... COuld this be related to my dosage of Warfarin? The dose was too high so the doctor reduced the dose from 5 mg to 4.5 but consulting with a friend who is a cardiologist and her son who is doing his clinical practicum after 5 years in pharmacolgy, they thought I should wean myself off Warfarin gradually . I am now taking only 1.5 and want to substitute Apsrin for it. Basically my question is, "Could the Warfarin overdosage over the lats ten years have caused the increase in the size of my intrahepatic hemagioma?"
