Glucagon-like peptide-1 receptor agonists and related incretin therapies in dermatology: Patient selection and shared...

Glucagon-like peptide-1 receptor agonists and related incretin therapies have moved rapidly from second-line diabetes agents to widely prescribed cardiometabolic medications, and dermatologists increasingly encounter patients who are already taking them. Obesity is common among dermatology patients and is particularly prevalent in psoriasis and hidradenitis suppurativa, yet most eligible patients are not receiving glucagon-like peptide-1 receptor agonist therapy, and nearly all prescriptions originate outside dermatology. This positions dermatologists at the intersection of two distinct clinical questions: how to manage the cutaneous consequences of therapy in patients already receiving these agents, and when to raise the possibility of treatment in patients who may benefit. This narrative review examines patient selection, including the metabolic and inflammatory phenotypes most likely to see dermatologic benefit, and the practical demands of therapy that influence whether treatment succeeds. It reviews the dermatology-relevant adverse effects that patients most often notice, including facial volume loss, hair shedding, and gastrointestinal intolerance, along with a monitoring approach suited to the dermatology visit. Throughout, it argues that shared decision-making offers a useful framework for an area where the evidence is still evolving and where treatment can reshape how patients look and feel.
