Caring for your insulin pen

Insulin pens, whether they are disposable or reusable, need to be used and stored properly to function safely and effectively. Learn how to care for your insulin pen. As well as the general advice below you should also refer to the manufacturers instructions for specific advice on your pen.

Tips on how to care for your disposable pen

Storing your disposable insulin pen

  • Unopened, you can store your disposable pen at room temperature (not above 30°C) for a maximum of 4 weeks or in a fridge (2°C to 8°C) until the expiry date, but keep it away from the freezing element
  • Once open, your disposable pen will last for a maximum of 4 weeks, whether at room temperature (not above 30°C) or in a fridge (2°C to 8°C)
    • Don’t leave the pen in a car or any other place where it could get too hot or too cold
  • Always keep the cap on the pen to protect the medicine inside from light (opened or unopened)
  • Read our instructions for travelling

Handling your disposable insulin pen

  • Treat your disposable pen with care. Rough handling or misuse could cause inaccurate dosing
  • Don’t drop your disposable pen against hard surfaces. If you drop it or suspect a problem, carefully inspect for damage, attach a new needle and check the insulin flow before you inject
  • Don’t try to refill your disposable pen. Once empty, throw the used pen in a bin or follow your local waste instructions (your package insert will have more information)
  • If your disposable pen is faulty, please don’t try to repair it or pull it apart. Throw it in a bin or follow your local waste instructions and open a new pen

Cleaning your disposable insulin pen
