What To Do With Wegovy Malfunctioning Pen?

Wegovy® (semaglutide) is an FDA-approved medication for weight management that may help eligible individuals as part of a comprehensive treatment plan. Proper Wegovy fridge storage can be important for maintaining the medication’s stability and potential effectiveness. This educational article is about what to do with Wegovy malfunctioning pen.

Wegovy is a once-weekly prescription for chronic weight management that comes in a single-use, prefilled pen. With the dose preset and a hidden needle, the device is designed for simplicity—yet even well-designed devices can occasionally fail. A Wegovy pen malfunction can be frustrating and may interrupt your routine, but there are clear steps to identify problems, stay safe, and get a timely Wegovy pen replacement. This guide walks you through the signs of a faulty pen, immediate actions to take, and how to contact the right people to resolve the issue—without derailing your progress.

Signs of a malfunctioning Wegovy pen

Most injections are straightforward: you’ll hear two clicks and see a yellow bar move across the window during the ~10-second injection. If the pen doesn’t behave as expected, pause and reassess. Common red flags include:

• Visible issues: a cracked case, missing cap, cloudy liquid, particles, or an obvious Wegovy pen leak around the needle area or device body. Do not use a pen if the medicine isn’t clear and colorless, if the cap is missing, the pen looks used, is damaged, or the expiration date has passed.

• Irregular dosing cues: the yellow bar doesn’t start or stops early, you don’t hear both clicks, or you can’t complete the 10-second hold even with firm pressure. These can suggest incomplete delivery or a mechanical issue.

• Difficulty activating: the button won’t depress or the device won’t start despite proper placement and pressure. (Do not force the pen.)

Note: Wegovy pens don’t display electronic error messages. Instead, rely on the visual (yellow bar) and audible (two clicks) indicators and the physical condition of the device.

Common Wegovy pen malfunctions

• Wegovy pen leak: Leakage can stem from internal defects or a compromised seal. If you see liquid on the pen or skin in a way that’s inconsistent with a complete injection, treat it as a malfunction and do not reuse that pen.

• Mechanical failures: Jammed buttons, a stuck or non-moving yellow bar, or early stop before 10 seconds despite firm pressure. These may indicate an internal component fault.

• Incorrect dose dispensing: If visual/auditory cues suggest an incomplete delivery (no second click, bar didn’t advance), the dose may be under-delivered. Do not immediately inject a second pen without guidance; contact support first.

What to do if your Wegovy pen malfunctions

1. Stop and assess. If the device doesn’t activate correctly or you notice a Wegovy pen leak, stop using that pen. Check for clarity of solution, expiration date, physical damage, and whether the cap was removed only once just before use.

2. Do not try to fix or reuse the pen. Don’t attempt to take the pen apart, “push” the rest of a dose, or extract medication. Wegovy pens are single-use; a malfunctioning device should be set aside safely.

3. Record what happened. Note the dose strength, lot number, time, and what you observed (e.g., “yellow bar didn’t move,” “heard first click only,” “visible leak”). These details help support and your pharmacy.

4. Dispose safely if instructed. If told to discard, place the pen in an FDA-cleared sharps container or a heavy-duty, puncture-resistant alternative per local rules. Never throw loose pens in household trash.

How to contact the right channels for assistance

You have several options when a Wegovy pen malfunction occurs:

• Manufacturer support (recommended first):

  • Wegovy Navigation Line: 1-833-4-WEGOVY (1-833-493-4689) (Mon–Fri).

  • Patient Customer Care Center (replacement guidance if medicine is cloudy or pen not working): 1-833-934-6891.

  • Novo Nordisk Product Complaints (U.S.): 1-800-727-6500.
    Support teams can troubleshoot, document product quality issues, and may arrange replacements when appropriate.

• Your pharmacy:
  Ask how they handle defective single-use pens. Pharmacies may coordinate with the manufacturer for a Wegovy pen replacement from an unaffected lot, depending on the situation. Policies vary by pharmacy and plan.

• Your insurance plan:
  If a replacement needs coverage, call the member services number on your card. Plans differ on replacements for lost/damaged/defective medications; your insurer can explain options and any documentation needed. (Novo Nordisk also points patients to their prescription insurance provider for coverage questions.)

• FDA MedWatch (optional but helpful):
  You can submit a voluntary report about product quality problems or device malfunctions. This helps improve safety monitoring nationwide. File online (Form 3500B) or request the form by phone.

Explore replacement options for Wegovy pens

If support determines the pen was defective, they may authorize a Wegovy pen malfunction replacement through the manufacturer and/or pharmacy. Keep the pen and packaging until you receive instructions—sometimes you’ll be asked to return it for quality investigation. If you need medication urgently, ask your clinician and pharmacy about an interim solution (such as a replacement from a different lot) while the complaint is processed.

Alternative solutions while waiting for a replacement

• Follow missed-dose rules (to avoid double-dosing):

  • If your next scheduled dose is more than 48 hours away, you may take the missed dose as soon as possible once you have a working pen.

  • If your next scheduled dose is less than 48 hours away, skip the missed dose and take the next one on your regular day.

  • If you’ve missed ≥2 weeks, talk with your clinician about how to restart or adjust.
    These steps can help you stay on track without increasing side-effects.

• Stay consistent with lifestyle habits. Prioritize protein-forward meals, hydration, sleep, and gentle movement to help maintain momentum during any brief gap. (These are general wellness tips and not medical advice.)

Prepare a back-up plan with your clinician in case of Wegovy pen malfunction

• Discuss ahead of time how to handle a failed injection (who to call first, what details to note, and whether your clinician may provide a backup prescription if appropriate).

• Confirm your pharmacy’s process for documenting defects and requesting replacements.

• Keep a checklist in your injection kit: contact numbers, where to find your lot number, a reminder not to force the device, and a one-line summary of missed-dose guidance.

• Review storage and handling so pens are protected in the fridge (or within room-temperature limits if traveling), which may reduce avoidable failures related to heat, cold, or light exposure.

Quick safety and storage reminders

• Storage: Keep pens refrigerated in the original carton; if needed, unopened pens may be kept at room temperature (46°F–86°F) for up to 28 days. Do not use if previously frozen or exposed to temperatures outside the labeled range.

• Before each use: Inspect the window—use only if the solution is clear and colorless; do not use a pen that’s damaged, looks used, or is past its expiration date.

• During injection: Keep the pen pressed firmly until the yellow bar stops moving (about 10 seconds) and you hear the second click; lifting early may lead to an incomplete dose.

• Disposal: Place used or unusable pens in an FDA-cleared sharps container and follow local guidance for drop-off or mail-back programs.

Conclusion

A Wegovy pen malfunction can be stressful, but a calm, step-by-step response may help you avoid dosing errors and get back on track quickly: stop and assess, document what you see, dispose safely if told to, and contact the manufacturer, pharmacy, and insurer as needed. Keep a proactive plan with your clinician, and remember that brief interruptions don’t have to derail your progress.
