Is it possible to take Antipsychotics as PRN's? I'm not feeling the best (voices, paranoia, anxiety) and have some chlropromazine there that I don't take regularly. It's just leftovers from when I was on them before. I'm wondering do they work like that or does it take weeks of continuous use to work?

Edit: I asked my psychiatrist but I couldn't get a straight answer. He said you either take something to control your symptoms or nothing at all. In other words, no PRN for YOU!!
