DRUG CLASS AND MECHANISM: Atropine belongs to a class of medications known as anticholinergics or antimuscarinics. Atropine occurs naturally and is extracted from the belladonna alkaloid plant. Atropine works by blocking the actions of a chemical called acetylcholine. Atropine has numerous uses in clinical medicine and is available in several dosage forms including oral tablet, solution for injection, ophthalmic solution, and ophthalmic ointment. Oral atropine is no longer available in the US.

Atropine produces many effects in the body, including reducing stomach or intestinal spasms, reducing the production of saliva, mucus, and other bodily secretions, and maintaining proper heart rhythm.

PRESCRIBED FOR: Atropine (oral) is used to decrease the production of saliva and phlegm (mucus) in people with an excess of saliva (sialorrhea) and to control stomach or intestinal spasms.


In rare cases, serious allergic reactions including swelling of the lips, tongue or face, difficulty breathing, hives, and closing of the throat has occurred.
