Bentyl (Dicyclomine)

Bentyl is used for treating symptoms of irritable bowel syndrome. It may also be used for other conditions as determined by your doctor.

Use Bentyl as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Bentyl is usually given as an injection at your doctors office, hospital, or clinic. If you will be using Bentyl at home, a health care provider will teach you how to use it. Be sure you understand how to use Bentyl . Follow the procedures you are taught when you use a dose. Contact your health care provider if you have any questions.
• Bentyl is for intramuscular (IM) injection only. It is NOT for intravenous (IV) use.

Bentyl is an anticholinergic. It works by blocking a chemical in the smooth muscle of the stomach and intestines, causing them to relax, which reduces cramping.

If you miss a dose of Bentyl , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Store Bentyl at room temperature between 68 and 77 degrees F (20 and 25 degrees C) in a tightly closed container. Brief periods at temperatures of 59 to 86 degrees F (15 to 30 degrees C) are permitted. Store away from heat, moisture, and light. Do not store in the bathroom.
