In brief: Yes

Alcohol is contraindicated if you are on Coumadin (warfarin)! it increases the metabolism of coumadin, requiring more Coumadin to get the same inr, and lowering the inr if you stay on the same dose.
It also irritates the stomach and can cause bleeding, lowers platelet cells which increases the chance of serious bleeding. Talk to the doctor prescribing your Coumadin about stopping alcohol.
