I am a 78 yr olf female who was in hospital for 2 months, had 2 bowel surgeries and blood clots in the lung. I cant seem to get my INR level right  It was 2.0 when I came home 2 mos ago but has fluctuated between 1.0 and 7.5 but I think the 7.5 was due to a sulpha antiboitic for my incision. right now it is 1.2 and has been here for 2 weeks although I have been taking 6-7-8-9 mg of warfarin daily. I wonder if it could be a reacting with my Life Brand Spectrum Vitamin pill (gold) which I start on the advice of my surgeon 2 1/2 weeks ago?
Hello and welcome to Chat Doctor, Vitamin pills will not affect the INR value. If your INR value is fluctuating you need to consult your treating doctor to review the dose of warfarin. The INR value is controlled by doses of warfarin. The INR should be below 2.5 in patients who are on warfarin. Value of 7.5 is very high and requires urgent consultation with you treating doctor. Thanks and take care Chat Doctor.
