Betagan Overview

Updated: 

Betagan is a prescription medication used to reduce elevated pressure in the eyes of people with chronic open-angle glaucoma or high blood pressure of the eye. Betagan belongs to a group of drugs called beta-blockers. These work by decreasing the amount of fluid produced in the eyes, which reduces overall pressure within the eye.

Betagan comes in the form of an eye drop. It is usually instilled into the affected eye(s) once or twice daily. 

Common side effects include burning or stinging of the eye and inflammation of the eyelids and lining of the eyelids.

Betagan can also cause dizziness. Do not drive or operate heavy machinery until you know how Betagan affects you.

Betagan falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.
