Introduction

Dicyclomine, a trusted antispasmodic medication, is commonly prescribed to treat intestinal and stomach-related conditions such as Irritable Bowel Syndrome (IBS).

What is Dicyclomine?

Dicyclomine hydrochloride is a medication that belongs to the class of anticholinergic and antispasmodic agents. It helps by relaxing the smooth muscles of the gastrointestinal (GI) tract, making it effective in reducing involuntary muscle contractions.

Primary Uses

How Does Dicyclomine Work?
