How long can LANTUS® be stored?
Each LANTUS® SoloSTAR® pen contains 300 units of insulin and may be used up to 28 days after the first injection. Before being used, the LANTUS® SoloSTAR® pen should be stored in the refrigerator. Do not store it in the freezer, nor should it be used if it has accidentally been frozen. Once opened, pen should not be refrigerated, but kept at room temperature, up to 86°F. Instruct your patients to keep the LANTUS® SoloSTAR® pen away from direct sunlight. Vials must also be discarded 28 days after being opened. Unlike the LANTUS® SoloSTAR® pen, vials should be refrigerated when not in use.
