Diagnosed with APS some 9 years ago, put on Warfarin and self test with target INR 3.0 to 4.0 (ideally 3.5). Have been on 8mg / 9mg daily until earlier this year then had to reduce to 7mg / 8mg to prevent going over 4.0. Warfarin Clinic did test my blood and checked my meter against theirs meter, all OK. However, have now had to reduce further to 6mg/7mg to keep my INR around the 3.6 mark.
Has anyone experienced anything like this?
My lifestyle hasn't changed that much over the years and doing everything basically the same. The only difference being the Astra Zeneca shots earlier this year in January and April. Don't think this has had any effect, maybe its a reaction for being on Warfarin for such along time. Be grateful to hear if anyone else has had similar experience and if so any idea as to the cause
Have a Consultants telephone appointment later this month and will ask the question, but though I'd raise it here in case anyone else has had a similar experience.
