Uses

Scopolamine (also known as hyoscine) is used to treat cramps (spasms) of the stomach, intestines, kidney, and bladder. It helps to relieve discomfort caused by conditions such as irritable bowel syndrome, gallstones, kidney stones, and overactive/spastic bladder. It works by slowing down the natural movements of the gut and by relaxing the muscles in these parts of the body. This medication is a belladonna alkaloid. It belongs to the class of drugs known as antispasmodics.

How To Use

Take this medication by mouth as directed by your doctor. The dosage is based on your medical condition and response to treatment. Do not increase your dose or take it more often than prescribed without consulting your doctor. Do not take more than 60 milligrams of this medication a day.

Swallow the tablets whole with a glass of water. Drink plenty of fluids while you are taking this medication unless your doctor directs you otherwise.

Antacids and certain anti-diarrhea drugs (adsorbent-type drugs such as kaolin-pectin, attapulgite) lower the absorption of scopolamine. If you also take these medications, take scopolamine at least 1 hour before taking them.

Tell your doctor if your condition lasts or gets worse.
