According to the UK product information on emc, chlorpromazine is used for schizophrenia and other psychoses, mania and hypomania, and for the short-term management of severe anxiety, agitation and dangerously impulsive behaviour. It controls symptoms; it does not remove their cause. Approved uses and legal status differ between countries, so this page sets them out for the UK, Australia, the USA, the UAE and Russia.
Schizophrenia, psychosis and mania: the UK product information lists schizophrenia and other psychoses, especially where paranoia is a main symptom, as well as mania and hypomania.
Anxiety, agitation and impulsive behaviour: chlorpromazine may be used as a short-term add-on treatment for severe anxiety, agitation, excitement and dangerously impulsive behaviour.
Other UK-listed uses: persistent hiccups, nausea and vomiting in terminal illness when other medicines have failed, lowering body temperature, and childhood schizophrenia and autism.
In Australia, Healthdirect lists Largactil for acute psychosis, long-term schizophrenia, short-term agitation, severe behavioural disturbance in some children, symptom control in terminal illness and intractable hiccups. It relieves symptoms rather than removing their cause. Check your pack label.
Chlorpromazine is a phenothiazine neuroleptic. It depresses activity in the central nervous system and blocks dopamine receptors in the brain, which helps calm psychotic symptoms. It also has anti-sickness, sedative and blood-pressure-lowering effects, which is why drowsiness, dry mouth and dizziness can occur. The liver processes it and it leaves the body in urine and bile.
The UK leaflet says to take chlorpromazine exactly as your doctor or pharmacist has told you. It states a recommended adult dose of 40 mg to 300 mg a day in divided doses, with one third to one half of that for elderly or weak patients. Do not stop or change the dose unless your prescriber says so. Follow the leaflet in your pack or your prescriber’s or pharmacist’s advice.
Age restrictions vary by country. The UK leaflet says children under 1 year should not take this medicine, with a daily maximum of 40 mg for ages 1 to 5 and 75 mg for ages 6 to 12. The Australian consumer leaflet gives no children’s age guidance, and the US label generally advises against use under 6 months unless it may be lifesaving.
Serious reactions can include high temperature with stiff muscles and confusion, yellowing of the skin or eyes, frequent infections, easy bruising, blood clots, a long-lasting painful erection, severe allergic reactions and a serious rash. Seek urgent medical attention for these, for difficulty breathing or for a very fast or uneven heartbeat.
The UK product information says do not store above 25°C. Keep the tablets in a dry place, protected from light, with the container tightly closed. Other countries differ: Australia says below 30°C and the US label says 20°C to 25°C. Keep out of the reach of children and do not use after the expiry date.
