A severe allergic reaction needs emergency care
An allergic reaction that is severe is a medical emergency.
It can start quickly. Signs can include trouble breathing or swallowing, a swollen tongue or face, or passing out.
Get emergency help if severe symptoms of an allergic reaction develop.
Call 911 or go straight to the nearest emergency room.
This is a reason to get help, not a checklist for ruling a reaction out.

Know the medicine-specific plan
Storage is different for different peptide medicines. Some need refrigeration; others are stored at room temperature.
For storage requirements, follow the instructions on the product’s label and those from the pharmacy.
GLP-1 medicines act like the body’s own signals that help control hunger and blood sugar.
As of September 17, 2026, the Food and Drug Administration (FDA) advises people not to use a GLP-1 injection delivered warm or with too little refrigeration.
Ask the pharmacy about a delivery or label problem before proceeding.
