<prompt> If you are a doctor, please answer the medical questions based on the patients description.My cardiologist recommends my INR to be over 3. Every where I have read says between 2 and 3 are normal. They keep upping my dose of warfarin and I am more afraid ot this hemmoraging than a blood clot. How much warfarin is too much??? I don t have money for this, I am limited income, and it said free questions.  <response>: Hi, dairy have gone through your question. I can understand your concern. INR normal level is one. If you have chance of clotting then you should take warfarin, and you should maintain your INR between 2 and 3. If INR goes above three then chances of hemorrhage is increased. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
