Hi Blue_Bird. I'm glad you got some sleep last night and feel better.

I looked it up, and perphenazine has been on the market since 1954. I would hope that if there were any especially concerning dangers that it would be no longer used, 64 years later.

I do understand your anxiety, though. Every new medication brings with it uncertainty. I'd think that if you have any special physical issues that might make taking an antipsychotic like perphenazine risky, that your doctor would have taken that into consideration. I suggest not taking any drug that isn't prescribed with it (like an illegal drug). I'm sure you don't. Definitely update your psychiatrist if you have concerns or side effects. Hugs
