My brother was on clozeril for yrs for scezofrenia, he need to stop the med because his wbc was to low. Anyway , his dr put him on serequel, 200mgs in the morning, and 500mgs at night. He has been anxious abit, and I think he should be increased another 100 mgs in the morning. I think the most you can take of the serequel is 800. But, I think he needs it, cause he gets aggitated and nervous too, maybe Haldol too???
