Why should you count to at least 3 before withdrawing the needle from the skin after an insulin injection?

Counting to at least 3 before withdrawing the needle after an insulin injection is important primarily because it ensures that all the insulin has been properly injected. Insulin is delivered subcutaneously, and allowing a brief pause helps to ensure that the medication stays within the tissue and does not leak back out of the injection site. This is particularly crucial because an insufficient amount of insulin may lead to inadequate glucose control, affecting the patient’s overall diabetes management.

Additionally, the delay can help in minimizing the risk of insulin being pushed back out through the injection site when the needle is removed. This practice promotes the efficacy of the treatment and helps maintain stable blood glucose levels.
