I have been given 1ml syringes of Fragmin for use in emergency. My Consultant said to take it if my INR drops below 2.0. At the moment it's 2.7 and I feel awful. I have never taken the Fragmin as a bit nervous it may thin my blood too much whilst I'm trying to raise my INR. I feel so bad just now and it will take a few days for INR to rise again. My INR range is 3.5 to 4.5. Has anyone else taken Fragmin with a similar INR of 2.7 and been okay?
