What Exactly Is Dicyclomine?

Dicyclomine is a specialized medicine that relaxes the muscles in your gut and stomach. By doing this, it stops uncomfortable spasms and sharp cramps from hurting you. Doctors often use it for a common condition called Irritable Bowel Syndrome (IBS) that causes belly pain.

To put it simply, this drug belongs to a group of medicines called antispasmodics. That means it prevents muscles from squeezing too tightly when they should stay calm. Relaxing these gut muscles gives your stomach fast and lasting relief from painful cramps.

  • Adults Over 65: Older adults are more sensitive to this medicine's side effects. Doctors usually prescribe a much lower dose for safety.

Because medical staff give this injection in a clinic, accidental overdose is rare. However, if you suspect someone received too much medicine, get emergency help right away.
