Omeprazole, amoxicillin, and rifabutin

Generic name: Omeprazole, Amoxicillin, And Rifabutin
Drug class: H. pylori eradication agents

Usage of Omeprazole, amoxicillin, and rifabutin

Talicia® is a product containing three components: omeprazole, amoxicillin, and rifabutin. This medicine is used to treat patients with H. pylori infection.

Omeprazole is a proton pump inhibitor (PPI). It works by decreasing the amount of acid produced by the stomach. Amoxicillin and rifabutin 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.
