If you have diabetes, then you may worry about how to use an insulin pen. But it's simple and safe, as long as you follow the steps below. 

Managing diabetes got a lot more convenient with the invention of insulin pens. Before that, diabetics had to use a syringe and a vial of insulin, fumble around with the tiny pieces, measure out just the right of insulin and then store the vial again -- not exactly travel-friendly for our on-the-go world, is it? 

Thankfully, the process became less painless with the evolution of the insulin pen. They're like portable, easy-to-use gifts to diabetics. Now you can carry everything you need to take care of yourself, right in your pocket or purse (along with everything else in there). They're convenient, accurate and discreet. 

Insulin pens are basically oversized ink pens that come pre-filled with the perfect combination of insulin diabetics need. The cartridge contains up to 300 units of insulin, often a combination of two types – whatever your doctor decides is the best mixture for you.
