Insulin Storage Tips

• Insulin in use is stable at room temperature for one  month (check company monograph for temperature range).

• Store insulin away from  direct heat and  sunlight.

• Keep extra cartridges or vials of insulin in the fridge. When  refrigerated, unopened insulin is good  until  the expiry date.


• Always check the expiry dates.

• Do not  use your insulin if:

•  Clear insulin is not  clear.

•  Cloudy  insulin clumps and/or does  not  mix properly.

Store pre-filled syringes in the fridge, with needle tips up. They are stable for 1 month.

Roll end-to-end several times prior to use to re-suspend the insulin.
