pulmonary embolism
"Had a Pulmonary Embolism in March 2014, I am happy with Xarelto in that it is a pill I can take without weekly blood work.  My only complaint is that I am losing my hair in clumps!  I tell you it is like I am taking chemo or something.  I used to have very thick long hair and now my hair falls out horribly in the shower, when I brush it, all day long on my clothes, in the car whatever. Hair loss is not currently listed as a side affect but I called the 800 number of the company and put in a complaint about it as many others have."
