FDA Extends In-Use Shelf Life of Convenia® from 28 to 56 Days

Longer in-use shelf life means improved value for clinics of all sizes

MADISON, New Jersey, January 23, 2012 – The Food and Drug Administration (FDA-CVM) has approved a new product label for Convenia® (cefovecin sodium), the single-injection cephalosporin for treatment of common canine and feline bacterial skin infections. This updated label extends the in-use shelf life of Convenia once the vial has been reconstituted from 28 days to 56 days.

Since its introduction in 2008, veterinarians have trusted Convenia to deliver 100 percent compliance with a single injection.

“Many veterinarians have seen the value Convenia brings to dogs and cats,” said J. Michael McFarland, DVM, DABVP, group director of veterinary operations for the Companion Animal Division with Pfizer Animal Health. “However, some veterinarians—especially those in smaller or feline-focused clinics—have been concerned they may not be able to use the entire vial before the in-use expiration. This new 56-day label for Convenia helps veterinarians provide the best chance for treatment success to their patients because of the guaranteed compliance.”

“Pfizer Animal Health conducted stability studies to extend the in-use shelf life of Convenia in an effort to respond to customers’ requests. This will allow more patients to experience the benefits of Convenia,” McFarland added.

“There has been no change to the formulation or manufacturing of Convenia, so veterinarians can expect the same safety and efficacy they have come to trust from this product.”

The 56-day label applies to all Convenia currently in inventory as well as future inventory of the product.

Veterinarians who have questions about the label update or their current Convenia inventory, should contact Pfizer Animal Health Customer Service at 1-800-733-5500.

CONVENIA is not for use in dogs or cats with a history of allergic reactions to penicillins or cephalosporins. Similar to other cephalosporins, side effects for both dogs and cats include vomiting, diarrhea, decreased appetite/anorexia and lethargy. The safety of CONVENIA has not been determined in lactating or breeding animals.
