A 45-year-old obese man is evaluated in a locked psychiatric facility. He was admitted to the unit after he was caught running through traffic naked while tearing out his hair. His urine toxicology screening was negative for illicit substances and after careful evaluation and additional history, provided by his parents, he was diagnosed with schizophrenia and was treated with aripiprazole. His symptoms did not improve after several dosage adjustments and he was placed on haloperidol, but this left him too lethargic and slow and he was placed on loxapine. After several dosage adjustments today, he is still quite confused. He describes giant spiders and robots that torture him in his room. He describes an incessant voice screaming at him to run away.
