Lantus SoloSTAR

Lantus® (
 insulin glargine) is a type of long-acting insulin that is used to treat type 1 and type 2 diabetes. It comes in different forms, including vials and the disposable SoloSTAR® pen device.
 
Lantus was once available in cartridges meant for use in the reusable Opticlik® pen. However, the manufacturer has discontinued this product. 
 
The Lantus SoloSTAR pen is disposable. Each SoloSTAR pen contains 300 units of insulin and is good for 28 days once it is in use, which means you throw it away after it is empty or after 28 days of use, whichever comes first.
