What is Trilafon (perphenazine)?

Perphenazine is an anti-psychotic medication in a group of drugs called phenothiazines (FEEN-oh-THYE-a-zeens). It works by changing the actions of chemicals in your brain.

These could be early signs of dangerous side effects. Perphenazine is not for use in psychotic conditions related to dementia.
