I first took a 156mg injection of Invega Sustenna near the end of 2015 then a week later a second injection. I slept fine. Then they put me on Olanzapine (Zyprexa) 20mg and I slept fine on that too. Stayed on Olanzapine for about seven months I think then quit and had insomnia. I would stay up all night until 6am then sleep until the afternoon. That probably lasted weeks or months. In 2019 I got put back on Invega Sustenna and stayed on that at the max dose until 2022 then switched to Invega Trinza and I’ve been sleeping just fine on the Invega injections.
Welcome to the forum! I hope you’ll enjoy your stay.
5mg of olanzapine is the lowest dosage. I’m on 20mg. Sometimes olanzapine is prescribed for insomnia, but I haven’t noticed that it works for insomnia at all.
When I can’t fall asleep I take melatonin. Sometimes it works, other times it doesn’t.
I’m on 20 mg of olanzapine, just started a month ago, and i am sleeping 11-12 hours a day, but that could be related more to depression than the meds. IDK. 5 mg is a really low dose.
I have bad sleep issues now. I never connected it to invega, but I was on it for 14 years. In the past I switched from invega to zyprexa. I didn’t have sleep issues then. It’s pretty much been since I got on perphenazine. I also think I have sleep apnea so who knows. One thing I would recommend is an anticholinergic like cogentin. I had to have it when I took those newer antipsychotics or I was too restless to sleep.
My doctor also told me it’s not connected to Invega because I could sleep when the dosage was higher. But I got the insomnia when it was lowered! He also told me maybe it’s connected to the lorazapem but that’s also not possible because I started with that after I got it.
I am currently on invega tapering to olanzapine. I have had severe insomnia and my Drs think that invega is causing it. Good luck I hope things get better for you.
Is your insomnia resolved now or do you still have it? How long did you have the insomnia?
I have quit Invega completely now but my dr told me it’s not connected to invega. He also said it takes time for the stuff to get out completely from the brain and body.
