Pilocarpine is a drug used for treating most forms of glaucoma. Glaucoma is a condition in which the pressure of the fluid inside the eye increases, and pilocarpine lowers the increased pressure.

Pilocarpine makes the pupils of your eyes smaller and affects how quickly they react to light by enlarging or narrowing. Smaller pupils and their slower reaction allow less light to enter the eyes. This can hinder you from performing tasks such as driving at night. Be careful when performing such tasks. When used for a long time, the initial improvement may diminish.

Right after you use pilocarpine, your vision may be blurred, but it will clear. You might notice this more when viewing things at a distance.
