my husband thought he was having a gallbladder attack so we drove for an hour to get to the ER last saturday nite we have been in the hospital for 8 days. The ER doc suspected blood clots and was right, it has very scary this whole ordeal. They have stabilized him where he is in not much pain now. Upon doing tests they think that he has a rare genetic clotting disorder (anti thromblin 3 deficiency). They are trying to give him coumadin to bring up his INR level so he can go home, first 3 days 5 mg coumadin INR level 1.1, 4th day 7.5 mg coumadin still INR level 1.1, 5th day 10mg coumadin INR level went up to 1.3, 6th day 15 mg coumadin INR level only at 1.5. They want to get his INR level between 2.5 qnd 3.0 I am concerned about the amount of coumadin given to him and the levels not going up. I was wondering if anyone else has had a similar expierence. We are so lucky that we made it to the ER in time.
