How do I store my GLP-1 — and travel with it?

Home storage: refrigerator door or shelf, 36–46°F (2–8°C), in the original carton (light protection). Two absolute rules: never freeze — freezing denatures the peptide irreversibly, and a pen that froze is garbage even after thawing — and keep pens away from the freezer vent at the fridge’s back wall, the classic accidental-freeze spot. **, beaches, and direct sun (86°F is the ceiling, and parked cars blow past it in minutes). Flying: - Carry-on, always. Checked-bag holds can freeze — see rule one — and lost luggage means lost therapy. - Medications are exempt from the liquids rule; keeping the pharmacy label/prescription with them smooths security and any medical encounter abroad. - For long-haul or hot-climate trips, an insulated case with a cool (not frozen) pack works; don’t let an ice pack touch the pen directly. - Crossing many time zones? Inject on your usual “day,” roughly any hour of it — weekly drugs are forgiving of a half-day drift. Hot-weather shipping (relevant for telehealth patients): reputable programs ship in insulated packaging with cold packs and track transit. A package that arrives warm is a call-the-pharmacy event, not a shrug — another small test of program quality. The “is it still good?” rule: cloudy, discolored, or particle-containing liquid = discard, regardless of dates. When in doubt with a several-hundred-dollar question, pharmacists answer storage calls all day for free.
