When taken together, Lipitor and Warfarin can interact with each other in several ways. Lipitor can increase the levels of Warfarin in the blood, which can increase the risk of bleeding. This is because Lipitor can inhibit the enzyme that breaks down Warfarin, allowing more of the medication to stay in the body.
