Can you take coumadin and Adderall together?

Yes, acetaminophen in LOWER doses can be used for a short time while taking coumadin. When you exceed 1300 mg a day, this modifies the INR and the action of coumadin..

However if you take acetaminophen every day at the same dosage (e.g. 2 Tylenol 500 mg 4 times a day) and did when the Coumadin was prescribed, then your Coumadin dosage has already been adjusted for this interaction (as long as you reported it to your doctor), and there is no problem in taking acetaminophen in this way. However, if you stop your acetaminophen daily use, you need to advise your doctor and take a blood test for INR 6-7 days later.
