Avatar n tn Warfarin (coumadin): Because of the increased risk of bleeding, the concomitant administration of Warfarin with Plavix should be undertaken with caution. (See PRECAUTIONS - General.) At high concentrations in vitro, clopidogrel inhibits P450 (C).
Avatar n tn To date there have been no reports of an important interaction in humans between warfarin and clopidogrel. Nonetheless, because warfarin increases the risk of bleeding, blood tests to measure the degree to which the blood is anti-coagulated or thinned (prothrombin time; INR) may be ordered to assess the degree of blood-thinning when warfarin and clopidogrel are used together.
Avatar m tn These visits come with their co-pays and deductibles too! Not to mention that warfarin has significant risks, drug interactions, food restrictions etc. And overall: you have to think of the worse case senario of switching to warfarin having the warfarin be too strong and your wife getting a bleed of some kind. This could be in her GI track, brain etc. and can be very life-threatening and could cause huge hospital bills.

The half-life of R-warfarin ranges from 37 to 89 hours, while that of S-warfarin ranges from 21 to 43 hours. Studies with radiolabeled drug have demonstrated that up to 92% of the orally administered dose is recov-ered in urine. Very little warfarin is excreted unchanged in urine.
Avatar m tn Coumadin is known for having many drug-drug and drug-food interactions, which can make you over or under coagulated. For instance, since it works by being a vitamin K antagonist, foods that contain vitamin K (like leafy greens) can lower your INR. Taking vitamin E or fish oil or aspirin could raise it, and make bleeding more likely.
Avatar f tn Loading doses of warfarin are not warranted and may result in bleeding complications. Interactions with other drugs must be considered, and therapy in elderly patients requires careful management. Current dosing recommendations are reviewed, and practical guidelines for the optimal use of warfarin are provided". Hope this helps, and if you have any further questions or comments you are welcome to respond. Thanks for your question. Take care.
