<s>[INST] 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. [/INST] 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. </s>
