Bethanechol is a cholinergic agonist used to stimulate bladder muscle contractions to treat urinary retention.
Bethanechol belongs to a class of medicines called cholinergic agonists. It is designed to mimic the action of a natural chemical in the body that encourages smooth muscle to contract. By doing so, the drug helps organs such as the bladder and the gastrointestinal tract work more effectively. In Hong Kong, Bethanechol is marketed under brand names such as Urecholine.
Both the branded and generic versions are listed on the Hong Kong Pharmacy and Poisons Board’s register of approved medicines. They are supplied by prescription and can be found in community pharmacies and hospital dispensaries across the region.
Bethanechol is primarily used to help the body move urine or food through smooth-muscle pathways. Common conditions include:
These uses are based on the drug’s ability to stimulate muscle contractions in the affected organs. The medication is intended for adult patients, and the specific condition being treated should be confirmed by a qualified health professional.
When taken, Bethanechol activates receptors that belong to the body’s parasympathetic nervous system. This activation encourages smooth-muscle fibres in the bladder wall and the gastrointestinal tract to contract more regularly. The result is a more normal flow of urine or food. Effects are usually felt within a few hours after a dose, but the exact timing can vary between individuals and formulations.
These reactions are generally temporary and resolve without the need for medical intervention.
If any of these signs appear, seek emergency medical help right away.

Store tablets in a cool, dry place away from direct sunlight, and keep the injectable solution protected from freezing. Treatment may be short-term for post-operative issues or longer for chronic bladder conditions; the exact duration should follow the instructions that accompany the prescribed product. Remember that each brand or formulation may have slight differences, so always read the label that comes with your medicine.
Parasympathetic nervous system: The part of the nervous system that promotes rest-and-digest activities, including muscle relaxation and secretions.
Smooth muscle: Involuntary muscle found in walls of organs such as the bladder and intestines, which contracts without conscious control.
Urinary retention: A condition where the bladder does not empty fully, leading to discomfort or a feeling of incomplete voiding.
