Schizophrenia

Hi , I am a doctor by profession. One of my patient was suffering from Schizophrenia . I told him to buy Zyprexa but after some days he came back to me saying that he always experiences dizziness and has the tendency to faint when he stands up .what shall I do ? If I decrease the dose the medicine will not be effective to him .
I want help from my counterpart.

I’m not a doctor, but found the package labeling for Zyprexa. You should be able to find what you need here. Warnings start on page 8. On page 10, this suggests a dosage adjustment in patients who have orthostatic hypotension.
