Brinzolamide Eye Drop

What is this medication for?

Brinzolamide belongs to a class of medications called carbonic anhydrase inhibitors, which is used to treat glaucoma. Glaucoma is a condition where the nerve in the eye is damaged, and is usually associated with increased eye pressure. Untreated glaucoma can affect your eyesight and cause blindness. Brinzolamide helps to lower the pressure in your eye by reducing production of fluid in the eye.

Brinzolamide may also be used for other indications as prescribed by your doctor.
