What should you do if your Mounjaro pen doesn't click or appears to malfunction?
If your Mounjaro pen for weight loss does not click or appears to be faulty, first check the basics: ensure the paper tab has been removed, the needle is attached straight and securely, both needle shields have been fully removed, and the pen has been primed to expel any air bubbles. Hold the pen firmly at a 90-degree angle against clean skin, press the button steadily until you hear the first click, then keep holding for at least 10 seconds until the second click confirms the dose is delivered. If it still fails after trying a new needle and correct technique, do not reuse it-set it aside, contact your provider or Ely Lilly directly.
- Check needle: Ensure a new, compatible needle is firmly twisted on straight and all shields are fully removed.
- Prime the pen: Tap to remove air bubbles and prime as per instructions before injecting.
- Use proper technique: Press straight onto skin at 90 degrees, use steady pressure on the button, hold for 10+ seconds after first click.
- Inspect pen: Confirm clear medication with no particles/cloudiness, no damage, and smooth dose dial movement.
- If unresolved: Stop using, contact your supplier immediately for guidance - avoid forcing or disassembling.
