For control of severe nausea and vomiting.For the treatment of schizophrenia.Compazine (prochlorperazine) is effective for the short-term treatment of generalized non-psychotic anxiety. However, Compazine is not the first drug to be used in therapy for most patients with non-psychotic anxiety, because certain risks associated with its use are not shared by common alternative treatments (e.g., benzodiazepines).When used in the treatment of non-psychotic anxiety, Compazine should not be administered at doses of more than 20 mg per day or for longer than 12 weeks, because the use of Compazine at higher doses or for longer intervals may cause persistent tardive dyskinesia that may prove irreversible (see WARNINGS).The effectiveness of Compazine as treatmentfor non-psychotic anxiety was established in 4-week clinical studies of outpatients with generalized anxiety disorder.This evidence does not predict that Compazine will be useful in patients with other non-psychotic conditions in which anxiety, or signs that mimic anxiety, are found (e.g., physical illness, organic mental conditions, agitated depression, character pathologies, etc.).Compazine has not been shown effective in the management of behavioral complications in patients with mental retardation.
Do not use in patients with known hypersensitivity to phenothiazines.Do not use in comatose states or in the presence of large amounts of central nervous system depressants (alcohol, barbiturates, narcotics, etc.).Do not use in pediatric surgery.Do not use in pediatric patients under 2 years of age or under 20 lbs.Do not use in children for conditions for which dosage has not been established.
The extrapyramidal symptoms which can occur secondary to Compazine (prochlorperazine) may be confused with the central nervous system signs of an undiagnosed primary disease responsible for the vomiting, e.g., Reye’s syndrome or other encephalopathy.The use of Compazine (prochlorperazine) and other potential hepatotoxins should be avoided in children and adolescents whose signs and symptoms suggest Reye’s syndrome.
