Common questions
Does Compounded Semaglutide need to be refrigerated?
Unopened Compounded Semaglutide should be kept in the refrigerator (36–46°F / 2–8°C). Once you start using an injectable pen, it can usually stay at room temperature for a labeled number of days — check your specific product. Rybelsus (oral semaglutide) is the exception: it is stored at room temperature. Never freeze an injectable pen; if it freezes, do not use it.
How long can Compounded Semaglutide stay out of the fridge?
It depends on the product — the room-temperature window printed on your label is the one that applies, and it varies widely by drug. If you're unsure how long it sat out, ask your pharmacist before using it.
