Chlorpromazine
About Chlorpromazine
Chlorpromazine is an oral prescription medication used to treat certain mental and mood disorders, such as schizophrenia and the manic phase of bipolar disorder. It is also prescribed to manage severe behavioural problems in children and to control persistent hiccups, nausea, and vomiting. This medicine works by helping to restore the balance of certain natural chemicals in the brain.
For this medication to work effectively, you must take it consistently and exactly as prescribed by your doctor. You can take `Chlorpromazine` with or without food, though taking it with a meal or a glass of milk can help prevent stomach upset. Making simple daily adjustments, such as drinking plenty of fluids and avoiding extreme heat, can also support your treatment and improve your comfort.
While taking Chlorpromazine, you may experience mild side effects such as drowsiness, dry mouth, or dizziness when standing up. Most of these are temporary, but you should contact your doctor immediately if you notice serious symptoms like severe muscle stiffness, a high fever, or yellowing of your skin or eyes.
Do not take this if you are in a comatose state, have severe central nervous system depression, or have a history of bone marrow problems. Before starting Chlorpromazine, tell your doctor if you have liver damage, kidney disease, heart problems, glaucoma, or a history of seizures.
This medication can interact with other substances; for example, alcohol can severely increase drowsiness, and certain blood pressure medicines may cause your blood pressure to drop too low. If you are pregnant, planning to become pregnant, breastfeeding, or are an older adult, consult your doctor to discuss whether this medication is safe for you.
