I'm on Bentyl for Irritable Bowel le Bowel Syndrome and that's an anti spasmotic.I take Viibryd and Klonopin for anxiety and depression and Protonix for GERD.The Pharmacist said it shouldn't constipate me if I take Perphenazine and Bentyl but I noticed a slight change in my bowel (stools are now normal but I don't go as much) when I started Perphenazine.Before that I was having loose bowels and needed to take loperamide but I stopped that.Any thoughts?Thanks,Mo
