Identifying a Malfunctioning Wegovy Pen
When performing your weekly injection, the Wegovy pen is designed to provide clear visual and auditory cues. Any deviation from the expected process indicates a potential malfunction. It's important to stop immediately if you suspect an issue and not attempt to force the device.
Common signs of injection failure
- No audible clicks: During a normal injection, you should hear two distinct clicks. The first signals the start of the injection, and the second indicates it's still in progress, before the yellow bar stops moving. If you hear nothing or only one click, the dose may be incomplete.
- Yellow bar irregularity: The yellow bar in the pen's window should move consistently during the injection, which takes approximately 10 seconds. If it fails to appear, stops early, or doesn't fill the window, the delivery is likely compromised.
- Liquid leaks: Noticeable liquid leaking from the pen or around the injection site, inconsistent with a small drop, suggests an incomplete dose delivery.
- Difficulty activating: If the button feels jammed or won't depress despite proper placement and pressure, the internal mechanism has likely failed.
Visual inspection checklist
Beyond the injection process itself, a pre-use inspection can reveal potential issues. A malfunctioning Wegovy pen is not always obvious, so a quick check is recommended:
- Inspect the medication: Look through the pen's window. The liquid should be clear and colorless. If it appears cloudy, contains particles, or has changed color, do not use it.
- Examine the pen's exterior: Check for any cracks, damage, or signs of tampering. A compromised device is unsafe to use.
- Check the expiration date: Always confirm the pen has not expired.
Your Immediate Action Plan
If you discover a malfunction, a measured response is key to ensuring your safety and getting a replacement efficiently. Do not panic or try to solve the problem yourself.
- Stop and set the pen aside: Remove the pen from your skin and put it down immediately. Do not attempt to re-inject, press the button again, or repair the device. Wegovy pens are single-use and should never be reused after a failure.
- Record the details: Note the dose strength, lot number, and what you observed (e.g., "yellow bar didn't move," "visible leak"). This information is crucial when contacting the manufacturer and pharmacy.
- Use a new pen, if directed: Unless your healthcare provider or the manufacturer's support team advises you to use a new pen, do not do so. You risk a double-dose if any medication was partially delivered.
Who to Contact for Support
When a pen malfunctions, you have several options for seeking assistance, with the manufacturer being the recommended first point of contact.
- Manufacturer support (Novo Nordisk): Call the Wegovy Navigation Line (1-833-4-WEGOVY) to report the issue. They can troubleshoot, document the problem, and authorize a replacement.
- Your pharmacy: The pharmacy that dispensed your prescription can also help coordinate with the manufacturer for a replacement pen from an unaffected lot.
- Your healthcare provider: Your clinician can offer guidance on managing a missed dose and provide a backup prescription if necessary.
- FDA MedWatch: For significant device malfunctions, you can submit a voluntary report to the FDA, which helps monitor product safety.
Navigating a Missed Dose
If a pen malfunction causes a missed dose, follow the manufacturer's guidelines to avoid dosing errors.
- The 48-hour rule: If your next scheduled dose is more than 48 hours away, take the missed dose as soon as possible with a working pen. If it's less than 48 hours away, skip the dose and take your next one on your regular day.
- Missing multiple doses: If you miss two or more weeks, contact your healthcare provider to discuss how to restart your treatment.
Comparison of Novo Nordisk Injectors
While similar, Wegovy and other Novo Nordisk pens have different protocols. Understanding these differences can be helpful.
| Feature | Wegovy Pen (Single-Use) | Ozempic Pen (Multi-Use) |
|---|---|---|
| Malfunction Action | Set aside safely; do not reuse. | Set aside safely; do not reuse. Check user manual for troubleshooting. |
| Double-Dosing Risk | High if user attempts a second injection without confirmation. | High if user attempts a second injection. Don't dose again without clinical advice. |
| Storage (Room Temp) | Up to 28 days (46-86°F). | Up to 56 days (59-86°F) after first use. |
| Disposal | Single-use; dispose in sharps container. | Dispose when empty (after 4 doses). |
Proper Disposal of a Faulty Pen
Even a malfunctioning pen is considered a sharp and must be disposed of correctly. Never throw it in the household trash.
- Use an FDA-cleared sharps container: Place the pen directly into a designated sharps container.
- Household alternative: A heavy-duty plastic container with a tight-fitting, puncture-proof lid, clearly labeled as hazardous waste, can be used as a temporary solution.
- Follow local regulations: Check with your local waste management for specific disposal guidelines.
Conclusion
Encountering a malfunctioning Wegovy pen can be disconcerting, but a structured and calm approach protects your safety and ensures you can continue treatment effectively. By immediately stopping, documenting the issue, and contacting the appropriate support channels, you can secure a replacement and manage any missed doses correctly. For detailed support and replacement procedures, always contact Novo Nordisk or your pharmacy directly.

How to Prevent Future Malfunctions
While some malfunctions are due to manufacturing defects, many can be avoided by following best practices:
- Store pens correctly: Keep unopened pens refrigerated, but unopened pens can be kept at room temperature (46°F to 86°F) for up to 28 days. Always protect them from freezing or excessive heat.
- Check the pen before each use: Visually inspect the liquid and the pen for any signs of damage or discoloration before each injection.
- Master the injection technique: Ensure you press the pen firmly against the skin and hold it in place until the injection is complete (about 10 seconds), and the yellow bar has stopped moving. Removing it too early is a common cause of incomplete doses.
