Read the Medication Guide that comes with AVELOX® 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 AVELOX?
AVELOX belongs to a class of antibiotics called fluoroquinolones. AVELOX 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 AVELOX.
1. Tendon rupture or swelling of the tendon (tendinitis).
- Tendon problems can happen in people of all ages who
take AVELOX. Tendons are tough cords of tissue that connect muscles to
bones. Symptoms of tendon problems may include:
- Pain, swelling, tears and inflammation of tendons including the back of the ankle (Achilles), shoulder, hand, or other tendon sites.
- The risk of getting tendon problems while you take
AVELOX is higher if you:
- Are over 60 years of age
- Are taking steroids (corticosteroids)
- Have had a kidney, heart or lung transplant
Tendon problems can happen in people who do not have the above risk factors when they take AVELOX.
- Other reasons that can increase your risk of tendon
problems 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 AVELOX 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 in 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 AVELOX. 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 AVELOX. 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.
2. Worsening of myasthenia gravis (a disease which causes muscle weakness).
Fluoroquinolones like AVELOX may cause worsening of myasthenia gravis symptoms, including muscle weakness and breathing problems. Call your healthcare provider right away if you have any worsening muscle weakness or breathing problems.
See the section “What are the possible side effects of AVELOX?” for more information about side effects.
What is AVELOX?
AVELOX is a fluoroquinolone antibiotic medicine used to treat certain types of infections caused by certain germs called bacteria in adults 18 years or older. It is not known if AVELOX is safe and works in people under 18 years of age. Children have a higher chance of getting bone, joint, and tendon (musculoskeletal) problems while taking fluoroquinolone antibiotic medicines.
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 AVELOX, do not kill viruses. Call your healthcare provider if you think your condition is not getting better while you are taking AVELOX.
Who should not take AVELOX?
Do not take AVELOX 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 AVELOX. Ask your healthcare provider if you are not sure. See the list of ingredients in AVELOX at the end of this Medication Guide.
