Blood Home > Arixtra Drug Interactions
Additional Information and Notable ExceptionsArixtra does not interact with vitamin K or foods rich in vitamin K. People often mistakenly assume that it does, as warfarin (Coumadin®, Jantoven®), an oral anticoagulant, interacts with vitamin K. Of course, you must still follow the usual dietary restrictions if you are taking warfarin and Arixtra together. However, if you are taking just Arixtra, there are no dietary restrictions.
Arixtra does not interact with acetaminophen (Tylenol®). Therefore, acetaminophen is usually the preferred over-the-counter pain or fever medication for people on Arixtra.
It should be noted that herbal medications might interact unpredictably with Arixtra, perhaps increasing the risk of bleeding or possibly making Arixtra less effective. Therefore, check with your healthcare provider before combining any herbal medication with Arixtra.
