She's on thorazine right now? So here is an advantage of clozapine---lower risk of movements disorders like TD---So if you get TD it might not go away even if you stop taking the AP entirely so its kind of scary but there is a lower risk with clozapine it even seems to mask pre-existing TD in some patients. The typicals like thorazine suck in terms of TD risk and it keeps going up the longer you're on it.
