Pen Needles

An insulin pen is a convenient way to give yourself an insulin shot or injection. It looks like a large fountain pen and comes in two basic types: disposable and reusable. Disposable pens come prefilled with insulin. When a pen is empty or expired, it is discarded. Reusable pens have a replaceable cartridge of insulin. This cartridge is replaced once the insulin is used or expired.

Insulin pen needles and disposable syringes come in various lengths and widths to suit various body types.

Your size will likely dictate the length of the needle you choose, from 12 mm to 4 mm. For example, children would benefit from the shorter 6mm size.
