GLP-1 is not the name of a single drug; it refers to a hormonal pathway involved in appetite and blood sugar regulation. Ozempic is a specific medication brand that belongs to the GLP-1 receptor agonist class. In other words, every Ozempic medication is a GLP-1 drug, but not every GLP-1 drug is Ozempic. Medications such as Wegovy and Mounjaro also affect similar metabolic systems. Online discussions often use the terms interchangeably, but medically they are not identical concepts.
