Malfunctions might result in improper medication delivery, causing too much or too little dose. Proper handling and storage of the pen are crucial to avoid these issues.

Troubleshooting Wegovy Pen Malfunctions

Wegovy pen malfunctions can frustrate both patients and medical professionals alike. Addressing delivery problems promptly ensures the effectiveness of Wegovy for weight loss before and after treatment periods. Here are the steps to fix these issues:

  • Check the Pen’s Exterior: Inspect the Wegovy pen for visible damage before use.
  • Verify Storage Conditions: Ensure the pen has been stored according to guidelines.
  • Prime the Pen if New: For first use, prime by turning the dose selector until it clicks twice.
  • Ensure Proper Needle Attachment: Attach the needle tightly, but avoid over-tightening.
  • Perform Air Shot Test: Conduct an air shot by selecting a 2 mg dose and pressing the button upward.
  • Select Correct Dose: Adjust the dose selector to match your prescribed dosage.
  • Inject at Recommended Sites: Administer the injection into clean, recommended sites for best absorption.
  • Beware of Blockages: If no medication is dispensed, replace the needle and try again.

Addressing Dosage Inaccuracies

Dosage inaccuracies in the Wegovy pen can lead to concerning outcomes for patients aiming for weight loss. Addressing these errors promptly ensures that the treatment remains effective and safe. Here’s how medical professionals can tackle dosage inaccuracies step by step:

  • Confirm Dose: Verify the prescribed Wegovy dose, as it may differ from other medications like Saxenda or Mounjaro.
  • Check Settings: Ensure the pen’s current dosage settings match the prescribed dose.
  • Instruct Usage: Guide patients to align the dose selector with their prescribed dose.
  • Review Results: Show Wegovy weight loss before-and-after pictures to motivate accurate dosing.
  • Explain Dose Increases: Emphasize gradual dose increases to avoid side effects, as per Wegovy guidelines.
  • Encourage Logging: Suggest patients log doses and side effects for adjustments.
  • Set Reminders: Recommend setting reminders for dose days to avoid missed doses.
  • Assess Technique: If dosing issues persist, evaluate the patient’s technique in person.
  • Seek Assistance: For ongoing problems, contact Novo Nordisk for guidance or pen replacement.

Preventing Wegovy Pen Malfunctions

Storing and handling Wegovy correctly helps prevent malfunctions. It also ensures the medication remains effective for those who need it.

  • Keep Wegovy in the fridge at 36°F to 46°F (2°C to 8°C) before first use.
  • Avoid freezing; it can destroy the medication’s effectiveness.
  • Once you start using a Wegovy pen, you can keep it at room temperature, up to 77°F (25°C), for up to 28 days.
  • Protect the pen from direct light and heat, as these can degrade the medicine.
  • Always check the liquid in the pen; it should be clear and colorless. Don’t use it if it’s cloudy or has particles.
  • Wash your hands thoroughly before handling Wegovy to keep everything clean.
  • Use a new needle with each injection to avoid infections and ensure proper dosage.
  • Don’t shake the pen; this might lead to air bubbles that could cause incorrect dosing.
  • Record each dose date on a calendar—to help recall when and if the dosage was administered.
  • Dispose of used pens and needles safely in a sharps disposal container.

Following these tips helps maintain Wegovy’s integrity, whether comparing Wegovy to Saxenda or Wegovy to Mounjaro or assessing its mechanism, such as how Wegovy works generally.

If your Wegovy pen continues to malfunction despite attempts to fix it, seek professional help. Persistent delivery issues or dosage inaccuracies warrant consulting a healthcare provider. Doctors and pharmacists can offer advice or alternative solutions.
