Is it possible for zyprexa or geodon (ziprasidone) or haldol or risperdal to cause dysautonomia?

Who knows. No one has studied the effects of three antipsychotics simultaneously. One possible mechanism would be if you developed diabetes from one of them, then a dysautonomia could ensue. I recommend you see a neurologist who specializes in dysautonomia and discuss with your psychiatrist whether you really need three antipsychotic medications.
