I had a pulmonary embolism a month ago . No idea what caused it really so put onto Warfarin for 6 months . My INR is stable on my current dose . This week I had a colonoscopy and had to stop the pills for 5 days before and have clexane injections. My consultant has told me that I will have Clexane injections for another 2 days after the procedure and to re start the Warfarin as well. The anti coagulant clinic of my local hospital says I should be continuing the clexane and Warfarin together until my next INR test on the 16 th July ( next Wednesday ) and insist that I will be leaving myself at risk of another embolism if I don't take both for this extra 4 days . I am seeing the consultant again tomorrow . Whose guidance do I follow ?? Anyone know about this please ? I have been sick with worry for weeks now ... embolism then possible bowel cancer ( it isn't by the way ... some good news at last !) so this is another worry I could do without . Please can anyone help ??
