There are a few things to consider when choosing an insulin pen, such as the type of insulin you use, the dose you need, and your personal preferences. You should also speak to your healthcare team to find out which insulin pen is best for you.

If you are having trouble using your insulin pen, speak to your healthcare team for help. They will be able to give you more detailed instructions and troubleshoot any problems you may be having.

When not in use, it is important to store your insulin pen in a cool, dry place. Do not store your insulin pen in the fridge or freezer. Make sure the insulin pen is completely dry before putting the cap back on.

If you are using a reusable insulin pen, you will need to clean it regularly. Cleaning instructions vary depending on the type of insulin pen you have. Speak to your healthcare team for specific instructions. In general, you will need to disassemble the insulin pen and wash all of the parts with soap and water. Rinse all of the parts well and allow them to air dry. Once the insulin pen is completely dry, you can reassemble it and put the cap back on.

It is important to check your insulin pen regularly for signs of damage or wear. If you notice any cracks, bends, or breaks in the insulin pen, do not use it. Dispose of the insulin pen in a sharps container and get a new one from your healthcare team.


Insulin pens are more expensive than syringes and vials, but they are considerably easier to use, less painful, and more readily transportable. The vial and syringe are replaced by a single device, which allows more accurate dosing and simpler administration of doses. Keep insulin refrigerated until you’re ready to use it, and carefully follow the directions on the package. Once opened, keep insulin in a cold, dry place. Insulin, on its own, can help cure diabetes. Maintaining a healthy diet and exercise regimen while taking any prescribed medicines is one of the most effective methods to control blood sugar.
