Side effects of pilocarpine (Isopto Carpine) may include which of the following?

Pilocarpine is a medication primarily used in the treatment of glaucoma and to increase salivation in patients with dry mouth. One of its effects is that it can cause miosis, or constriction of the pupils, which can lead to difficulties with vision, especially in low-light conditions. When pupils are constricted, less light enters the eye, making it challenging for individuals to see well in dim light. This is particularly notable because it directly affects how light is processed in environments with reduced visibility.

The other listed options might appear relevant in different contexts but don't align with the typical side effects associated with pilocarpine. For example, while increased tear production is a therapeutic goal for some uses of the drug, it is not typically classified as a side effect. Itching and blindness also do not directly relate to the expected actions of pilocarpine and are not common side effects encountered by users of this medication. Hence, impaired vision in dim light is the most accurate representation of a side effect associated with pilocarpine use.
