Uses

This product is used to treat an infection caused by the bacteria H. pylori. This bacteria can cause stomach/intestinal ulcers and irritation/swelling of the lining of the stomach. It may also increase the risk of stomach cancer. Treating the infection will help the ulcers get better and reduces the risk of serious damage to the lining of the stomach/intestines (such as bleeding, tearing).Vonoprazan is an acid blocker. It works by blocking acid production in the stomach. Decreasing excess stomach acid can help ulcers heal. Amoxicillin is an antibiotic used to treat a wide variety of bacterial infections (including H. pylori). Treating the infection helps the ulcers heal and reduces the risk of ulcers returning. Amoxicillin is a penicillin-type antibiotic. It works by stopping the growth of bacteria. Amoxicillin treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.

A product that may interact with this drug is: methotrexate (especially high-dose treatment).
