Class II U.S. Food and Drug Administration

Novo Nordisk Inc. Wegovy Injection, 1 mg/0.5 mL, 4 Single-Dose Prefilled Pens recall: Presence of Particulate Matter: Hair was found in a prefilled syringe

Recall published 10 months ago

Presence of Particulate Matter: Hair was found in a prefilled syringe

The hazard: Sterility or particulate concern

The concern here is contamination of a product that bypasses the body’s normal defences, which is why the threshold for recalling it is low.

What the notice says: Presence of Particulate Matter: Hair was found in a prefilled syringe

Why it matters: The product was made or packaged in conditions that cannot assure sterility, or visible particles were found in it. For anything injected, infused or used in the eye, that is a direct route for contamination into the body.

Symptoms and when to call a doctor

Watch for fever, chills, pain, redness, swelling or discharge at an injection site, and for a red, painful or suddenly blurred eye after using an eye product. Any of these needs same-day medical attention. Do not wait to see whether it settles, and tell the clinician which product and lot you used so it can be reported against the recall.

This page is general information, not medical advice. If you feel unwell, a clinician who can see you is the only person able to judge your case.

What to do about Sterility

Novo Nordisk Inc. — The concern here is contamination of a product that bypasses the body’s normal defences, which is why the threshold for recalling it is low.

  1. Stop using the affected lot and check the lot number on your own carton or vial against the codes listed above.
  2. Do not use a vial or syringe with visible particles, cloudiness or discolouration, whether or not it is on the recall list.
  3. Call your prescriber or pharmacy today about a replacement from an unaffected lot — do not simply skip doses of a medicine you depend on.
  4. If you are a clinic or pharmacy, quarantine the stock and work it through your usual recall log.

Getting a replacement supply

Do not let a refund question interrupt your treatment. Deal with the supply first and the money second.

  • Call the pharmacy before you run low. They can see which lot they dispensed to you and will usually swap it the same day.
  • Insurers do not normally count a recall replacement against a refill limit. If one is refused, ask the pharmacist to call it through as a recall override.
  • Over-the-counter products are refunded at the till like any other purchase; the recall notice on your phone is enough to explain the return.
  • If the manufacturer runs a direct reimbursement form, it will be linked from the official notice on this page.
