If you have diabetes, your healthcare provider may recommend Lantus® (insulin glargine), a type of long-acting insulin. Lantus is available in two forms, including:
- Lantus vials -- 10 mL, with 100 units of insulin per mL
- Lantus SoloSTAR® -- 3 mL per pen, with 100 units of insulin per mL.
Lantus was once available in cartridges meant for use in the reusable Opticlik® pen. However, the manufacturer has discontinued this product.
The SoloSTAR pen is disposable, which means you throw it away after it is empty or after 28 days of use, whichever comes first. It is not refillable.
