Insulin Pens: Types, Benefits & How to Use Them
Insulin pens are growing in popularity as an alternative to the traditional syringe and vial for injections because they are more convenient and easier to use. Insulin pens may be disposable or reusable, and they include an insulin dose cartridge, a dosage indicator and a disposable needle. Once it is time for an insulin injection, the needle is attached to the tip, and insulin is injected subcutaneously into fatty tissue.
