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 are: mifepristone, other drugs that can cause bleeding/bruising (including antiplatelet drugs such as clopidogrel, NSAIDs such as ibuprofen/naproxen, "blood thinners" such as warfarin/enoxaparin), certain antidepressants (including SSRIs such as fluoxetine, SNRIs such as desvenlafaxine/venlafaxine).

Other medications can affect the removal of rivaroxaban from your body, which may affect how rivaroxaban works. Examples include cobicistat, dronedarone, ritonavir, certain azole antifungals (itraconazole, ketoconazole, posaconazole), HIV protease inhibitors (such as lopinavir), rifamycins (such as rifampin), St. John's wort, drugs used to treat seizures (such as carbamazepine, phenytoin, phenobarbital), among others.

Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as ibuprofen or naproxen) that may increase your risk for bleeding 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 at dosages of 75-100 milligrams a day), you should keep taking the aspirin unless your doctor tells you not to. Ask your doctor or pharmacist for more details.
