Can Warfarin stop working if someone has taken it for 13+ years and every time he good to have his blood taken he gets a call from his doctor and told not to take it because his blood is to thin. He is 70 diabetic and overweight, but he has also lost 70 lbs in tin the last 6 months. Thank you for any answers

If your inr is to highthe warfarin is working too well.if you have lost 70lbs your body mass is reduced you will need less warfarin.also as you get older you will be less active and your metabolisim will slow down .so needing a lower dose

I have been on warfarin for 43 years my weight has been constant.73kilo.but now i am 70 years old i am less active.so my dose has reduced from 6mg to 2.5mg with an inr range of 3 to 4.5 and a target of 3.5

I have taken warfarin for about 30 years now and it was only after my 3rd heart ablation that my INR became relatively stable. There are many reasons why one's INR can become unstable or change unusually. If you are worried I would ask your hospital haematologist or anticoagulation nurse if they could help explain the blood situation. Take care. Annel

Yes I haven't made any lifestyle changes and I had to change to xarelto because my INR stopped stabilizing normally after 6 years of being fine on the warfarin. Wishing you all the best!
