How long can Kesimpta be out of the fridge?

Kesimpta (ofatumumab) can be kept at room temperature for up to 7 days, as long as the temperature doesn’t get higher than 30 degrees C (86 degrees F). This can be convenient if you are traveling and are not able to keep it in the refrigerator.

Kesimpta should be kept in the refrigerator in the original carton to protect it from light. This applies to both the Sensoready pens and prefilled syringes. You can store Kesimpta in the refrigerator up to the expiration date written on the packaging.

Once you remove Kesimpta from the refrigerator, write the date in the space on the carton. This will help you remember how long the medication has been outside of the refrigerator. If Kesimpta has been stored at room temperature, it must be used within the next 7 days (even if you place it back in the refrigerator), or it must be thrown away after 7 days.

Do not freeze Kesimpta, because this could damage the medication.
