Levofloxacin (Page 16 of 16)

17.4 Drug Interactions with Insulin, Oral Hypoglycemic Agents and Warfarin

Patients should be informed that if they are diabetic and are being treated with insulin or an oral hypoglycemic agent and a hypoglycemic reaction occurs, they should discontinue levofloxacin and consult a physician.

Patients should be informed that concurrent administration of warfarin and levofloxacin has been associated with increases of the International Normalized Ratio (INR) or prothrombin time and clinical episodes of bleeding. Patients should notify their physician if they are taking warfarin, be monitored for evidence of bleeding and also have their anticoagulation tests closely monitored while taking warfarin concomitantly.

17.5 FDA-Approved Medication Guide

MEDICATION GUIDE
LEVOFLOXACIN TABLETS
(lee” voe flox’ a sin)

Read the Medication Guide that comes with levofloxacin tablets 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 levofloxacin tablets?

Levofloxacin tablets belong to a class of antibiotics called fluoroquinolones. Levofloxacin tablets 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 levofloxacin tablets.

  1. Tendon rupture or swelling of the tendon (tendinitis).
    • Tendon problems can happen in people of all ages who take levofloxacin tablets. Tendons are tough cords of tissue that connect muscles to bones.
      • Some tendon problems 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 levofloxacin tablets 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 levofloxacin tablets. 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 levofloxacin tablets 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 levofloxacin tablets. 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 levofloxacin tablets. 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 that causes muscle weakness).

    Fluoroquinolones like levofloxacin tablets 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 levofloxacin tablets? ” for more information about side effects.

What are levofloxacin tablets?

Levofloxacin tablets are 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 levofloxacin tablets.

In children 6 months and older who have breathed the anthrax bacteria germ:

  • Levofloxacin tablets are used to prevent anthrax disease (inhalation anthrax).
  • It is not known if it is safe to use levofloxacin tablets in children for more than 14 days.

It is not known if levofloxacin tablets are safe and work 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 levofloxacin tablets, do not kill viruses.

Call your healthcare provider if you think your condition is not getting better while you are taking levofloxacin tablets.

Who should not take levofloxacin tablets?

Do not take levofloxacin tablets 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 levofloxacin tablets. Ask your healthcare provider if you are not sure. See the list of the ingredients in levofloxacin tablets at the end of this Medication Guide.

What should I tell my healthcare provider before taking levofloxacin tablets?

See “What is the most important information I should know about levofloxacin tablets?”. Tell your healthcare provider about all your medical conditions, including if you:

  • have tendon problems
  • have a disease that causes muscle weakness (myasthenia gravis)
  • 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 levofloxacin tablets 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 levofloxacin will harm your unborn child.
  • are breast-feeding or planning to breast-feed. Levofloxacin is thought to pass into breast milk. You and your healthcare provider should decide whether you will take levofloxacin tablets or breast-feed.

Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, herbal and dietary supplements. Levofloxacin tablets 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 levofloxacin tablets or other fluoroquinolones may increase your risk of central nervous system effects and seizures. See “What are the possible side effects of levofloxacin tablets?
  • 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 levofloxacin tablets?
  • 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 levofloxacin tablets? ”.
  • theophylline (Theo-24®† , Elixophyllin®† , Theochron®† , Uniphyl®† , Theolair®†)
  • Certain medicines may keep levofloxacin tablets from working correctly. Take levofloxacin tablets 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)

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 levofloxacin tablets?

  • Take levofloxacin tablets exactly as prescribed by your healthcare provider.
  • Take levofloxacin tablets at about the same time each day.
  • Drink plenty of fluids while taking levofloxacin tablets.
  • Levofloxacin tablets can be taken with or without food.
  • If you miss a dose of levofloxacin tablets, take it as soon as you remember. Do not take more than one dose in one day.
  • Do not skip any doses, or stop taking levofloxacin tablets 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 levofloxacin tablets? ”),
    • you have a serious allergic reaction (see “What are the possible side effects of levofloxacin tablets? ”), 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 levofloxacin. If this happens, levofloxacin tablets 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 levofloxacin tablets after being exposed to anthrax:

  • Levofloxacin tablets have 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 levofloxacin tablets exactly as prescribed by your healthcare provider. Do not stop taking levofloxacin tablets without talking with your healthcare provider. If you stop taking levofloxacin tablets too soon, it may not prevent you from getting the anthrax disease.
  • Side effects may happen while you are taking levofloxacin tablets. When taking levofloxacin tablets 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 levofloxacin tablets. It is not known if it is safe to use levofloxacin tablets 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 levofloxacin tablets, you and your healthcare provider should decide whether the benefits of taking levofloxacin tablets for anthrax are more important than the risks.

What should I avoid while taking levofloxacin tablets?

  • Levofloxacin tablets can make you feel dizzy and lightheaded. Do not drive, operate machinery or do other activities that require mental alertness or coordination until you know how levofloxacin tablets affect you.
  • Avoid sunlamps, tanning beds and try to limit your time in the sun. Levofloxacin tablets can make your skin sensitive to the sun (photosensitivity) and the light from sunlamps and tanning beds. You could get severe sunburn, blisters or swelling of your skin. If you get any of these symptoms while taking levofloxacin tablets, call your healthcare provider right away. You should use a sunscreen and wear a hat and clothes that cover your skin if you have to be in sunlight.

  • Skin rash

    Skin rash may happen in people taking levofloxacin tablets, even after only one dose. Stop taking levofloxacin tablets at the first sign of a skin rash and call your healthcare provider. Skin rash may be a sign of a more serious reaction to levofloxacin tablets.

  • Intestine infection (Pseudomembranous colitis)

    Pseudomembranous colitis can happen with most antibiotics, including levofloxacin tablets. Call your healthcare provider right away if you get watery diarrhea, diarrhea that does not go away or bloody stools. You may have stomach cramps and a fever. Pseudomembranous colitis can happen 2 or more months after you have finished your antibiotic.

  • Changes in sensation and possible nerve damage (Peripheral Neuropathy)

    Damage to the nerves in arms, hands, legs, or feet can happen in people taking fluoroquinolones, including levofloxacin tablets. Talk with your healthcare provider right away if you get any of the following symptoms of peripheral neuropathy in your arms, hands, legs, or feet:

    • pain
    • burning
    • tingling

The chances of this happening are higher in people:

    • 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)
  • Changes in blood sugar [low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia)]

    People who take levofloxacin tablets and other fluoroquinolone medicines with oral anti-diabetes medicines or with insulin can get low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia). Follow your healthcare provider’s instructions for how often to check your blood sugar. If you have diabetes and you get low blood sugar while taking levofloxacin tablets, stop taking levofloxacin tablets and call your healthcare provider right away. Your antibiotic medicine may need to be changed.
