The next generation in insulin pens comes to Europe first as they use pens 5-8 times more than the U.S. does. The pen can deliver dosages with a minimum dose of 2.0 units and increments of 0.1Units can be made. The Pendiq insulin pen is operated with common 3ml insulin cartridges commercially available in Europe. It has a maximum dose of 60 units. To inject, patients press the ACT button at the base of the pen and a small light flashes red, while the screen displays a countdown. Once the insulin is delivered, the light changes to green and the display reads "end." The pen is rechargeable and the current battery life lasts up to 10 days. It has an alarm that tells when the battery is running low. In case of emergencies, it can be switched to a manual mode. Not yet available in the U.S.
