Common use

Bentyl is primarily indicated for the treatment of irritable bowel syndrome (IBS) in adults. It is specifically used to relieve symptoms such as abdominal pain, cramping, and bowel spasms that characterize this functional gastrointestinal disorder. Healthcare providers may prescribe Bentyl for other off-label uses involving smooth muscle spasm relief in the gastrointestinal tract when clinically appropriate.

Dosage and direction

The recommended adult dosage is 20 mg four times daily. However, treatment typically begins with a lower dose (10-20 mg three or four times daily) to assess tolerance. The medication should be taken 30 minutes to one hour before meals and at bedtime for optimal effect. Dosage adjustments should only be made under medical supervision based on individual response and tolerance. Do not crush or chew tablets; swallow whole with water.

Precautions

Use with caution in patients with autonomic neuropathy, hepatic or renal disease. May cause drowsiness or blurred vision—avoid driving or operating machinery until effects are known. Elderly patients may be more sensitive to anticholinergic effects. Use during pregnancy only if clearly needed. Not recommended during breastfeeding. May decrease sweating, increasing risk of heat prostration in hot environments.

Antacids may reduce absorption. Alcohol may enhance drowsiness. Always inform your healthcare provider of all medications, including over-the-counter drugs and supplements.
