Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

Some products that may interact with this drug include: "blood thinners" (such as warfarin, heparin, rivaroxaban, clopidogrel, ticlopidine), mifepristone.

Check all prescription and nonprescription medicine labels carefully since many contain pain relievers/fever reducers (NSAIDs such as aspirin, ibuprofen, naproxen, ketorolac) that may increase your risk for side effects if taken together with this medication. However, if your doctor has told you to take low-dose aspirin to prevent heart attack or stroke (usually 81-162 milligrams a day), you should keep taking the aspirin unless your doctor tells you not to. Ask your doctor or pharmacist for more details.

This medication may interfere with certain lab tests (such as prothrombin time/INR, factor Xa levels), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.
