How it works

Important information

You should not use this medicine if you have a life-threatening heart rhythm disorder, a history of Long QT syndrome, if you have ever had jaundice or liver problems caused by taking clarithromycin, or if you have liver or kidney disease and are also taking colchicine. Many other drugs can interact with clarithromycin. There are certain medicines that can cause life-threatening drug interactions with clarithromycin, and should not be used at the same time. Tell each of your healthcare providers about all medicines you use now, and any medicine you start or stop using. Take this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Clarithromycin will not treat a viral infection such as the common cold or flu.

How should I take clarithromycin?

Take clarithromycin exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended. You may take the tablets and oral suspension (liquid) with or without food. Clarithromycin extended-release tablets (Biaxin XL) should be taken with food. Do not crush, chew, or break an extended-release tablet. Swallow it whole. Shake the oral suspension (liquid) well just before you measure a dose.

Use this medicine for the full prescribed length of time. Clarithromycin is usually given for up to 7 to 14 days. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Clarithromycin will not treat a viral infection such as the flu or a common cold.
