Fits Lilly 3.0 ml insulin cartridges
Measures in 1 unit increments up to 21 units.
Autopen is different to other insulin pens because the insulin is delivered automatically by sliding a side mounted button instead of having to manually press a plunger.
This means that whatever the dose size or needle gauge, it takes the same amount of minimal force every time to inject, without causing any unnecessary pressure or bruising at the injection site. In fact it requires up to 16 times less effort* to inject the same volume of insulin than using a conventional pen with a plunger, making control easier and injections more comfortable. Autopen is compatible with most leading brands of pen needle including Unifine Pentips.
