Manufacture and Distribution of Unapproved Piperazine Products


A supplemental new animal drug application (NADA) filed by Fleming Laboratories, Inc., was approved effective March 23, 1999, for the use of piperazine in chickens, turkeys, and swine for treatment of certain parasitic infections. Notification of this approval was published in the April 29, 1999, Federal Register.

In this same notification, FDA provided that firms without approved NADAs for piperazine for use in food-producing animals could continue to manufacture and distribute piperazine only until August 27, 1999. However, in order to provide for an orderly phase-out, FDA would not object to distribution of this product until December 31, 1999. After that date, unapproved piperazine products may be subject to regulatory action. Firms that currently manufacture and distribute piperazine for use in food producing animals without an approved NADA are urged to submit their NADA to FDA as soon as possible.

Attached is a copy of the April 29, 1999, Federal Register document, which further explains this matter. If you are marketing a piperazine product covered by this notification, please advise Barbara A. Rodgers of your intentions regarding further marketing of piperazine. Responses may be forwarded to Ms. Rodgers' attention at: Food and Drug Administration, Center for Veterinary Medicine, Division of Compliance, HFV-235, 7500 Standish Place, MPN II, Rockville, Maryland 20855.
