Hi Everyone, I had an endoscopy and a colonoscopy last Friday. I had been off my usual 7.5mg dose of warfarin for 5 days and was taking 80mg shots of Lovenox twice a day for 3 days before the procedures. Everything went fine. INR at procedure was 1.2. I started back on warfarin on Friday evening as well as the Lovenox and have continued both since that time. Protime at Dr yesterday was 1.5. Because I have 2 mechanical valves I need to stay between 3 and 4. The Dr. told me to up my warfarin by a half dose one day a week. I only have 2 shots of Lovenox left. I am worried about being this low for so long. What do you think? Does it usually take this long to get back to levels?
