Stacy Wiegman, PharmD, Pharmacy, answeredOver-the-counter anti-diarrheal medications come in two different forms: bismuth subsalicylate and loperamide. Bismuth subsalicylate helps to treat diarrhea by slowing the movements of fluids and electrolytes into the intestines. It also helps to decrease inflammation in the intestines and kills organisms that cause diarrhea. Loperamide helps to slow the movements in your bowels and discourage diarrhea.
