Prevpac
Generic name: Amoxicillin, clarithromycin, and lansoprazole

What is Prevpac?
Prevpac is a prepackaged combination of drugs designed to treat duodenal ulcers caused by Helicobacter pylori bacteria, the most common cause of ulcers. Prevpac is made up of 3 medications: amoxicillin and clarithromycin (Biaxin) are the antibiotic components and lansoprazole (Prevacid) is a proton-pump inhibitor that reduces the production of gastric acid.

What is the most important information I should know about Prevpac?
Take Prevpac exactly as prescribed and finish your entire course of therapy. If you stop too soon, the ulcer may not heal completely and your symptoms may return.

Serious and occasionally fatal allergic reactions have occurred in people taking antibiotics similar to those in Prevpac. Seek emergency medical treatment if you develop hives, swelling, itching, fainting, breathing difficulties, or chest pain. Also, if you develop severe diarrhea while taking Prevpac, call your doctor.

------------------------------------------------------------------------------

Who should not take Prevpac?
Prevpac therapy is not recommended if you have severe kidney disease. Use Prevpac with caution if you are over 65 years old.

Do not take Prevpac if you've ever had an allergic reaction to antibiotics such as amoxicillin, clarithromycin, erythromycin, or penicillin. Also, avoid Prevpac if you've had a reaction to any cephalosporin-type antibiotic.
