The U.S. Food and Drug Administration approved a new product label for Pfizer Animal Health’s Convenia (cefovecin sodium) that extends the in-use shelf life of the product from 28 days to 56 days once the vial has been reconstituted.

Convenia, which debuted in 2008, is a single-injection cephalosporin for treatment of common canine and feline bacterial skin infections.

Some veterinarians were concerned about being able to use the entire vial of Convenia before the in-use expiration date, Pfizer said. To address the concerns, the Madison, N.J.-based company conducted stability studies to extend the in-use shelf life of the product. The label change did not correspond with a change in formulation or manufacturing process.

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