The controlled field study (see Effectiveness) included a total of 349 healthy male and female cats in the field safety analysis. Robenacoxib injection treated cats represented 7 breeds, 4 months to 7 years old, weighing 5.5-13.2 lbs. The following table shows the number of cats exhibiting each observation.

The most commonly reported adverse reactions in cats treated with robenacoxib injection were infected incision sites, increased incision site bleeding, vomiting, inappetence, and lethargy. Changes in the clinical pathology values were not considered clinically significant.
An additional study was conducted in client-owned cats to evaluate robenacoxib injection at a dose of 2 mg/kg administered once daily for the control of postoperative pain and inflammation associated with an onychectomy (forelimbs only) and OVH or castration. The study was a masked, negative controlled, multi-center field study in which 187 cats were enrolled in a 2:1 ratio into two groups (127 cats treated with robenacoxib injection and 60 cats treated with saline).

The mean WBC count in the robenacoxib group was 13.8 ± 5.64 103/μL (ranging from 4.4- 36.8) and the mean WBC count in the control group was 12.7 ± 5.41 103/μL (with values ranging from 2.9 - 30.1) at the end of the study. There were 6 robenacoxib cases with elevated ALT post-treatment compared to 1 control case. There were 4 robenacoxib cases with elevated AST post-treatment compared to 1 control case.
The most commonly reported adverse reactions in cats treated with robenacoxib were increased incision site bleeding, leukocytosis, fever, inappetence, infected incision sites, vomiting, and lethargy.
The results of the field study demonstrate that robenacoxib injection, when administered for a maximum of 3 days, is well-tolerated for the control of postoperative pain associated with onychectomy, ovariohysterectomy, and castration in cats.

In a controlled field study (See

), a total of 317 male and female dogs representing various breeds were included in the field safety analysis. ONSIOR-treated dogs ranged in age from 6 months to 15 years and weighed between 2.5 and 53.8 kg. The following table shows the number of dogs exhibiting each observation.

Pain on injection, diarrhea and vomiting were the most commonly reported adverse reactions.
Occurrences of hepatopathy, ataxia, skin lesions/urticaria, and anaphylaxis have been associated with the use of ONSIOR. In a month-long pilot study, 3 dogs that received ONSIOR developed hepatic toxicity. Two of these dogs were euthanized and a third dog recovered after prolonged hospitalization and supportive therapy. In foreign market experience, elevated liver enzymes, hepatic necrosis and death have been associated with the long term use of robenacoxib in dogs. Occurrences of liver failure, hepatitis, and cholangiohepatitis have been reported. In two other field studies, bradycardia, 2nd degree heart block in four dogs, and ventricular arrhythmia in one dog were noted in anesthetized dogs treated with ONSIOR injection.
Injection site reactions (edema, necrosis, and abscesses), and anaphylactic reactions (panting, drooling, shock, pallor, dyspnea, tachypnea, ataxia) have been associated with the use of ONSIOR injection.
