Suxonium Suxamethonium Chloride Chlorpromazine Hydrochloride
ModerateChlorpromazine is on the leaflet's list of medicines that can interact with suxamethonium chloride. Suxamethonium is a muscle relaxant given by injection in hospital, usually before surgery. Chlorpromazine is an antipsychotic, and the leaflet names it alongside promazine, a related medicine. If you take chlorpromazine, tell the anaesthetist or doctor before any operation so they can plan the anaesthetic with this in mind.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
