The correct answer to this question is – Nausea and vomiting. Bethanechol is a cholinergic agonist drug that stimulates muscarinic receptors. It is mostly used to treat bladder problems such as urinary retention and inability to completely empty the bladder. Bethanechol works by increasing the tone of the detrusor muscle in the bladder.

This causes a contraction in the bladder, and it is sufficient to cause urination and emptying of the bladder. Since bethanechol is a muscarinic receptor stimulator, other effects of muscarinic stimulation will occur. This includes increased gastrointestinal motility, which can cause nausea and vomiting, diarrhea. It can cause an increase in salivation. In high doses, bethanechol can also cause a decrease in cardiac contractions. Therefore, patients taking bethanechol for urine retention may manifest side effects such as nausea and vomiting.

Nausea and Vomiting

Bethanechol will increase GI motility, which may cause nausea, belching, vomiting, intestinal cramps, and diarrhea. Peristalsis is increased rather than decreased. With high doses of bethanechol, cardiovascular responses may include vasodilation, decreased cardiac rate, and decreased force of cardiac contraction, which may cause hypotension. Salivation or sweating may gently increase.
