psychosis
"I have been on Trilafon (perphenazine) for about 4 years.  I'm on a low does, 4mg x3 times a day.  From what I understand this medicine is a lot more gentle than most medicines that would treat bipolar, schizophrenia, and other forms of psychosis.  Its not good for elderly as the higher the dosage you get the more at risk you are for tardiv dyskinesia (or tremors of the face, arms, and hands).  I am 28 and this medicine worked when Lexapro, Geodon, Haldol, and risperidone wouldn't.  I am given it for Pscyhsis.  In addition I am on 40 mg Viibryd and 0.5mg of Klonopin.  I would recommend this medicine. "
