Donnatal

Donnatal is a prescription medication used primarily for the treatment of irritable bowel syndrome (IBS) and acute enterocolitis. It is a combination drug that contains phenobarbital, hyoscyamine, atropine, and scopolamine. These components work together to relieve symptoms such as cramping, abdominal pain, and diarrhea.
