deep vein thrombosis
"I was prescribed Xarelto when a blood clot developed after surgery for my broken leg.  I did not notice any immediate side effects until....  I normally have 3 day, semi-light periods and they went to 7-9 days of the worst ever.  I won't go into detail.  It also caused my iron level to drop to 17!  I stayed on Xarelto for 6 months and it worked for me.  I was told Xarelto won't dissolve your clot it just thins your blood enough to prevent the clot from growing or new clots, The existing clot is absorbed into the body.  I think my hair was falling out also but that may have been from the low iron?"
