prescribed coumadin and plavix
by beachrox, Apr 29, 2008 10:58AM
I have been on Coumadin for 18 years due to Lupus Anticoagulant (Antiphospholipid Syndrome) and several DVTs. In 2005 had MI with occlusion of the LAD artery and had drug stent inserted and I am still on plavix. My doc has debated when to take me off the Plavix safely....what are the recent studies about this dilemma? thanks so much!

DRUG INTERACTIONS with Plavix (clopidogrel):
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). Accordingly, Plavix may interfere with the metabolism of phenytoin, tamoxifen, tolbutamide, warfarin, torsemide, fluvastatin, and many non-steroidal anti-inflammatory agents, but there are no data with which to predict the magnitude of these interactions. Caution should be used when any of these drugs is co administered with Plavix.
Best of luck,
Jack
