What Is Ozempic?

Ozempic is a brand name for semaglutide, a medication used to treat type 2 diabetes. It belongs to a class of drugs called glucagon-like peptide-1 (GLP-1) receptor agonists. Ozempic works by mimicking the effects of the natural GLP-1 hormone, which helps regulate blood sugar levels. It stimulates insulin release, reduces the amount of glucose produced by the liver, and slows down digestion, leading to better blood sugar control. Ozempic is typically administered as a once-weekly 0.5 mg, 1 mg, or 2 mg injection and is often prescribed as part of a comprehensive diabetes management plan that includes diet and exercise.
