default
Posted on Sun, 8 Dec 2013
Question: I had surgery on August 16 for endocarditis and started warfarin immediately. Could you please give me the side effects of warfarin? I have two questions: I have been taking 6-8 mg of warfarin daily for three months. What are the typical side effects of this drum and dosage? I have been instructed by my cardiologist to stop taking warfarin on November 14. How long should I expect until the side effects are gone? THANKS XXXXX
