Unused Ozempic pens belong in the refrigerator at 36 to 46 F; the pen in use can live at room temperature below 86 F for up to 56 days.
That 56-day clock applies whether you refrigerate the in-use pen or not, and when it runs out you discard the pen even if doses remain. The hard limits: never freeze Ozempic, and never use a pen that has been frozen; keep it away from heat and light; keep the cap on between doses; and do not store it with a needle attached. Heat is the silent killer for travelers. A pen left in a parked car or pressed directly against an ice pack in a cooler can be ruined without looking any different. Inspect before every injection: the liquid should be clear and colorless. Cloudiness, color, or particles mean the pen is done. If you are ever unsure whether a pen stayed in range, replace it rather than gamble on a degraded dose; your pharmacist can usually help with a replacement question quickly.
What to do
Common questions
Does Ozempic need to be refrigerated?
Yes for unopened pens, and it depends for the pen you are using. Per the label: store new, unused Ozempic pens in the refrigerator at 36 to 46 F (2 to 8 C), where they last until the printed expiration date. Once you start using a pen, you have flexibility: keep it either in the fridge or at room temperature, as long as it stays below 86 F (30 C), and either way you must throw it out after 56 days, even if medication remains. A few hard rules. Never freeze Ozempic, and do not use a pen that has been frozen; freezing destroys the molecule. Keep the pen away from heat and out of direct light, and keep the cap on when you are not using it. Do not store the pen with the needle attached, since that can let air in and medication out. If a pen sat in a hot car or froze in a travel cooler against an ice pack, assume it is compromised and replace it; potency loss is invisible. The liquid should always look clear and colorless. If it is cloudy, colored, or has particles, do not inject it.
