A 30-lb weight gain over a 6-month period occurred
following discontinuation of modafinil. Reinstitution of modafinil resulted in a 10-lb. weight loss over a 6-week period. Conclusions: Modafinil treatment resulted in a significant weight loss in this patient, possibly due to reducing clozapine-associated fatigue.
