Clarithromycin Basics

Antibiotics are some of the most frequently prescribed medications in the United States. Antibiotics fight diseases and infections by killing or preventing the spread of bacteria. Clarithromycin is one of over 100 variations of antibiotics available to be used for these purposes.

Identification

• According to Pub Med, a service of the National Institutes of Health, clarithromycin is used for the treatment of bacterial infections such as pneumonia, sinus infections and bronchitis. Clarithromycin is a macrolide antibiotic, which means it works by inhibiting the growth of new bacteria.

Medication Schedule

• Clarithromycin comes as a tablet that can be standard or long-acting. An oral liquid form is also available. The standard tablet, as well as the liquid, are generally taken twice a day on a full or empty stomach for one to two weeks. The long-acting tablet is taken for the one to two weeks as well; however, it is typically taken only once a day.

Risks and Side Effects

• According to WebMd.com, possible side effects of clarithromycin may include diarrhea, upset stomach, headaches or changes in taste. The Mayo Clinic states that clarithromycin should not be used in conjunction with astemizole, pimozide or other antidepressants, as serious cardiac side effects may occur. Ask your doctor or pharmacist for a complete list of medications that may interact with clarithromycin. If side effects are persistent or become worse over time, contact your health care provider.
