Like A Pill

I've been taking these things for around two years now. I recently had a call with my oncologist and he asked what medication I'm on. I told him I'm on this and he asked why. I gave him the background (picc line, clot, blah blah blah) and he said you shouldn't be taking that now. To that end, I had an ultrasound today to check for clots and now I'm going to be able to stop taking it. Hoorah.
