What Does Bentyl Do?

Bentyl is classified as ananticholinergicmedication because it reduces the effect of the neurotransmitter acetylcholine within the body.

This diminished action of acetylcholine results in a decrease in muscle spasms and secretion ofmucus.

Some drugs can cause severe interactions and/or side effects when taken with Bentyl.

The anticholinergic effect of Bentyl can affect smooth muscles throughout the body.

Bentyl may also cause more serious side effects, such as confusion, disorientation, and short-term memory loss.
