Biaxin XL


Biaxin XL

Generic name: ClarithromycinBrand names: Biaxin XL, Biaxin

Why is Biaxin XL prescribed?

Biaxin, an antibiotic chemically related to erythromycin, is used to treat certain bacterial infections of the respiratory tract, including:

Strep throatPneumoniaSinusitis (inflamed sinuses)Tonsillitis (inflamed tonsils)Acute middle ear infectionsAcute flare-ups of chronic bronchitis (inflamed airways)

Biaxin is also prescribed to treat infections of the skin. Combined with other medications, it is used to treat ulcers near the exit from the stomach (duodenal ulcers) caused by H. pylori bacteria. It can also be prescribed to combat Mycobacterium avium infections in people with AIDS.

Biaxin is available in tablet and suspension form, and in extended-release tablets (Biaxin XL). The extended-release form is used only for sinus inflammation and flare-ups of bronchitis.

Most important fact about Biaxin XL

Biaxin, like any other antibiotic, works best when there is a constant amount of drug in the blood. To keep the amount constant, try not to miss any doses.

How should you take Biaxin XL?

You may take Biaxin suspension or tablets with or without food. Biaxin XL, however, should always be taken with food. Do not chew or crush Biaxin XL tablets. Shake Biaxin suspension before each dose and use it within 14 days.

Take the medication exactly as prescribed, and be sure to continue taking it for the full course of treatment.

  • If you miss a dose...Take it as soon as you remember. If it is almost time for your next dose, take the one you missed and take the next one 5 to 6 hours later. Then go back to your regular schedule.
  • Storage instructions...Store at room temperature in a tightly closed container, away from light. Do not refrigerate the suspension.

What side effects may occur?

Side effects cannot be anticipated. If any side effects develop or change in intensity, tell your doctor immediately. Only your doctor can determine whether it is safe for you to continue taking Biaxin.

  • Side effects may include:Abdominal pain, abnormal taste, diarrhea, nausea, rash, vomiting

Side effects of Biaxin XL are generally milder than those of regular Biaxin. They may include diarrhea, abnormal taste, and nausea.

Why should Biaxin XL not be prescribed?

Do not take Biaxin if you have ever had an allergic reaction to it, or if you are sensitive to it or erythromycin, or similar antibiotics such as azithromycin and troleandomycin. Also avoid Biaxin if you have a heart condition or an imbalance in the body's water and minerals; and do not take the drug while taking pimozide or terfenadine.

Special warnings about Biaxin XL

If you have severe kidney disease, the doctor may need to prescribe a smaller dose of Biaxin. Make sure the doctor is aware of any kidney problems you may have, since Biaxin could cause kidney inflammation.

Like other antibiotics, Biaxin may cause a potentially life-threatening form of diarrhea that signals a condition called pseudomembranous colitis (inflammation of the large intestine). Mild diarrhea, a fairly common Biaxin side effect, may disappear as your body gets used to the drug. However, if Biaxin gives you prolonged or severe diarrhea, stop taking the drug and call your doctor immediately.

Possible food and drug interactions when taking Biaxin XL

If Biaxin is taken with certain other drugs, the effects of either can be increased, decreased, or altered. It is especially important to check with your doctor before combining Biaxin with the following:

AlprazolamBlood thinners such as warfarinBromocriptineCarbamazepineCholesterol-lowering drugs such as lovastatin and simvastatinCilostazolColchicineCyclosporineDigoxinDisopyramideErgot-based migraine drugs such as ergotamine tartrate, and methysergide,FluconazoleHexobarbitalMethylprednisoloneMidazolamPhenytoinQuinidinePimozideRifabutinRitonavirSildenafilTacrolimusTheophyllineTriazolamValproateZidovudine

Special information if you are pregnant or breastfeeding

If you are pregnant or plan to become pregnant, notify your doctor immediately.

Biaxin may appear in breast milk, as does its chemical cousin, erythromycin.
