Prevpac Drug Center

Medical Editor: John P. Cunha, DO, FACOEP

Prevpac (lansoprazole, amoxicillin and clarithromycin) is used to prevent stomach ulcer caused by infection with Helicobacter pylori (H. pylori). It is a combination of lansoprazole (Prevacid), a proton pump inhibitor (PPI), amoxicillin, a penicillin antibiotic, and clarithromycin, a macrolide antibiotic. Common side effects include diarrhea, headache, nausea, vomiting, and abnormal taste.

The recommended adult oral dose is 30 mg lansoprazole (Prevacid), 1 g amoxicillin, and 500 mg clarithromycin administered together twice daily (morning and evening) for 10 or 14 days. Prevpac may interact with HIV/AIDS medications, blood thinners, clopidogrel, cyclosporine, digoxin, iron supplements, fluconazole or ketoconazole, probenecid, rifabutin, sildenafil, tacrolimus, theophylline, sulfa drugs, cholesterol-lowering medicines, heart rhythm medications, sedatives, seizure medications, or tetracycline antibiotics. Tell your doctor all prescription and over-the-counter medications and supplements you use. During pregnancy, Prevpac should be used only when prescribed. Amoxicillin passes into breast milk. It is unknown if lansoprazole or clarithromycin pass into breast milk. Consult your doctor before breast-feeding.
