Hi sir Thanks for seeking help here . Loxapine (several trade names worldwide) is a typical antipsychotic medication used primarily in the treatment of schizophrenia. Olanzepine and clozapine all are anti psychotic. She is taking treatment for psychosis perhaps. But we need symptom clarification for a diagnosis. After adding clozapine if has some effects ....we should observe closely. Remember Clozapine monitoring needed always . The akathesia or restlessness is not the common side effects of Clozapine. So I suggest plaza wait and add a clonotril if sure then propranolol 20 for her. We will observe these symptoms for few more days then will take a decision.
