Uses
INDICATIONS AND USAGE
For control of severe nausea and vomiting.
For the treatment of schizophrenia.
Prochlorperazine is effective for the short-term treatment of generalized non-psychotic anxiety. However, prochlorperazine 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, prochlorperazine should not be administered at doses of more than 20 mg per day or for longer than 12 weeks, because the use of prochlorperazine at higher doses or for longer intervals may cause persistent tardive dyskinesia that may prove irreversible (see WARNINGS).
The effectiveness of prochlorperazine as treatment for non-psychotic anxiety was established in 4 week clinical studies of outpatients with generalized anxiety disorder. This evidence does not predict that prochlorperazine 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.).
Prochlorperazine has not been shown effective in the management of behavioral complications in patients with mental retardation.
History

DOSAGE AND ADMINISTRATION Adults(For children’s dosage and administration, see below.) Dosage should be increased more gradually in debilitated or emaciated patients.
Elderly PatientsIn general, dosages in the lower range are sufficient for most elderly patients. Since they appear to be more susceptible to hypotension and neuromuscular reactions, such patients should be observed closely. Dosage should be tailored to the individual, response carefully monitored and dosage adjusted accordingly. Dosage should be increased more gradually in elderly patients.
1. To Control Severe Nausea and VomitingAdjust dosage to the response of the individual. Begin with the lowest recommended dosage.
Oral Dosage - Tablets
Usually one 5 mg or 10 mg tablet 3 or 4 times daily. Daily dosages above 40 mg should be used only in resistant cases.
2. In Adult Psychiatric DisordersAdjust dosage to the response of the individual and according to the severity of the condition. Begin with the lowest recommended dose. Although response ordinarily is seen within a day or 2, longer treatment is usually required before maximal improvement is seen.
Oral Dosage
Non-Psychotic Anxiety – Usual dosage is 5 mg 3 or 4 times daily. Do not administer in doses of more than 20 mg per day or for longer than 12 weeks.
Psychotic Disorders including Schizophrenia – In relatively mild conditions, as seen in private psychiatric practice or in outpatient clinics, dosage is 5 or 10 mg 3 or 4 times daily.
In moderate to severe conditions, for hospitalized or adequately supervised patients, usual starting dosage is 10 mg 3 or 4 times daily. Increase dosage gradually until symptoms are controlled or side effects become bothersome. When dosage is increased by small increments every 2 or 3 days, side effects either do not occur or are easily controlled. Some patients respond satisfactorily on 50 to 75 mg daily.
In more severe disturbances, optimum dosage is usually 100 to 150 mg daily.
ChildrenDo not use in pediatric surgery.
Children seem more prone to develop extrapyramidal reactions, even on moderate doses. Therefore, use lowest effective dosage. Tell parents not to exceed prescribed dosage, since the possibility of adverse reactions increases as dosage rises.
Occasionally the patient may react to the drug with signs of restlessness and excitement; if this occurs, do not administer additional doses. Take particular precaution in administering the drug to children with acute illnesses or dehydration (see under Dystonia).
1. Severe Nausea and Vomiting in ChildrenProchlorperazine should not be used in pediatric patients under 20 pounds in weight or 2 years of age. It should not be used in conditions for which children’s dosages have not been established. Dosage and frequency of administration should be adjusted according to the severity of the symptoms and the response of the patient. The duration of activity following intramuscular administration may last up to 12 hours. Subsequent doses may be given by the same route if necessary.
Oral Dosage
More than 1 day’s therapy is seldom necessary.
Weight Usual Dosage Not to Exceed under 20 lbs not recommended
20 to 29 lbs 2.5 mg 1 or 2 times a day 7.5 mg per day 30 to 39 lbs 2.5 mg 2 or 3 times a day 10 mg per day 40 to 85 lbs 2.5 mg 3 times a day or 5 mg 2 times a day 15 mg per day 2. In Children With SchizophreniaOral Dosage
For children 2 to 12 years, starting dosage is 2.5 mg 2 or 3 times daily. Do not give more than 10 mg the first day. Then increase dosage according to patient’s response.
FOR AGES 2 to 5, total daily dosage usually does not exceed 20 mg.
FOR AGES 6 to 12, total daily dosage usually does not exceed 25 mg.
