Biaxin is a very effective antibiotic that is part of the medical community's macrolide antibiotic arsenal. Biaxin and Biaxin XL are the trade names for the generic drug Clarithromycin, and are only available by prescription.

Biaxin comes in a few different forms, including tablet and suspension form (liquid). Biaxin prescriptions are generally split into two daily doses taken twelve hours apart. The drug may be taken with or without food. Some things to note about taking the varying forms of Biaxin are:

• Biaxin is best taken with a full 8 ounces of water • Biaxin suspension should be shaken prior to each dose • Suspension should be accurately measured with a dosing cup, dropper, or dosing spoon that is clearly marked • Biaxin XL 500mg is the 'extended release' tablet form of the drug; these tablets should never be broken or crushed, as this disturbs the medication delivery system of the antibiotic • Biaxin XL should always be taken with food

Like most antibiotics, Biaxin may relieve symptoms associated with the infection before the entire dosage is completed. Infection may still be present, though, so patients should take the complete course of treatment.

Biaxin does have the potential to interact with a number of drugs and may affect the effectiveness of certain medications; likewise, the effectiveness of Biaxin may be affected by some medications. The treating physician should be told about all other medicines that are being taking (including OTC medications). A serious heart condition can result when Biaxin is taken with Terfenadine (Seldane), Pimozide (Orap), or Cisapride (Propulsid), so it is especially important to tell the doctor if these medicines are being used.

Biaxin xl 500 may be unsafe for patients who have liver or kidney disease. Biaxin may not be appropriate for these patients, or dosing may need to be monitored and/or the dosage lowered.

It is unclear if Biaxin is harmful to unborn or newborn babies. Pregnant or breastfeeding women should only take Biaxin after discussing the risks with their doctor.

As with all medications, the maximum effectiveness and safety of Biaxin use requires full disclosure to the treating physician regarding past and present medication use and medical history.

Patients should be aware that Biaxin does carry a risk for side effects and allergy, as all medications do. Any new or increased occurrence of symptoms and discomfort warrant a call to the doctor's office for further instruction.
