Choise of needle length: always keep in mind, that the correct needle length is decisive for a successful therapy: the insulin is injected into the subcutaneous fatty tissue – and to achieve a good insulin dose effect it is essential to inject the insulin into the fatty tissue and not the muscle.
Correct injection technique due to the needle length: for 4mm and 5mm needle length usually make sure to inject at an angle of 90 degrees without a skin fold – whereas for children and slim adults it is recommended to form skin folds. Choosing short needles for injection reduce the risk of inadvertent injections into the muscle. For 6mm and 8mm pen needle length make sure to inject at an angle of 90 degrees with a skin fold or 45 degrees without a skin fold. When forming the skin fold, use your thumb and index finger and keep the skin fold loose and relaxed.
