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.
- Short pen needles reduce the risk of inadvertent injections into the muscle.
- 4 mm and 5 mm pen needles simplify the injection technique. Injections can often be given at a 90 degree without forming a skin fold (children, adolescents and slim adults should form skin folds).1

4 mm and 5 mm pen needles often permit safe subcutaneous injections even without forming a skin fold. Follow the recommendations of your diabetes counsellor.

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