I must apologize in advance this is a personal subject and very embarrassing to me. My exalgo er 16mg tablets are hydromorphone, an opiate based medication it should dissolve completely over the course of 24 hours. So this is embarrassing for me im not very upended about this subject but I have no choice. I'm not very good with bowel movements but I have constant constipation this last month is been a little better but all the sudden for a week it stopped again. Anyways im freaking out a little because I had a bowel movement tonight that was a ball and it looked like it had something round in it in multiple areas. It scared me so I got a pair of gloves out of a box of hair dye and there were 3 FULL exalgo pills in there stuck and at least one broken. I have never ever misused it, I always take one pill every day in the morning. If they aren't being dissolved like they should be for whatever reason maybe my digestive system or something but that means I'm not being dosed properly but more importantly if they are stuck in my bowel out not dissolving then one day my bowel moves and they dissolve I'm could get 2 or 3 dosage of pills in one shot. Im thinking that will be very bad. The only med it could be is the Exalgo because it is the ONLY pill I take shaped that way. So now I'm scared to take it, I know it is not the type of medication you can just stop but I do not want to take it anymore. I am scared to death there is more stuck in my body that could just dissolve and make me sick or worse. Please if anyone has information that is calming to me until I see my pain specialist in a few weeks please advise me. Again I'm sorry for the graphicness of the subject.
