If your injection-pen does not seem to work, you can try the tips in this article

Updated over a week ago

If you’re using an injectable medication like Wegovy, Ozempic, or Saxenda, and your pen doesn't seem to be working, it can be frustrating. However, most issues are easy to identify and resolve. In this article, we'll guide you through common problems and provide steps to troubleshoot and solve them.


1. Check the Pen's Expiry Date

Problem: Your pen might be expired.

Solution:

  • Check the expiry date on the pen packaging or the label. If the medication has expired, it will not be effective.

  • Always store your medication as instructed (typically in the fridge for unopened pens) and ensure you’re using it within the recommended time frame.


2. Ensure the Pen is Properly Primed

Problem: The pen has not been properly primed, leading to the medication not being dispensed.

Solution:

  • Priming is a crucial first step before using an injectable pen, especially for the first time. Priming removes air bubbles and ensures the medication is ready for injection.

  • Follow the instructions provided with the pen for proper priming. Typically, you need to dial a small dose and press the button to release a drop of medication.

  • If you see no medication coming out when priming, try it again until you see a drop.


3. Ensure the Needle is Attached Correctly

Problem: The needle may not be attached properly, preventing medication from being injected.

Solution:

  • Double-check that the needle is securely attached to the pen.

  • If the needle is loose or detached, the medication will not be able to flow.

  • Tighten or reattach the needle if necessary and try again.


4. Check the Needle for Blockages

Problem: The needle may be clogged or blocked, preventing the medication from being delivered.

Solution:

  • Inspect the needle for any visible damage or blockage. If the needle is bent or damaged, it may be unable to administer the medication correctly.

  • If the needle is clogged, you can gently tap the pen to dislodge any air bubbles. If the issue persists, replace the needle with a new one.


5. Verify the Dose Setting

Problem: The dose setting may not be correct, resulting in no medication being injected.

Solution:

  • Ensure that you have set the pen to the correct dose before injection. If the dial is set too low or incorrectly, the medication will not be administered.

  • Double-check the dose instructions and confirm that the correct dose is selected on the pen.


6. Ensure the Pen is Functioning Properly

Problem: The pen may be malfunctioning or broken.

Solution:

  • Inspect the pen for any signs of damage. Check for cracks, leaks, or anything that seems unusual.

  • If the pen appears to be damaged or not functioning as it should, contact your healthcare provider or the medication manufacturer for advice on how to proceed. In some cases, you may need a replacement pen.


7. Proper Injection Technique

Problem: Incorrect injection technique could prevent the medication from being delivered effectively.

Solution:

  • Make sure you are using the correct technique. Follow the instructions on how to properly inject the medication into the skin. The pen should be inserted at the right angle and pressure should be applied.

  • If you feel resistance when injecting, check that the needle is properly inserted and that the medication flow is unobstructed.


8. Check for Air Bubbles in the Pen

Problem: Air bubbles in the pen can prevent proper dosing.

Solution:

  • Tap the pen gently to dislodge air bubbles and ensure that the medication is in the chamber.

  • If air bubbles persist, you may need to prime the pen again to remove them.


9. Store the Pen Correctly

Problem: Improper storage can cause the pen to malfunction.

Solution:

  • Store the pen according to the instructions. Most injectable pens need to be stored in the refrigerator before opening and can be kept at room temperature once in use (but only for a limited period).

  • Extreme temperatures, whether too hot or cold, can affect the medication and the pen’s functionality.


Conclusion

If your pen isn’t working, don’t panic! By systematically checking each of the common issues listed above, you can often resolve the problem quickly. Whether it’s a simple priming issue, a blocked needle, or a malfunctioning pen, following the steps outlined should help restore your medication routine.

If after troubleshooting you’re still unable to get the pen to work, reach out to your healthcare provider or the medication manufacturer. They can offer guidance and ensure that you’re able to continue your treatment without interruption.
