Uses

Dicyclomine is used to treat a certain type of intestinal problem called irritable bowel syndrome. It helps to reduce the symptoms of stomach and intestinal cramping. This medication works by slowing the natural movements of the gut and by relaxing the muscles in the stomach and intestines. Dicyclomine belongs to a class of drugs known as anticholinergics/antispasmodics.

This medication must not be used by children younger than 6 months because of the risk of serious side effects.

How to Use This Medication

If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. Mix the dose of liquid with an equal amount of water before taking it.
