FLOXIN®
[Flox in]
(ofloxacin)

Read the Medication Guide that comes with FLOXIN® (ofloxacin) 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 FLOXIN® (ofloxacin) ?

FLOXIN® (ofloxacin) belongs to a class of antibiotics called fluoroquinolones. FLOXIN® (ofloxacin) 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 FLOXIN® (ofloxacin) .

  • Tendon rupture or swelling of the tendon (tendinitis)
    • Tendons are the 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 FLOXIN® (ofloxacin) . The risk of getting tendon problems is higher if you:
    • 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 FLOXIN® (ofloxacin) 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 FLOXIN® (ofloxacin) . 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 FLOXIN® (ofloxacin) . 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
    • Worsening of myasthenia gravis (a disease that causes muscle weakness). Fluoroquinolones like FLOXIN® (ofloxacin) 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 FLOXIN® (ofloxacin) ?” for more information about side effects.

What is FLOXIN® (ofloxacin) ?

FLOXIN® (ofloxacin) is a fluoroquinolone antibiotic medicine used in adults to treat certain infections caused by certain germs called bacteria. It is not known if FLOXIN® (ofloxacin) is safe and works in people under 18 years of age. Children less than 18 years of age have a higher chance of getting bone, joint, or tendon (musculoskeletal) problems such as pain or swelling while taking FLOXIN® (ofloxacin) .

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 FLOXIN® (ofloxacin) do not kill viruses.

Call your healthcare provider if you think your condition is not getting better while you are taking FLOXIN® (ofloxacin) .

Who should not take FLOXIN® (ofloxacin) ?

Do not take FLOXIN® (ofloxacin) 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 FLOXIN® (ofloxacin) . Ask your healthcare provider if you are not sure. See the list of the ingredients in FLOXIN® (ofloxacin) at the end of this Medication Guide.

What should I tell my healthcare provider before taking FLOXIN® (ofloxacin) ?

See “What is the most important information I should know about FLOXIN® (ofloxacin) ?

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)

Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, herbal and dietary supplements. FLOXIN® (ofloxacin) 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 FLOXIN® (ofloxacin) or other fluoroquinolones may increase your risk of central nervous system effects and seizures. See “What are the possible side effects of FLOXIN® (ofloxacin) ?
  • theophylline
  • a blood thinner (warfarin, Coumadin, Jantoven)
  • an oral anti-diabetes medicine or insulin
  • a medicine to control your heart rate or rhythm (antiarrhythmics). See “What are the possible side effects of FLOXIN® (ofloxacin) ”.
  • 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 FLOXIN® (ofloxacin) ?”.
  • Certain medicines may keep FLOXIN® (ofloxacin) from working correctly. Take FLOXIN® (ofloxacin) either 2 hours before or 2 hours after taking these products:
    • an antacid, multivitamins, or other product that has calcium, magnesium, aluminum, iron, or zinc.
    • sulcrafate (Carafate)
