Levsin

Hyoscyamine Sulfate Drug Information

• Levsin Overview

  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, Levsin is used to decrease side effects of certain medications (drugs used to treat myasthenia gravis) and insecticides. Levsin works by decreasing acid production in the stomach, slowing down the natural movements of the gut, and relaxing muscles in many organs (such as the stomach, intestines, bladder, kidney, gallbladder). Hyoscyamine also lessens the amount of certain body fluids (e.g., saliva, sweat). Levsin belongs to a class of drugs known as anticholinergics/antispasmodics.

• How to Use Levsin

Do not increase your dose or take it more often than prescribed without consulting your doctor. Adults and children 12 years and older should not take more than 1.5 milligrams in 24 hours. Children aged 2 to 12 years should not take more than 0.75 milligrams in 24 hours. Ask your doctor or pharmacist for more information. Antacids lower the absorption of hyoscyamine.
