Generic forms of this medication are usually prescribed as pilocarpine ophthalmic. The main purpose of this medication is to reduce the pressure within the eye and to prevent the pupil from achieving full dilation, which allows for less light to enter the eye. It is regularly prescribed for patients who are suffering from glaucoma, and can be used to reduce pressure in the eye before surgical procedures. It is also prescribed for patients who are taking other medications which cause the pupil to dilate too readily, causing painful reactions to bright light.
