My INR has been steady for about 6 weeks now. WAsn't supposed to get checked again until a week from tomorrow.. but I've been having some stomach "issues" over the past few (4-5) days so I knew I should get checked. Went to the coum. clinic today and knew something was wrong when there was no blood from the finger stick site. My INR is 1.4 so the coumadin mgr. consulted with one of the cardio's and they put me on the shots. I just had one (could not do myself, made my poor hubby who had a vasectomy this morning do it!) and will give myself another in 12 hrs.. also she doubled my warfarin dose for tonight, and I get checked again tomorrow morning. I really got scared when she told me how low it was.. I like her because she is very matter-of-fact about the risk of haivng a mech. MV, but she also reassured me by showing me some study which said if you were on nothing for 4-5 days that the chance of a clot forming is so slim. Of course I am still a little freaked out about the whole thing. She said usually w/digestive issues you see a rise in INR but my warfarin must not be absorbing at all. Just wondering if anyone else had to do anything like this at some point and how quickly does it take INR to rise with the shots?
