Does Zyprexa heighten or lower serotonin levels? By the way, what would is serotonin anyway?

I sure hope they aren't going to make me retarded. I used to be very spacey as a child and it wasn't until I finally became normal that they put me on Zyprexa.

Zyprexa works to reduce symptoms of schizophrenia by blocking various serotonin and dopamine receptors. It blocks the serotonin (5HT2A) receptor more potently than the dopamine (D2) receptor. In animal studies, Zyprexa is more potent at blocking serotonin and dopamine than Clozaril.

Serotonin (5-hydroxytryptamine, or 5-HT) is a monoamine neurotransmitter synthesized in serotonergic neurons in the central nervous system (CNS) and enterochromaffin cells in the gastrointestinal tract of animals including humans. Serotonin is also found in many mushrooms and plants, including fruits and vegetables.

Hope this info helps you. Here is a page with a lot more info on Zyprexa.
