQUIN is thought to pass into breast milk. You and your healthcare provider should decide whether you will take LEVAQUIN or breast-feed.
Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, herbal and dietary supplements. LEVAQUIN 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 LEVAQUINor other fluoroquinolones may increase your risk of central nervous system effects and seizures. See "What are the possible side effects of LEVAQUIN?"
an oral anti-diabetes medicine or insulin
a blood thinner (warfarin, Coumadin, Jantoven)
a medicine to control your heart rate or rhythm (antiarrhythmics). See "What are the possible side effects of LEVAQUIN".
an anti-psychotic medicine
a tricyclic antidepressant
a water pill (diuretic)
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 LEVAQUIN?".
theophylline (Theo-24, Elixophyllin, Theochron, Uniphyl, Theolair)
Certain medicines may keep LEVAQUIN from working correctly. Take LEVAQUIN Tablets or Oral Solution either 2 hours before or 2 hours after taking these products:
an antacid, multivitamin, or other product that has magnesium, aluminum, iron, or zinc.
sucralfate (Carafate)
didanosine (Videx,Videx EC)

LEVAQUIN for Injection is given to you by intravenous (I.V.) infusion into your vein, slowly, over 60 or 90 minutes, as prescribed by your healthcare provider. See "What are the

## possible side effects of LEVAQUIN?"
Do not skip any doses, or stop taking LEVAQUIN 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 LEVAQUIN?"),
you have a serious allergic reaction (see "What are the possible side effects of LEVAQUIN?"), or

This will help make sure that all of the bacteria are killed and lower the chance that the bacteria will become resistant to LEVAQUIN. If this happens, LEVAQUIN and other antibiotic medicines may not work in the future.
If you take too much, call your healthcare provider or get medical help immediately.
If you have been prescribed LEVAQUIN after being exposed to anthrax:
LEVAQUIN has been approved to lessen the chance of getting anthrax disease or worsening of the disease after you are exposed to the anthrax bacteria germ.
Take LEVAQUIN exactly as prescribed by your healthcare provider. Do not stop taking LEVAQUIN without talking with your healthcare provider. If you stop taking LEVAQUIN too soon, it may not keep you from getting the anthrax disease.
Side effects may happen while you are taking LEVAQUIN. When taking LEVAQUIN to prevent anthrax infection, you and your healthcare provider should talk about whether the risks of stopping your medicine too soon are more important than the risks of side effects with LEVAQUIN. It is not known if it is safe to use LEVAQUIN for more than 28 days in adults and for more than 14 days in children 6 months of age and older.
If you are pregnant, or plan to become pregnant while taking LEVAQUIN, you and your healthcare provider should decide whether the benefits of taking LEVAQUIN for anthrax are more important than the risks.
