The nurse is preparing educational materials for a patient diagnosed with binge eating disorder. Which FDA approved medication should the nurse anticipate discussing with the patient?

A. Fluoxetine (Prozac): Fluoxetine is a selective serotonin reuptake inhibitor used for depression and bulimia nervosa, but it is not FDA-approved for binge eating disorder. It may be used off-label for comorbid mood symptoms. B. Methylphenidate (Ritalin): Methylphenidate is indicated for attention-deficit/hyperactivity disorder. It is not approved for the treatment of binge eating disorder and does not target compulsive eating behaviors. C. Lisdexamfetamine (Vyvanse): Lisdexamfetamine is FDA-approved for moderate to severe binge eating disorder in adults. It reduces binge frequency by modulating dopamine and norepinephrine pathways that influence impulse control and reward mechanisms. D. Olanzapine (Zyprexa): Olanzapine is an atypical antipsychotic used for schizophrenia or bipolar disorder. It is not approved for binge eating disorder and may cause weight gain, which could worsen binge-related concerns.
