Patients taking anti-obesity medications (such as orlistat, phentermine/topiramate, naltrexone-bupropion, liraglutide, and semaglutide) have been shown to lose up to 12% more weight than those following a lifestyle plan alone.

Anti-obesity medications are approved for patients with a body mass index (BMI) ≥ 30 or a BMI ≥ 27 with a comorbidity. Other considerations include patients who are actively engaged in self-care, conscientious of their diet but struggling to make dietary changes, unable to lose or maintain a lower body weight, and who have a desire for improved health.

Most anti-obesity medications are generally intended for long-term use, as discontinuation might result in reemergence of increased appetite and weight regain. Phentermine, diethylpropion, benzphetamine, and phendimetrazine are approved for short-term use.

Anti-obesity medications should be used in conjunction with lifestyle modifications.
