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 (such as the 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.
Dizziness, drowsiness, blurred vision, dry mouth, headache, trouble sleeping, constipation, flushing, dry skin, and decreased sweating may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water or use a saliva substitute. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects.

Tell your doctor right away if any of these unlikely but serious side effects occur: mental/mood changes (e.g., confusion, unusual excitement), fast/irregular heartbeat, difficulty urinating, decreased sexual ability, loss of coordination, trouble speaking, vomiting. Get medical help right away if you have any very serious side effects, including: eye pain/swelling/redness, vision changes (such as seeing rainbows around lights at night).
