I am an 81 year old male. I had hip replacement surgery 6 weeks ago. I came home on warfarin therapy. I took 7.5 mgs per day, and had visiting nurse check the levels of warfarin. I have been taken off warfarin for 2 days, and during the night, I had a nosebleed. It bled quite a bit, but did stop on its own after about 5 minutes. Should I continue aspirin therapy as I was told by orthopedic surgeon. I was told to take 4-n 81 mg aspirin for 4 days. I was on day 2 when the nosebleed occurred.
