INR too low?

I have had a DTV for 2 1/2 months now. My INR has never been over 2, it has stayed at 1.99 and my last check was at 1.49 and they said that was fine. My leg still hurts so I would assume the clot is not gone. In the beginning I was told I needed to stay between a 2-2.5. Does this sound strange to anyone?

The part that sounds strange is that your INR is 1.49 and they said it is ok. Most doctors want your INR between 2.0-3.0 if you have a DVT, unless you have contraindications (pregnant, medical condition, etc).

Has the doctor been changing your dosage to try and keep you between 2-3? How often do you have your blood checked? Also, make sure you are not eating too many foods with high amounts of vitamin K. Here is a very helpful chart: http://www.drgourmet.com/md/warfarincomprehensive.pdf

hi ive had my dvt since easter, my leg still gets sore and my INR levels go up and down, im not a doctor, but if you are having INR checked often with blood tests then i wouldnet worry to much, the pain has gotten slightly better over time, it also depends how much damage was done to your veins, just be positive. and take it easy

I was getting my blood checked every week but now I'm every two weeks. I take 7.5mg of warfarin a day and my INR levels stay about the same. He said that since my PT is almost 15 seconds I'm good. It's been hard but I have tried to cut out all of the high vit K foods (which has been hard) because I'm so worried that my INR is already so low. They weren't going to do any more scans but I've asked them to just for a piece of mind. Thanks for the encouragement. I'm really hoping that it will get better over time. Patience usually isn't one of my strong points.

They should probably get your INR up some. You just need to fine tune your coumadin intake. You should have several strengths available to do that (maybe 1mg, 3mg, 5mg, etc). You don't need to take the same amount every day. You may be 4mg every other day and 3mg in between. There is no correlation to your body size, etc to how much coumadin you need and it can be a pain to get it right. The pain is not an indicator if the clot is there or reabsorbed. Clots can inflame and injure the vein tissue and some people have symptoms for years. It is worth the trouble because a second clot may mean coumadin for life.
