Chlorpromazine

What is Chlorpromazine?

Chlorpromazine is a prescription medication used to treat certain mental health and medical conditions. It belongs to a group of medicines called **first-generation (typical) antipsychotics**, also known as phenothiazines.

It is approved to treat:

•  Schizophrenia and other psychotic disorders
•  Severe behavioral problems in children (under specialist care)
•  Nausea and vomiting
•  Severe hiccups
•  Acute agitation
•  Mania associated with bipolar disorder

Chlorpromazine is available in several formulations, including:

• Oral tablets (various strengths)
• Oral liquid solution
• Injectable solution (given in a hospital or clinical setting)

The specific form and strength depend on the patient’s condition and clinical needs.

What is the Recommended Dosage of Chlorpromazine?

The correct dosage of chlorpromazine varies based on:

•  The condition being treated
•  Age
•  Body weight (especially in children)
•  Liver function
•  Overall medical history

Available dosage forms include:

Tablets in multiple strengths

Chlorpromazine 50mg

Chlorpromazine 100mg

Oral liquid

Intramuscular injection (administered by a healthcare professional)

Dosing must be individualized and determined by a licensed psychiatrist or other qualified medical specialist. The medication may be started at a lower dose and adjusted gradually.

Patients should never change the dose without medical supervision.

How Chlorpromazine Works

Chlorpromazine works by affecting certain chemicals in the brain, especially **dopamine**.

Dopamine plays a role in mood, behavior, and perception. In some mental health conditions, dopamine activity may be too high in certain brain areas. Chlorpromazine helps reduce this overactivity, which can:

•  Decrease hallucinations
•  Reduce delusions
•  Calm severe agitation
•  Stabilize mood

It helps manage symptoms but does not cure underlying psychiatric conditions. Long-term treatment may be required depending on the diagnosis.

Is a Prescription Required to Buy Chlorpromazine Online?

Yes. Chlorpromazine is a prescription-only medication.

It must be prescribed by a licensed medical specialist, typically a:

•  Psychiatrist
•  Neurologist
•  Internal medicine physician
•  Pediatric specialist (for children)

Patients should avoid purchasing chlorpromazine from unverified sources. Counterfeit or improperly stored medications may be unsafe.

Only obtain this medication from licensed and regulated pharmacies. Never use veterinary or non-human formulations.
