question: I have been on Pradaxa for about two years. For the past six weeks my lower abdomen aches and my bladder has gone into hype-drive. It has always been somewhat frequent even before i started taking a diruerectic. Now it s worse. My GP said I have diverticulitis and prescribed anti-biotics. This did not have any effect. I didn t take my prodaxa this morning and it has already eased up somewhat. Could the Pradaxa be causing this?
