The dose that works.: There is no exact upper limit to Coumadin (warfarin) although the most I have seen someone need is about 12mg daily. Because Coumadin (warfarin) is so closely monitored with blood tests the right answer is the limit is the dose that gets you to your goal inr. Some people are genetically "coumadin resistant" and need much higher doses and people with high vitamin k diets also need higher doses.

Dr. Luke Hermann answered

Yes: An occaisional beer should not be an issue for patients taking coumadin (warfarin). Excessive alcohol consumption, which can lead to bleeding in the stomach and liver dysfunction should be avoided because these problems will be compounded by coumadin (warfarin).

Do the side effects of Coumadin (warfarin) build up over time? Are there long term side effects?
2 doctor answers • 3 doctors weighed in

Dr. Riga Pemba answered

Should not: Coumarin is take for certain medical problems and it works by thinning the blood to prevent blood clots. It works by inhibiting certain blood clotting factors. As soon as one stops taking the coumarin the blood regains it's usual clotting abilities. It usually takes about 48 to 72 hours to replenish these factors leaving no long term side effects.

Bleed: Coumadin (warfarin) is rat poison. It is used as an anticoagulant for certain medical conditions. The levels are closely monitored by your doc. Too much can thin you blood and could cause you to bleed and lose a lot of blood with its own consequences.
