Which of the following is NOT listed as a side effect of parasympathomimetics?

• A. Bradycardia
• B. Ocular irritation
• C. Uveitis
• D. Salivation

Answer: (A)

Parasympathomimetics activate muscarinic receptors, producing rest-and-digest effects such as increased secretions, miosis, and slower heart rate. When used topically in the eye, their action is mainly local and systemic absorption is limited, so bradycardia is not typically listed as a side effect in standard ophthalmic references. Ocular irritation can occur from the drop itself, salivation may occur if any systemic absorption happens, and rare inflammatory reactions like uveitis can be noted in some contexts. Thus, bradycardia is not routinely listed as a side effect for these topical agents.
