To ensure that the full prescribed dose of insulin is administered.
Dial up prescribed dose of insulin and inject using injection technique guidelines:

– ensure the injection site is not ‘lumpy’

– inject at an angle of 90 degrees into the skin

– hold the needle in the skin for a count of 10 seconds following the delivery of the insulin

To ensure safe delivery of the insulin
Remove needle from pen device To ensure a sharp needle is used on each occasion.

Insulin (with the exception of Degludec) may be stored at room temperature for one month. (Degludec can be stored at room temperature for eight weeks). Less uncomfortable.
