A 23-year old male presents to the outpatient clinic for his annual physical exam. He endorses periods of bingeing on certain foods, and then feeling guilty and attempting to purge the calories by inducing vomiting, drinking excessive amounts of coffee and taking laxatives. A nurse observes dental deterioration when assessing the patient. The nurse is preparing educational materials for the patient. Which FDA approved medication should the nurse anticipate discussing with the patient?

A. Fluoxetine (Prozac): Fluoxetine is a selective serotonin reuptake inhibitor approved by the FDA for the treatment of binge-eating and purging behaviors associated with bulimia nervosa in adults. It can help reduce the frequency of binge-purge episodes and improve mood and impulse control. B. Clonidine: Clonidine is an alpha-2 adrenergic agonist primarily used for hypertension and ADHD-related symptoms. It is not FDA-approved for treating bulimia nervosa or its behavioral components. C. Lisdexamphetamine (Vyvanse): Lisdexamphetamine is FDA-approved for binge-eating disorder but not for bulimia nervosa. Its primary use is for reducing impulsive binge episodes in binge-eating disorder without purging. D. Olanzapine (Zyprexa): Olanzapine is an atypical antipsychotic used off-label for agitation or severe anorexia nervosa in some cases, but it is not FDA-approved for bulimia nervosa. Its use carries metabolic and sedation risks.
