I was injected with invega one time and had no insomnia. I then took it after that about a year later for almost a decade and started developing insomnia while on it.
No guarantees it will completely go away. Im in rexulti now which makes me sleep better.
I was on risperidone which is similar to Invega. I also developed insomnia on it & it hasn’t gotten better since coming off a month ago. I’ve read that sometimes it gets better & sometimes it doesn’t. I feel screwed because I can’t stay asleep. I wake up all throughout the night
