Claripen (Clarithromycin)

Claripen is a semi-synthetic macrolide antibiotic chemically related to erythromycin and azithromycin (Zithromax). It is effective against a wide variety of bacteria, such as Haemophilus influenzae, Streptococcus pneumoniae, Mycoplasma pneumoniae, Staphylococcus aureus, and mycobacterium avium, and many others. Like all macrolide antibiotics, Claripen prevents bacteria from growing by interfering with their ability to make proteins. Due to the differences in the way proteins are made in bacteria and humans, the macrolide antibiotics do not interfere with production of proteins in humans. The FDA approved Claripen in October 1991.

Claripen comes as a tablet, an extended-release (long-acting) tablet, and a suspension (liquid) to take by mouth. The regular tablet and liquid are usually taken with or without food every 8 (three times a day) to 12 hours (twice a day) for 7 to 14 days. The extended-release tablet is usually taken with food every 24 hours (once a day) for 7 to 14 days. Your doctor may tell you to take Claripen for a longer time depending on your condition. Take Claripen at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Claripen exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Shake the suspension well before each use to mix the medication evenly.

Swallow the long-acting tablets whole; do not split, chew, or crush them.

You should begin to feel better during the first few days of treatment with Claripen. If your symptoms do not improve or get worse, call your doctor.

Take Claripen until you finish the prescription, even if you feel better. If you stop taking Claripen too soon, or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
