Short pen needles – Reliable subcutaneous injection

To achieve a good insulin dose effect it is essential to inject the insulin into the subcutaneous fatty tissue (subcutaneous injection) and not into the underlying muscle. Injecting insulin into the muscle can lead to unexplained fluctuations in blood glucose values as well as to severe hypoglycaemia.

  • A trend towards shorter pen needles is apparent.
  • 4 mm and 5 mm pen needle simplify the injection technique. Injections can often be given at a 90 degree angle without creating a skin fold (children, adolescents and slim adults should form skin folds).1
  • Short pen needles reduce the risk of inadvertent injections into the muscle which can lead to severe hypoglycaemia.

 Short pen needles permit safe
    subcutaneous injection without forming 
    a skinfold.Follow the recommendations 
    of your diabetes counsellor.

  Long pen needles increase the risk of
      injecting into the muscle.
