My dad has a strong immune system and in excellent health otherwise. I think these drugs don’t help. He hallucinates a lot on them. For sundowning there must be a better more relaxing Med that actually help. Cbd made him to sleepy. He has more anxiety on these doctor recommended drugs then before. What’s a solution??
"Quetiapine is a medication that works in the brain to treat schizophrenia. It is also known as a second generation antipsychotic (SGA) or atypical antipsychotic. Quetiapine rebalances dopamine and serotonin to improve thinking, mood, and behavior."
It is also used for BiPolar. Call the doctor that prescribed the med and tell him its not working.
We had a poster here who swore up down and around that the BioMat mini with amethyst crystals (that heats up) calmed his dementia ridden mother down like nothing else on earth. Turned her from an enraged lion into a lamb. The small ones (by Richway) are $700 but there are places that rent them and sell them used, too.

It may be worth a try to rent one, I don't know. At least it's not a drug but a soothing heating pad type of thing that won't hurt him in any way.
Good luck!
