Drug Interaction Report

Using atazanavir together with vonoprazan is not recommended. By reducing stomach acid, vonoprazan can decrease the absorption and blood levels of atazanavir and make the medication less effective against HIV. Your doctor or pharmacist may be able to offer suggestions on safer alternatives if you require treatment for stomach acid or ulcer while you are being treated with atazanavir. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Food can enhance the levels of atazanavir in your body. To ensure maximal oral absorption, atazanavir should be administered with or immediately after a meal. This will make it easier for your body to absorb the medication.
