Storing Insulin


  • All insulin needs to be stored below 25 degrees celsius
  • Insulin vials, cartridges or disposable pens should be stored in the fridge
  • at temperature between 2 degrees celsius and 8 degrees Celsius. (It is advisable to take insulin out of the fridge 1 hour before injecting. Cold insulin increases the pain of the injection and slows down the insulin absorption.)
  • Label when first used.
  • Keep syringes, hands and injection areas clean
  • If insulin is exposed to extremes of temperature it is damaged.
  • Freezing insulin destroys it and above 30 degrees Celsius insulin’s activity decreases. Ie in hot cars
  • Check the expiry date throw away if expired.
  • Always follow the instructions


Storing pens


  • The current insulin pen that you are using should not be stored in the fridge. These can be stored at room temperature for up to 28 days.
  • Your spare insulin cartridges and pens should be stored in the fridge until use.
