What are injection site reactions and how can I minimize them?

Injection site reactions are common with injectable GLP-1 medications and can include redness, swelling, itching, bruising, or mild pain. These reactions typically occur within hours of injection and resolve within a few days. They're usually mild and don't require medical attention unless severe.

To minimize reactions, rotate injection sites systematically—abdomen, thigh, or upper arm—and avoid using the same spot repeatedly. Allow alcohol to fully dry before injecting, and ensure needles are sharp and used only once. Store medication properly and bring it to room temperature before injection, as cold medication can increase discomfort. If you experience severe reactions, large bruises, or signs of infection (increasing redness, warmth, pus), contact your healthcare provider.
