I was placed on Warfarin about 4 weeks ago following a major fracture of the femur and subsequent hip replacement surgery. I was told that several small clots were seen in my lungs and that was the reason. I had already been taking fish oil caps 3x daily plus carvidilol and many other over the counter supplements. I was sure the list of my supplements was available before the surgery and I m wondering if none of those supplements were considered for possible interaction. I also take gabapentin 3x daily and omeprazole 1x.
