Promethazine with DM - Does this medicine cause constipation?

I don't think this med causes constipation. I have been on Promethazine, 25mg, 4 times a day for many years due to problems with Crohns Disease. Vomiting can be a problem with Crohns patients. In the 10+ yrs I have been on it, I can never blame constipation on it. This is strictly from a personal point of view and use. We all know meds can affect different people differently, but I think it is highly unlikely this is the source of your problem. Best wishes, ChelleKay

Yes this medication often causes constipation along with dry mouth. Those two go hand in hand with this medication. Make sure you are drinking water. free discount card
