How Long Does Semaglutide Last in the Fridge?

Sterile medicines carry a beyond-use date and storage instructions for that container. USP standards sit behind those dates. Your vial or pen is not a generic object this article can time for you.

Refrigerate if the label says to, generally in the range people mean by a normal fridge, not in the door if the door swings warm, and not against a freezer wall that freezes the liquid. Freezing is not 'extra cold and therefore fine.'

A cold pack does not survive a summer afternoon on concrete, and a January porch can be its own problem. Have a person take the box inside the day it arrives. Hotel desks and apartment lobbies are where packages wait too long.

If you are unsure whether a dose got too warm or froze, do not guess and inject it. Ask the pharmacy or your clinician with the details. Replacing a dose is cheaper than using a ruined one.

Is 28 days always the rule?

No. Use the date printed on what you were dispensed. Different products and different preparations are not the same clock.

Can I travel with it?

Yes, with a plan that matches the label. Do not check a vial you need this week if the cargo hold is a guess. Ask before a long trip.
