Chlorpromazine is an older antipsychotic medicine used for psychosis, severe nausea, and acute manic episodes. It calms agitation, reduces hallucinations, and helps some patients sleep when symptoms are severe. Doctors originally developed it decades ago and it remains in use where newer drugs are not suitable.
Chlorpromazine blocks certain brain receptors that affect mood and perception. That action reduces psychotic symptoms and can control extreme agitation. It also acts on areas that trigger vomiting, so clinicians sometimes prescribe it for severe nausea when other options fail. Dosing varies widely: very low doses for nausea and higher daily doses split across the day for psychosis. Only a clinician should set the dose for your condition.
The most common side effects include drowsiness, dry mouth, constipation, and low blood pressure when you stand up. Movement problems like tremors, stiffness, or restlessness can appear, especially after long use. Weight gain and metabolic changes are possible over months. Rare but serious risks include severe movement disorders, liver problems, and changes in heart rhythm. Older adults with dementia-related psychosis have a higher risk of death on antipsychotics; doctors usually avoid these drugs unless absolutely necessary.
Chlorpromazine can interact with many medicines, including other sedatives, blood pressure drugs, and drugs that affect heart rhythm. Combining it with alcohol or strong sedatives increases drowsiness and breathing risk. Tell your doctor about all prescription drugs, over-the-counter meds, and supplements you use. Pregnant or breastfeeding people should discuss risks and benefits with a clinician before starting treatment.
Take chlorpromazine exactly as your clinician tells you. Don’t stop suddenly without medical advice — withdrawal can cause insomnia, nausea, and recurrence of symptoms. Watch for high fever, muscle stiffness, severe confusion, or fast heart rate; these can be signs of a rare but dangerous condition and need urgent medical attention. Keep regular checkups for blood pressure, weight, liver tests, and movement side effects.
If you consider buying online, use licensed pharmacies that require a valid prescription and show clear contact information. Look for sites with pharmacist access, verified seals, and secure payment methods. Beware of extremely low prices, unknown brands, or sellers that skip prescriptions — counterfeit or expired products are a real risk. When in doubt, ask your doctor where to order safely.

Storage and travel tips. Store tablets at room temperature away from light and moisture. Carry a copy of your prescription when travelling and keep medicines in original packaging. If a dose is missed take it as soon as you remember unless it is almost time for the next dose; don’t double up. If you notice unusual side effects call your prescriber. For questions about brands, generics, or cost savings ask the pharmacist — they can explain options available locally.
