"i took for a week 100mg and had massive amounts of bleeding in my stools any urine. doctors first thought cancer but then saw i had just started this drug an took me off it straight-a-way. within 4 days, everything went back to normal and all my tests came back clear. frightened me something terrible. doctors say only happens in less then 1% but can cause major hemorrhaging. lost 10kg in one week. took me two month to recover properly with weekly follow up blood tests."
