## Uses for omeprazole, amoxicillin, and rifabutin

Talicia® is a product containing three components: omeprazole, amoxicillin, and rifabutin. Omeprazole, amoxicillin, and rifabutin 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, omeprazole, amoxicillin, and rifabutin will not work for colds, flu, or other virus infections.

Omeprazole, amoxicillin, and rifabutin is available only with your doctor's prescription.

## Before using omeprazole, amoxicillin, and rifabutin

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For omeprazole, amoxicillin, and rifabutin, the following should be considered:

### Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to omeprazole, amoxicillin, and rifabutin or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.
