Company Announcement

March 7, 2019, Norbrook Laboratories Limited of Newry, Northern Ireland is recalling two lots of Enroflox® 100 Injection (enrofloxacin), two lots of Noromectin® Injection (ivermectin) and two lots of Ivermax® 1% Injection (ivermectin) to the veterinarian/consumer level as a precautionary measure as product sterility cannot be assured. There is a concern that if the sterility of these products has been compromised, use of these products could result in introduction of infectious agents to the animal. This may result in the need for medical intervention(s) including, but not limited to the need for supportive care, antibiotics, and/or antifungal drugs.

Norbrook Laboratories Limited discovered that product tested, released and distributed within the USA was manufactured on an aseptic line that subsequently did not pass process simulation tests. To date, Norbrook Laboratories Limited has not received any reports of adverse events related to this recall.

Enroflox® 100 Injection is an antimicrobial used for the treatment and control of bovine respiratory disease and for the treatment and control of swine respiratory disease.

Noromectin® Injection is a parasiticide used for the treatment and control of internal and external parasites in cattle and swine.

The products subject to recall are listed below. The product can be identified by checking the product name, manufacturer details and lot number on the carton or vial.
