It is not clear from your post what the effects and side effects of Invega and Rexulti were and why you made the switches you made. You also write about your psychiatrist's consent to changing escitalopram dosage but again without explaining what prompted the dose change. Lastly, I am unclear what your question is.

I wrote to you in the past that the safety of olanzapine above 20 mg has not been established, but since you have been on more than that for a long time, you are probably OK.
