How to Use an Insulin Pen

The Benefits of an Insulin Pen

The sleek design and compact size of insulin pens allow accurate, simplified, convenient insulin delivery. Several, but not all, insulin types are available. Your doctor will determine the best option for you.

Pens most often come prefilled and are disposable when empty. A few models may require you to load an insulin cartridge. Multiple doses are possible with each pen or cartridge holding 300 units, packaged five per box for a total of 1,500 units. Possible single-dose amounts range from 1/2 unit up to 80 units, depending on the pen. New, unopened insulin should be refrigerated. Once in use, keep at room temperature, below 86 degrees F. Use according to package insert (10-42 days), specific to insulin type.

If required, load insulin cartridge into pen device. Prior to first-time use, seek instruction from a diabetes educator or pharmacist.
