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.
Hyoscyamine comes as a tablet, an extended-release (long-acting) capsule, and a liquid to take by mouth. The tablets and liquid are usually taken three or four times a day. The extended-release capsules are usually taken twice a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take hyoscyamine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release tablets whole; do not split, chew, or crush them.
Hyoscyamine controls symptoms associated with disorders of the GI tract, but it does not cure the disorders. Continue to take hyoscyamine even if you feel well. Do not stop taking hyoscyamine without talking to your doctor.
This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.
