Levsin (hyoscyamine) produces many effects in the body, including relief from muscle spasms.

Levsin also reduces the fluid secretions of many organs and glands in the body, such as the stomach, pancreas, lungs, saliva glands, sweat glands, and nasal passages.

Levsin is used to treat many different stomach and intestinal disorders, including peptic ulcer and irritable bowel syndrome. It is also used to control muscle spasms in the bladder, kidneys, or digestive tract, and to reduce stomach acid. This medicine is sometimes used to reduce tremors and rigid muscles in people with symptoms of Parkinson's disease.

Levsin is also used as a drying agent to control excessive salivation, runny nose, or excessive sweating.
