Compro is FDA-approved for the treatment of severe nausea and vomiting, schizophrenia, and generalized anxiety disorder. It is also used off-label for other conditions as determined by a healthcare provider.
Compro (prochlorperazine) works by blocking dopamine D2 receptors in the brain. This action helps reduce nausea and vomiting signals, and also produces antipsychotic effects by decreasing dopamine-mediated neuronal activity.
Compro may cause drowsiness, dizziness, or blurred vision. It can also cause extrapyramidal symptoms (movement disorders) such as tremor, rigidity, or involuntary movements. This medication should be used with caution in elderly patients with dementia-related psychosis. Avoid alcohol and activities requiring mental alertness until you know how the medication affects you. Always follow your healthcare provider's instructions and inform them of any other medications you are taking.
