Uses for Triple Therapy

Prevpac® is a product containing three components: lansoprazole, amoxicillin, and clarithromycin. This medicine is used to treat patients with H. pylori infection and duodenal ulcers caused by H. pylori bacteria.

Lansoprazole is a proton pump inhibitor (PPI). It works by decreasing the amount of acid produced by the stomach. Amoxicillin and clarithromycin both belong to the class of medicines known as antibiotics. They work by killing bacteria or preventing their growth. However, this medicine will not work for colds, flu, or other virus infections.

This medicine is available only with your doctor's prescription.
