What are some common adverse effects of Bethanechol?

Bethanechol is a cholinergic agent primarily used to treat conditions like urinary retention. As a muscarinic receptor agonist, it encourages parasympathetic activity, which leads to various physiological effects. Common adverse effects associated with Bethanechol include sweating, salivation, flushing, and a decrease in blood pressure.

These effects are due to the activation of cholinergic pathways, which increase glandular secretions (like saliva and sweat) and enhance vasodilation, contributing to flushing and reduced blood pressure. As the drug stimulates smooth muscle contraction, particularly in the bladder, its function promotes urinary voiding but can also lead to the exaggerated cholinergic response, manifesting as sweating and salivation. Understanding these adverse effects helps in anticipating patient responses and managing potential side effects effectively.
