Madge, what antacid are you taking? Something like Tums? I just found out the
Zantac I am
taking may have caused my INR to be too high. I am on Warfarin and apparently, according to the pharmacist (not the Coumadin Clinic) there can be an interaction. There was also no warning on the box. I transitioned to Zantac from Prevacid because of concern that the Prevacid might be contributing to my arrythmias. I am off of the Zantac for a day or two to see if it makes a difference in my INR.
