MINIMS ® Phenylephrine is used to enlarge the pupils of the eye(s). This might be so that the doctor or eye specialist can examine your eye(s) closely. MINIMS ® Phenylephrine is sometimes used in open-angle glaucoma to reduce the pressure inside the eye. This is achieved by phenylephrine’s ability to narrow blood vessels which then reduces the production of fluid (thick watery substance filling) in the eye.
