Hi, I recently came out of surgery and was given heparin injections (came off warfarin in advance of the surgery). I am now being bridged back to warfarin. I'm injecting 15,000 single doses of heparin while "reloading" my warfarin. The warfarin dosage is 12 mg. I have to do this for 3 days, and then cut the warfarin to 10 mg until I hit my target INR. On the fourth day I am supposed to inject 5,000 units of heparin and so on till I've reached my target INR. I trust my haematologist completely but am nervous that 15,000 of heparin plus 12 mg warfarin is a lot. Any thoughts?
