Warfarin (Coumadin), a prescription drug used to prevent blood clots, saves countless lives. However, many drugs and supplements (even common pain medicines like aspirin and ibuprofen) can intensify its anti-clotting effect and put patients at risk of excessive bleeding. When Coumadin therapy is indicated, give your doctor—and your pharmacist—a comprehensive list of your prescription drugs, over-the-counter medicines, and herbal and dietary supplements, including vitamins. At each medical and dental visit, be certain the health care provider is aware that you are on Coumadin. As an extra precaution, also ask the pharmacist to double-check for any drug interactions when filling new prescriptions or picking up refills. Never stop taking Coumadin without first talking to your doctor.
