Patient Education

Hyoscyamine


Hyoscyamine is used to control symptoms associated with disorders of the gastrointestinal (GI) tract. It works by decreasing the motion of the stomach and intestines and the secretion of stomach fluids, including acid. Hyoscyamine is also used in the treatment of bladder spasms, peptic ulcer disease, diverticulitis, colic, irritable bowel syndrome, cystitis, and pancreatitis. Hyoscyamine may also be used to treat certain heart conditions, to control the symptoms of Parkinson's disease and rhinitis (runny nose), and to reduce excess saliva production.
