How Does It Work?

Dicyclomine is part of a group of medications known as antimuscarinics or anticholinergics. It works by blocking specific receptors (called muscarinic receptors) in the smooth muscles of the digestive tract, helping to relieve the painful spasms associated with IBS. For this reason, dicyclomine is also known as an antispasmodic medication.

When and How to Take Dicyclomine

Some general considerations for those taking dicyclomine include the following:
  • The medication comes in capsule, tablet, syrup, and injectable forms. It is usually taken by mouth four times a day. The injectable form is given as an injection into a muscle and is used in people who temporarily cannot take medications by mouth.
  • You can take dicyclomine with or without food. If you mainly have symptoms after meals, you may want to take it an hour or so before each meal.
  • For the medication to work properly, it must be taken as prescribed. Dicyclomine will not work if you stop taking it.

Dosing Information

The dose of dicyclomine your healthcare provider recommends will vary, depending on a number of factors, including:
  • How you respond to the medication
  • Other medications you may be taking
  • Your age
  • Other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
