There are two types of insulin pens available to you: reusable insulin pens and disposable insulin pens. As well as the overall advantages pens offer over syringes and vials, there are specific advantages that each type of pen offers to you:

Features of Disposable Insulin Pens

Although they are a bit more convenient than reusable insulin pens, since you won’t have to load them with cartridges, they cost more than cartridges with the same amount of insulin in the reusable pens.

Storing Insulin Pens

While the insulin pens can be stored in the refrigerator prior to use, the pens should never be put in the refrigerator after you start to use one. They should be stored at room temperature.

If you’ve stored your insulin pen at room temperature for more than 28 days, than it is time to dispose of the pen with any remaining insulin, and replace it with a new insulin pen.

Insulin Pen Needles

Reusable and disposable insulin pens require a pen needle. Pen needles cost less than insulin syringes. For each injection, you screw on a new pen needle, dial in your dose, insert the needle into the skin and press the button to inject insulin.

Select The Right Insulin Pen For You

More critical than if the insulin pen is reusable or disposable is how much insulin you require at any one time, together with how precise you need the dose to be.

Insulin pens can administer doses in increments of half a unit, one, or two units. Maximum delivery of a single injection ranges from 21 to 80 units.

Children, for example, may need a pen that allows dosing in half-unit increments for mealtime insulin. Someone who takes a daily injection of long acting basal will need a pen that can give a larger dose.

 

Before using either reusable or disposable insulin pens, consult your physician to help you make the right choice.
