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