How it works

From the US prescribing label for the same active substance (Perphenazine). It describes the substance, not this exact product.

ACTIONS Perphenazine has actions at all levels of the central nervous system, particularly the hypothalamus.

However, the site and mechanism of action of therapeutic effect are not known.

Half-life9–12 h

How the body breaks it down

Perphenazine is extensively metabolized in the liver to a number of metabolites by sulfoxidation, hydroxylation, dealkylation, and glucuronidation.

Serious warning

WARNING Increased Mortality in Elderly Patients with Dementia-Related Psychosis Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.

Must not be used by
  • Perphenazine products are also contraindicated in patients with suspected or established subcortical brain damage, with or without hypothalamic damage, since a hyperthermic reaction with temperatures in excess of 104°F may occur in such patients, sometimes not until 14 to 16 hours after drug administration.
  • Total body ice-packing is recommended for such a reaction; antipyretics may also be useful.
