pulmonary embolism
"Multiple Bilateral P.E's at the age of 33. Needed a  medicine for life. Tried clexene,  couldn't face a needle daily that would create scar tissue beneath the surface. Warfarin was impractical due to weekly Dr. Visits to check INR, coupled with my yo yo ing INR. Having to duck out of work for weekly bloods was a pain. Rivoroxyban was next in the list, hair loss kicked in 3 months in. I also read an article highlighting the fact that people suffer for taking it at the rate of one life a week. I have settled for the last option available - Apixaban.  3 months in, hair loss returns. It's due to the blood not reaching the hair follicles apparently?  This creates a really dry scalp and hair loss. Still it keeps me alive."
