Hyoscyamine is used to treat a variety of
stomach/intestinal problems such as cramps and irritable bowel syndrome. It is
also used to treat other conditions such as bladder and bowel control problems,
cramping pain caused by kidney stones and gallstones, and Parkinson's disease.
In addition, it is used to decrease side effects of certain medications (drugs
used to treat myasthenia gravis) and insecticides.This medication works by decreasing acid production in the
stomach, slowing down the natural movements of the gut, and relaxing muscles in
many organs (e.g., stomach, intestines, bladder, kidney, gallbladder).
Hyoscyamine also lessens the amount of certain body fluids (e.g., saliva,
sweat). This medication belongs to a class of drugs known as
anticholinergics/antispasmodics.
