Dosage and Administration Give orally without food or with a very small quantity of food. The recommended dosage of ONSIOR is 1 mg/kg body weight with a range 1-2 mg/kg. Administer once per day according to the table below. There is no maximal limit to duration of treatment. Use the lowest effective dose for the shortest duration consistent with the individual response. Contraindications As with all non-steroidal anti-inflammatory drugs (NSAIDs), administration of this drug is contraindicated in the following circumstances: • dogs with gastrointestinal ulcers, renal disease, hepatic disorders, hypoproteinemia, dehydration, cardiac disease or coagulation disorders; • a known hypersensitivity to robenacoxib or its excipients; • concurrent use of other NSAIDs or corticosteroids; • do not use in breeding, pregnant or lactating animals because the safety of robenacoxib has not been established. Information For Dog Owners ONSIOR is the product your veterinarian has chosen to treat your dog’s arthritis pain. It belongs to a class of drugs called “Non-steroidal Anti-inflammatory” or NSAIDs. These drugs must be used according to your veterinarian’s directions. Occasionally, NSAIDs can cause side effects. If your dog stops eating, is depressed, vomits or has diarrhea stop the drug immediately and contact your veterinarian. In most cases the side effects will disappear when the drug is stopped but in rare cases it may be serious. For this reason, it is important to consult with your veterinarian. If you notice any serious side effects or others not mentioned in this insert, please inform your veterinarian.
