Anti-obesity medications (AOMs) including liraglutide, semaglutide, and tirzepatide demonstrate efficacy and safety for chronic weight management in randomized controlled trials lasting over one year.

If you are prescribed an FDA-approved anti-obesity medication like semaglutide or tirzepatide, expect it to be a long-term treatment. These drugs have been shown to be safe and effective for weight management over periods of 1-5 years in clinical trials. Because obesity is chronic, stopping the medication often leads to weight regain, so plan for ongoing use and address insurance/access issues early.
