How Does Ozempic 0.5mg Work?

Ozempic mimics GLP-1 (glucagon-like peptide-1), a hormone that:

• Stimulates insulin secretion in response to high blood sugar.

• Suppresses glucagon (a hormone that raises blood sugar).

• Slows gastric emptying, which prolongs satiety and reduces appetite.

• Administered subcutaneously (under the skin) once a week.

• Inject in the abdomen, thigh, or upper arm.

• Can be taken with or without food, on the same day each week.
