I'm on paliperidone injection because I'm non-compliant. I've had literally no side effects from it that I know of, pretty sure my prolactin is fine as I've had blood tests done. Only thing is I can't have it in my arms as it caused the muscle to inflame so I have it in my bum. It's been a rough ride for me on this medication, it took a while to kick in and I've had to keep having it increased as I was getting unwell still while on it. It also seemed to start running out too early in the month. I've been on the highest dose now for about a month or two and I've had some symptoms but I haven't got unwell. We'll see if it holds up.
