An insulin pen is a device for giving insulin shots. The insulin
pen looks like a pen.
Inside the pen is a needle and a cartridge filled with insulin. You
can set the dose of insulin with a dial on the outside of the pen. You use the
pen to give the insulin shot. Both disposable and reusable insulin pens are available.
