A simple guide to stop your pen from jamming

Important: If you don’t follow these key steps your pen may jam. A jammed pen is not only frustrating but can waste your medication. 

Here’s a guide to keep things working smoothly:

Why might your pen jam?

Common problems:

• Insufficient priming: If you don’t prime, air bubbles can block the flow. It also works like a test so you can check there are no problems with the needle.

• Needle attached incorrectly: If the needle isn't attached correctly, the medication can’t pass through the pen.

Alternatively, some people notice leftover medication in the pen and they think the pen has jammed. It’s normal to have some liquid left after taking all four doses. Make sure you keep a note of each time you take the medication. 

3 key steps to prevent jams

1. Prime your pen before every dose:

   • Why? Priming clears air from the pen so the medicine flows smoothly. This also ensures it works correctly when it comes to your dose. 

   • How? Twist the dose knob until it clicks twice and you see the extended line in the window. Then push the knob down until you see 0. This removes any air bubbles and ensures the pen is ready to deliver a full dose.

2. Ensure the needle is straight and secure:

   • Why? A straight and tight needle ensures the flow isn’t blocked.

   • How? Carefully press the needle into the red inner seal, then screw it on so it’s straight and firmly in place.

3. Pierce the inner seal correctly

   • Why? Proper piercing lets the medication flow freely.

   • How? Steady your hand, pierce the red seal straight, and check that liquid comes out when you prime. If not, try again or use a new needle.

Tips for success

• Read the instructions: Check the patient information leaflet that comes with your pen for additional guidance.
