This page covers practical-use information, such as storage, injection, and disposing of your pens.
Things to know
Lantus is available in vials, pre-filled disposable pens and cartridges for use with a reusable pen. Your diabetes nurse or doctor should talk to you about which of these options is suitable for you and how to use it.
The information in this section will help you keep your insulin in good condition by storing it correctly.
Check the expiry date
Before using Lantus, always check the label to ensure you have the correct insulin and that it has not passed its expiry date. The expiry date can be found on the pen, cartridge or vial and its outer box.
The right needle for you
Your Lantus SoloStar or cartridge device can be used with a range of small, disposable needles of different sizes. The needles are small to minimise any discomfort. Your doctor or nurse will choose the right size needle for you.
Storage
Before it is opened for the first time, Lantus should be stored in the fridge at between 2°C and 8°C and kept in its outer packaging.
Don’t let it freeze and only use it if the solution appears clear with no visible particles.
After opening, your insulin should be kept at a temperature of less than 30°C in its outer carton, out of direct light and away from sources of heat such as a radiator.
Once opened, the vials can only be used for 28 days. So, write the use-by date on the label to help you remember and discard the vial after four weeks.
