Class II U.S. Food and Drug Administration

American Regent, Inc. Nitroglycerin injection, USP, 50 mg/10 mL recall: Presence of Particulate Matter: Product contaminated with particulate matter

Recall published 2 months ago

Presence of Particulate Matter: Product contaminated with particulate matter identified as hair, glass and/or paraformaldehyde

The hazard: Sterility or particulate concern

Particulate matter or a sterility failure prompted this notice, the most common reason injectable and ophthalmic products are withdrawn.

What the notice says: Presence of Particulate Matter: Product contaminated with particulate matter identified as hair, glass and/or paraformaldehyde

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.

  3. Do not use a vial or syringe with visible particles, cloudiness or discolouration, whether or not it is on the recall list.

What the company owes you

A recalled medicine is the manufacturer’s cost to carry, not yours or your pharmacist’s.

  • The purchase price or co-pay is refundable, and so is the cost of returning the product if they ask you to ship it.
  • Ask the pharmacy to handle the claim where they can — they process recall returns in bulk and it saves you the correspondence.
  • Keep the carton, the leaflet and the pharmacy label together until the claim is closed.
  • Costs beyond the price of the medicine need to go to the company directly, in writing, with the recall number quoted.
