NORBROOK INC: Noromectin Plus Injection for Cattle Recalled for Low Potency

Agency Publication Date: October 1, 2019

Sign in to monitor this recall

Summary

Norbrook Inc. is recalling approximately 11,172 vials of Noromectin Plus Injection for Cattle (ivermectin and clorsulon), a veterinary medication used to treat parasites. The recall was initiated because the product was found to be subpotent, meaning it contains less of the active ingredient than required by the product specifications. This medication was distributed in 50 mL, 250 mL, and 500 mL vials primarily in Iowa, Kentucky, and Missouri. Because the medication is not at full strength, it may not effectively treat the intended conditions in cattle; owners should contact their veterinarian or pharmacist for guidance.

Risk

The affected medication is subpotent, which means it may not contain enough of the active ingredients (ivermectin and clorsulon) to effectively treat or prevent parasite infections in cattle. This could lead to untreated health issues in the animals.

What You Should Do

  1. Check your supply of Noromectin Plus Injection for Cattle to see if your vial size and lot number match the affected products.
  2. Verify the 50 mL vials for lot number 8205-90A and NDC 55529-011-01.
  3. Verify the 250 mL vials for lot number 8205-91A and NDC 55529-011-04.

  5. Contact your veterinarian or pharmacist immediately for guidance on using this product and to discuss alternative treatments for your cattle.
  6. Return any unused vials of the affected lots to the place of purchase for a refund and contact Norbrook Inc. at 913-599-5777 for further instructions.
