Chlorpromazine
About Chlorpromazine
Chlorpromazine is used in the treatment of schizophrenia or psychosis and bipolar disorder (manic depression). Besides this, it is also used to treat nausea and vomiting, anxiety before surgery, and chronic hiccups (involuntary spasms of the diaphragm). Schizophrenia is characterized by hallucinations symptoms (seeing or hearing things that are not real) and delusions (wrong beliefs). Manic episodes of excitement or depression characterize bipolar disorder. Chlorpromazine prevents the occurrence of these symptoms.
Chlorpromazine contains ‘Chlorpromazine’, which is an antipsychotic drug. It acts by blocking dopamine, a neurotransmitter present in the brain responsible for developing schizophrenia and bipolar disorder symptoms. Chlorpromazine rebalances dopamine to improve thinking, mood and behaviour. It also blocks the other natural substances receptors in the brain, such as histamine and muscarinic receptors, thereby preventing nausea and vomiting.
Take Chlorpromazine as prescribed by your doctor. You are advised to take Chlorpromazine as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, you may experience certain common side effects such as sleepiness, orthostatic hypotension (sudden lowering of blood pressure on standing), dry mouth, abnormality of voluntary movements, weight gain, urinary retention, constipation, muscle stiffness, and tremor. Most of these side effects of Chlorpromazine do not require medical attention and gradually resolve over time. However, if these side effects persist longer, please consult your doctor.
Do not take Chlorpromazine if you are allergic to Chlorpromazine or any other ingredients present in it. Before taking Chlorpromazine, talk to your doctor if you or your family have a history of blood clots, stroke or heart disease or if you are above 65 years and have a history of dementia (memory loss). Chlorpromazine is not recommended during pregnancy as it may affect the unborn baby. Tell your doctor if you are breastfeeding before taking Chlorpromazine. It is not recommended for use in children under 1 year of age. Please do not stop taking Chlorpromazine without your doctor’s advice, as it may lead to withdrawal symptoms.
Uses of Chlorpromazine
Medicinal Benefits
Chlorpromazine works by helping to restore the balance of certain natural substances in the brain. The key action of Chlorpromazine is to block the dopamine receptors (D2) in the brain and correct dopamine's overactivity. Altogether, Chlorpromazine may help decrease hallucinations and help you think more clearly and positively about yourself, feel less agitated and take a more active part in everyday life. On the other hand, it also blocks histamine H1 and muscarinic M1 receptors in the vomiting centre, thereby preventing nausea and vomiting.
