Official Stability at Room Temperature
Cosentyx (secukinumab) can stay out of the refrigerator for up to 30 days at room temperature, not exceeding 86°F (30°C). During this time, it remains stable if protected from light and not exposed to freezing or excessive heat.[1][2]
What If It's Been Out Longer?
Discard the pen or syringe if Cosentyx has been unrefrigerated for more than 30 days or exposed to temperatures above 86°F (30°C). Do not return it to the fridge after extended room-temperature exposure, as stability cannot be guaranteed.[1][2]
Travel and Short-Term Handling Rules
For trips or daily use, Cosentyx can be kept at room temperature for up to 24 hours per instance, as long as total out-of-fridge time doesn't exceed 30 days from first removal. Always store in its original carton away from direct sunlight and heat sources like car dashboards.[1][3]
Why These Limits Matter
Secukinumab is a biologic that degrades with temperature fluctuations, potentially losing potency and effectiveness against conditions like psoriasis or psoriatic arthritis. Patient reports on forums note injection-site reactions from mishandled doses, though official data emphasizes following storage to maintain full efficacy.[2][4]
