Melanocortin receptor agonists are used to treat low sexual drive in people who haven't gone through menopause, obesity due to specific genetic conditions, and sun sensitivity from a certain condition. These medications work by activating melanocortin receptors in your body, which can influence sexual desire, appetite, and skin pigmentation. Melanocortin receptor agonists come in different forms, including injectables and implants. Examples include bremelanotide (Vyleesi), setmelanotide (Imcivree), and afamelanotide (Scenesse). You can discuss with your prescriber to find the medication that best fits your needs.
