Dicyclomine is a medication used to help treat functional bowel or irritable bowel syndrome by easing muscle spasms in the digestive tract. It works by blocking certain signals in the body that cause these spasms, helping to reduce discomfort. You take it in capsule form, starting with a dose of 20 mg four times a day, which can be increased to a maximum of 40 mg four times a day after a week, unless side effects occur. It's important to know that this medication should not be used by infants under 6 months old or nursing mothers. Additionally, if you have glaucoma, you should avoid using dicyclomine.
