pulmonary embolism
"I'm on anti-coagulants permanently, previously on Warfarin without symptoms for three years before trying Pradaxa.  I have chronic gastritis, GORD, plus average 2-3 episodes of intestinal tract infections per year due to diverticulosis.
I tried Pradaxa 110mg twice daily for two weeks with bad symptoms developing after three days and becoming progressively worse.  Feeling unwell, tired, acid reflux, indigestion, upper abdominal ache and pain, bloating, belching, farting, diarrhoea, loose stools, and lastly, constipation in a person who has always been as regular as clockwork.
I took Pradaxa with food and 500mls of water and 20ml of antacid.  Bad move.  Back to Warfarin."
