Bentyl is primarily prescribed to treat irritable bowel syndrome (IBS) in adults, helping to reduce abdominal pain, cramping, bloating, and intestinal spasms. It may also be used for other conditions involving smooth muscle spasms of the gastrointestinal tract.
Bentyl contains dicyclomine, an anticholinergic agent that blocks the action of acetylcholine on smooth muscle cells in the intestinal walls. This causes the muscles to relax, reducing painful contractions and spasms that cause IBS symptoms.
Bentyl may cause drowsiness, dry mouth, blurred vision, and constipation. It should be avoided in patients with certain conditions including glaucoma, urinary retention, or severe ulcerative colitis. Always take as directed and inform your doctor of all medications being taken to avoid interactions.
