Insulin is best absorbed in the subcutaneous layer
Insulin injected into the muscle will not be absorbed properly. It may be painful and could be the cause of low or high blood sugars.

Did you know?
Needles come in many lengths from 4mm to 12.7mm long.

New research of the skin shows that on average the skin is only 1.6-2.4mm thick in all people living with diabetes.1, 5

This means that 4, 5 and 6mm needles are suitable for all people living with diabetes who inject.4


Did you know?
How you inject your insulin matters
If you choose to use longer pen needles or syringes, or if you are extremely lean, you may need to perform a skin lift in order to avoid injecting into the muscle.
Review your injection technique with your doctor or diabetes educator today.
