O General Information and Indications:
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.
O Information For Users:
Hyoscyamine comes as a tablet, an extended-release
(long-acting) capsule, a liquid to take by mouth, and in an injectable form.
The tablets and liquid are usually taken three or four times a day. The
extended-release capsules are usually taken twice a day. Do not crush, chew,
or divide the extended-release capsules. Hyoscyamine injections are given by
qualified health care professionals. Follow the directions on your
prescription label, ask your doctor or pharmacist If you have any questions.
Take hyoscyamine exactly as directed. Do not take more or less of it or take
it more often than prescribed by your health care provider.
Hyoscyamine controls symptoms associated with disorders of the GI tract, but
it does not cure the disorders. Continue taking hyoscyamine even if you feel
well. Do not discontinue taking hyoscyamine without informing your doctor.
