Warfarin Sodium and hives

I recently developed hives on warfarin, but I am sure it is an allergy. When I started taking benedryl they went away for awhile. That indicates allergy. I read on-line that they only have one case of someone being allergic to warfarin itself and many cases of allergies to the color and fillers. It is something to discuss with your doctor if you are having allergy indicators such as hives, swelling, joint swelling.

After one year of warfarin, I have developed hives

I have been on Coumadin for about 2 months now after surviving a cerebral sinus venous thrombosis (blood clot on my brain - akin to a stroke). I am s 34 yo female who races triathlons and leads a very active healthy lifestyle. My side effects seem to be mild compared to what I read of others. I am on 5mg/day, except 1 day a week I take 10mg. My INR has been pretty stable. The side effects I notice are mild forgetfulness which I am hoping goes away as I start my 3rd year of law school next week! I also had some weird skin peeling on my hands, but that has subsided. I seem to urinate more often than normal and soda pop tastes weird to me now. Anyone else experience the frequent urination and/or taste issues?
Thanks!

I have been on warfarin for about two weeks as blood clots were found in my lung. I would like to hear from others who have developed rash ( non itching) on arms and now legs. My doctor does not seem to think it is linked to the medication, but really there is no other explaination.
