Pharmacological effect

Antipsychotic drug (neuroleptic), piperazine derivative of phenothiazine.

Special instructions

Perphenazine should be used with caution in case of hypersensitivity to other phenothiazine drugs.

Phenothiazines are used with extreme caution in patients with pathological changes in the blood picture, liver dysfunction, alcohol intoxication, Reye’s syndrome, as well as breast cancer, cardiovascular diseases, predisposition to the development of glaucoma, Parkinson’s disease, gastric and duodenal ulcers, urinary retention, chronic respiratory diseases (especially in children), epileptic seizures, vomiting; in elderly patients (increased risk of excessive sedation and hypotensive effects), in depleted and weakened patients.

The development of tardive dyskinesia during the use of perphenazine is more likely in elderly patients, women and those with brain damage. Parkinsonian extrapyramidal reactions are more often observed in elderly patients, dystonic extrapyramidal reactions – in younger people. Symptoms of these disorders may occur in the first few days of treatment or after long-term therapy and may recur even after a single dose.

In case of hyperthermia, which is one of the elements of NMS, perphenazine should be discontinued immediately.

The simultaneous use of phenothiazines with absorbent antidiarrheals should be avoided.

During the treatment period, avoid drinking alcohol.

Recommendations for the use of perphenazine in children under 12 years of age have not been established. Children, especially those with acute illness, are more likely to develop extrapyramidal symptoms when using phenothiazines.

When used simultaneously with anticonvulsants, the threshold for convulsive readiness may be lowered; with drugs for the treatment of hyperthyroidism, the risk of developing agranulocytosis increases.

When used simultaneously with drugs that cause extrapyramidal reactions, an increase in the frequency and severity of extrapyramidal disorders is possible.

When used simultaneously with drugs that cause arterial hypotension, severe orthostatic hypotension is possible.

When used simultaneously with drugs that have anticholinergic effects, their anticholinergic effects may be enhanced, while the antipsychotic effect of the antipsychotic may decrease.

When used simultaneously with tricyclic antidepressants, maprotiline, and MAO inhibitors, the risk of developing NMS increases.

With the simultaneous use of antacids, antiparkinsonian drugs, lithium salts, the absorption of phenothiazines is impaired.
