How does Prochlorperazine work?

Mechanism of Action

Prochlorperazine works by blocking dopamine receptors in the brain. Dopamine is a chemical messenger that transmits signals between nerve cells. By interfering with these signals, the medication can help stabilize brain activity and reduce specific symptoms.

Control of Nausea and Vomiting

Rectal: Suppositories are used by inserting them into the rectum, which is often necessary if severe nausea or vomiting prevents taking medication by mouth.

Injection: This medication may be given as an injection into a muscle or a vein by a healthcare professional in a clinical setting.

Prochlorperazine can generally be taken with or without food. It is important to follow the specific schedule provided by your healthcare provider to maintain consistent levels of the medication in your body.

There is limited information regarding the safety of prochlorperazine during pregnancy. It is generally recommended only when clearly needed and after a discussion with a healthcare provider about potential risks and benefits.

Tremors or muscle stiffness

Muscle weakness

Sleepiness

Difficulty breathing

Feeding problems

Agitation

If you become pregnant while taking this medication, contact your healthcare provider to discuss your treatment plan.

Breastfeeding

Question 11

What is the FDA approval status of Prochlorperazine?

Accepted Answer

FDA Approval and Indications

Prochlorperazine is approved by the U.S. Food and Drug Administration (FDA) for the management of severe nausea and vomiting of various causes. It is also indicated for the treatment of schizophrenia and for the short-term treatment of generalized non-psychotic anxiety.

Boxed Warning

The FDA requires a boxed warning for prochlorperazine because elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Prochlorperazine is not approved for the treatment of patients with dementia-related psychosis.

Pediatric Regulatory Status

The FDA has established specific age and weight restrictions for the use of prochlorperazine in children. It is contraindicated for use in pediatric patients under 2 years of age or weighing less than 20 pounds. Due to the risk of severe extrapyramidal reactions, its use in children should be limited to conditions where the potential benefits clearly outweigh the risks.

Safety Warnings

Regulatory labeling includes warnings for several serious conditions associated with prochlorperazine use:

Tardive Dyskinesia: A syndrome of potentially irreversible, involuntary movements that may develop in patients treated with antipsychotic drugs.

Neuroleptic Malignant Syndrome (NMS): A potentially fatal symptom complex characterized by hyperpyrexia, muscle rigidity, and autonomic instability.

Falls: Prochlorperazine may cause somnolence, motor instability, and orthostatic hypotension, which can lead to falls and subsequent injuries.

Question 12

What should I know about Prochlorperazine and withdrawal?

Accepted Answer

Withdrawal Symptoms

Stopping prochlorperazine suddenly after long-term use or high doses can cause physical symptoms. These effects are more likely to occur if the body has become accustomed to the medication over time.

Commonly reported withdrawal symptoms include:

Nausea and vomiting

Dizziness

Shakiness or trembling

Stomach inflammation or discomfort (gastritis)

How to Stop Safely

It is important to follow a doctor's instructions when discontinuing prochlorperazine. A healthcare provider will typically create a schedule to slowly decrease the dose. This tapering process helps the body adjust and reduces the risk of unpleasant side effects. In some instances, a doctor may recommend continuing other specific medications for a few weeks after stopping prochlorperazine to help manage the transition.
