Psychosis
"I had a very bad experience with perphenazine. I ended up with severe joint pain, difficulty breathing, chest pain, weird spinning sensation in my face on the right side of my nostril, on my forehead and on the right side of my temporal area. I had difficulty urinating and horrible insomnia. It has been well over 6 months since taking up to 12 mg for only a few ( about 2--4 days) and I am still having problems. I started on only 4 mg back in Dec 2013 and took the same dosage up to Mar 2014. I stopped because I could barely urinate. Then, I started have weird movement as stated above in my face, but not as bad as the movement when I took 12mg. The, I was told that I needed to start back on this drug for the movement to disappear."
