What is a recommended practice when using insulin pens?

Using a new needle for each injection is a recommended practice when using insulin pens to ensure both the effectiveness of the medication and to minimize the risk of infection. When a new needle is used, it maintains the sterility of the medication delivery system, reducing the likelihood of introducing bacteria into the skin at the injection site. Additionally, using a fresh needle helps to improve the accuracy of the dosage by providing a clean, sharp point that can deliver the insulin more effectively. This practice also helps to avoid issues such as needle dullness, which can cause pain and discomfort during injection.

Re-using needles can increase the risk of contamination and may lead to needle blockage, which can affect the delivery of insulin. Storing insulin pens only at room temperature does not account for the specific storage recommendations based on the type of insulin, and shaking the pen vigorously is not appropriate as it can lead to the formation of bubbles in the insulin, which can affect dosing accuracy. Overall, using a new needle every time supports safe and effective diabetes management.
