Sparhawk Laboratories Inc. has recalled 14,553 cartons of Phenylbutazone 20% Injection (200 mg/mL), a veterinary pain medication for horses. The recall was initiated because the product's pH level was found to be out of specification during a 6-month stability test. This affects 100 mL glass vials sold under several brand names including Sparhawk, Vet One, Henry Schein, Phoenix, Aspen, and Vedco.
A medication with an incorrect pH level can lead to reduced drug stability and may cause irritation or localized tissue damage at the site of injection in animals. No injuries or adverse events have been reported to date.
