Treatment Approach for Bulimia Nervosa

• The American Psychiatric Association suggests fluoxetine at 60 mg/day as the recommended pharmacological treatment, administered in the morning, as this dose was statistically significantly superior to placebo in reducing the frequency of binge-eating and vomiting 1, 2, 3, 4

Treatment Algorithm

• A comprehensive evaluation including weighing the patient and quantifying eating and weight control behaviors is essential for initial assessment, according to the American Psychiatric Association 1, 2
• The American Psychiatric Association recommends identifying co-occurring psychiatric disorders, which are common in bulimia nervosa 2
• A physical examination including vital signs, height, weight, BMI, and signs of purging behaviors is necessary, as suggested by the American Psychiatric Association 3
• Laboratory assessment including complete blood count, comprehensive metabolic panel, electrolytes, liver enzymes, and renal function tests is recommended by the American Psychiatric Association 4
• An electrocardiogram is suggested for patients with severe purging behavior, according to the American Psychiatric Association 3
