Insulin pen

Two types of modern, pre-filled insulin syringes.

An insulin pen is used to inject insulin for the treatment of diabetes. Insulin is a hormone produced by the pancreas. It is composed of an insulin cartridge (integrated or bought separately) and a dial to measure the dose, and is used with disposable pen needles to deliver the dose. It was introduced and marketed as Novopen by the Danish company Novo Nordisk in 1985.

Types of pens

A number of companies make insulin pens including Novo Nordisk, Aventis and Eli Lilly. These companies produce pens for most of their insulins, including NovoLog/NovoRapid, Humalog, Levemir and Lantus.

There are two pen systems: durable and prefilled:

Most brands of insulin are now available for use in pens, these include:

Global Patient Uptake

Insulin pens are used by 95% of insulin-treated patients in Europe, Asia, Australia and Scandinavia with excellent results.[1] They are currently underutilized but growing in use in the United States.

Insulin pens offer several significant advantages over insulin syringes: ease of handling, accuracy, and they are more discreet to use and easier to transport.

Advantages

Insulin pens have a number of advantages:

It is important that proper injection sites on the body be used. A healthcare provider helps determine the best injection site for a patient. In general, recommended injection sites include the abdomen, parts of the buttocks, parts of the upper arms and thigh areas.[2]

Disadvantages

Unlike with the traditional syringe, two different insulins cannot be mixed by the user in an insulin pen.[3] On the other hand, some of the newest types of insulin cannot be mixed at all. In addition, using pens and pen needles is usually more expensive than using the traditional vial and syringe method; insurance coverage for insulin pens in the United States may vary widely, however in the UK insulin dependant diabetics are given pens for free as part of the NHS.

Accessories

Technology has not changed much since the launch of the first insulin pen over 25 years ago by Novo Nordisk.[4] A number of independent companies have created accessories to help people using insulin pens better manage their insulin intake.

- Frio UK [5] offers a wallet to help keep insulin pens cool in warm temperatures, the wallets are activated by immersing in cold water and are capable of keeping insulin cool for a number of days before they require reimmersion.
- Timesulin [6] is a 'smart cap' that works with all major insulin pen types to show users how long it has been since their insulin pen injection to help avoid missed or accidental double doses.
- Bee [7] by Vigilant [8] the Diabetes Smart Tracker serves as a cap for most insulin pens and transmits insulin injection data and glucose levels via Bluetooth to smartphones and tablets.
