Perphenazine
"I have been on Trilafon for 2 years now. Mostly I liked it at first because it brought me back to earth when I was over anxious. I have lowered my dosage since then and I thought it was doing me well, but I have been having neck problems lately and have realized that this is a side effect of Trilafon called extra-pyramidal syndrome that damages my posture area, so no matter how hard I try I can't regain a good posture.
