Description

Lansoprazole, clarithromycin, and amoxicillin are used to treat and prevent the return of ulcers (sores in the lining of the stomach or intestine) caused by a certain type of bacteria (H. pylori). Lansoprazole is in a class of medications called proton pump inhibitors. Clarithromycin and amoxicillin are in a class of medications called antibiotics. Lansoprazole works by decreasing the amount of acid made in the stomach. Clarithromycin and amoxicillin work by stopping the growth of the bacteria that may cause ulcers. Antibiotics will not work for colds, flu, or other viral infections.
