Managing diabetes can be challenging, especially when you need insulin. While insulin pens have become a preferred injection method for many diabetics due to their ease of use, it's important to learn how to handle them correctly.

How Do You Know When an Insulin Pen is Empty?
Insulin pens are handy and easy-to-use injection devices for those with either type 1 or type 2 diabetes who require regular insulin injections. Other insulin injection devices include insulin pumps and insulin syringes that must be filled from insulin vials.
Insulin pens include a cartridge prefilled with insulin and a dial to set your dose. They must be used with disposable needles. There are three types of insulin pens:
- Disposable insulin pens, which are disposed of after the insulin cartridge is empty.
- Reusable insulin pens, which allow for the cartridge to be replaced once empty.
- Smart insulin pens, which are advanced injection pens that can track dosage timing and amount and usually work with replaceable cartridges too.
No matter which type of insulin pen you use, recognizing when the cartridge is empty is important. This vigilance helps you keep track of your stocks of insulin and ensure your diabetes management stays uninterrupted.
By staying on top of your insulin pen levels, you can avoid missed doses and prevent fluctuations in your blood sugar levels.

Spotting an Empty Insulin Pen
- Look through the cartridge. Most insulin pens are designed with a see-through window where you can easily observe how much insulin is left and quickly identify when your insulin pen is near empty. Similarly, if you notice the rubber plunger is near the end of the cartridge, it means you have little insulin left.
- Test the dose dial. Attempt to set a dose on the pen. If it stops short or won't turn, your pen cartridge is likely empty. For safety, insulin pens are designed to prevent dialing more insulin units than they can dispense.
- Automatic locking. Some advanced smart insulin pens give a clear indicator or stop functioning when they're empty, aiming to prevent attempts to dose without sufficient insulin. Consult the specific pen's user manual or speak with a healthcare provider to understand the features of your specific insulin pen, as models can vary significantly in functionality and safety features.

How to Dispose of Empty Insulin Pens
Disposing of an empty insulin pen responsibly ensures both safety and environmental sustainability. Whether you're using a disposable or reusable pen, the way you discard it matters.
- Disposable insulin pens: Once your pen is empty, the entire pen must be disposed of according to Canadian regulations on the safe disposal of prescription drugs.
- Reusable insulin pens: These pens allow you to replace the empty insulin cartridge with a new one. The pen itself is kept, reducing waste. However, the insulin cartridges still need proper disposal once they are empty.
Disposing of Your Empty Pens Properly
What to do with your empty insulin pens depends on the type of pen you have:
- Disposable insulin pens, such as the FlexPen, Lantus SoloStar, and KwikPen, can be disposed of in regular household trash once they're empty. However, you must remove the needle first and place it securely in a sharps disposal container to prevent injury or contamination.
- Reusable insulin pens, like the NovoPen and ClickStar are designed for long-term use with replaceable insulin cartridges. These should not be discarded with your regular household waste. Refer to the manufacturer's guidelines for safe disposal.
- Smart insulin pens, such as the Medtronic InPen (USA only), NovoPen4 and NovoPen Echo (available in Canada) contain electronic components that require special disposal considerations. If your pen is broken or stop functioning, reach out to the manufacturer to ask about proper disposal, often through specialized recycling or take-back programs that handle electronic waste safely.
Additionally, always enquire about your local waste management policies. Some areas have specific rules about disposing of medical waste, including insulin pens and cartridges. Ensure you comply with these regulations to contribute to safe and sustainable waste management.
