AIDS Home > Atripla Drug Interactions

If you take diltiazem, warfarin, or certain seizure medications with Atripla, drug interactions may occur. These potentially negative interactions may interfere with the kidneys' ability to remove Atripla from the blood, which could lead to increased blood levels of Atripla and increased risk of side effects. Other medicines that can cause Atripla drug interactions include atazanavir, pimozide, hormonal contraceptives, and statins.
