Product Description

Onsior is a nonsteroidal anti-inflammatory drug (NSAID) specifically formulated for cats to alleviate postoperative inflammation and pain. It is also effective in managing pain and inflammation associated with musculoskeletal disorders. Available in both injection and oral tablet forms, Onsior offers flexibility in administration to suit individual feline needs.

  • Administration -Onsior tablets are administered orally, either with or without food, for at-home care. In the event of vomiting on an empty stomach, it is recommended that the tablet be administered with food to mitigate discomfort. Tablets should always be given whole, without breaking them. After administering Onsior, it's essential to wash hands thoroughly. Pregnant women should take extra precautions by wearing gloves when handling the medication.

  • Effectiveness and Dosage -Typically, the effects of Onsior are observed within 1 to 2 hours post-administration. If a dose is missed, it should be given as soon as remembered. However, if it's close to the next scheduled dose, it's best to skip the missed one and resume the regular dosing schedule. Under no circumstances should two doses be given simultaneously, nor should extra doses be administered.

  • Side Effects -While Onsior is generally well-tolerated, there are potential side effects to be aware of. These include anorexia, lethargy, depression, vomiting, diarrhea, and, in rare cases, more severe conditions such as kidney disease, kidney failure, bleeding, or infection at the surgical incision site.

  • Monitoring and Precautions -Monitoring cats closely for signs of hypersensitivity or adverse reactions is crucial. Baseline blood and urine tests are recommended before initiating therapy, and periodic recheck appointments may be necessary for those on long-term treatment regimens. Onsior should be used with caution in cats with pre-existing conditions such as dehydration and severe renal, heart, or liver disease. It's contraindicated in pregnant or nursing cats and those under four months old. Additionally, it should be avoided in cats with known allergies to NSAIDs or gastrointestinal ulcers.

  • Interactions and Storage -Onsior should not be administered concurrently with other NSAIDs or corticosteroids. Caution is advised when used alongside diuretics, ACE inhibitors, or medications affecting kidney function. To prevent potential interactions, it's essential to inform the veterinarian about all medications, including vitamins, supplements, or herbal therapies. Tablets should be stored at room temperature (15C - 25C or 59F - 77F) away from moisture and sunlight.

In case of a suspected adverse reaction, contact the veterinarian immediately. If the veterinarian is unavailable, follow the prescribed directions for immediately reaching an emergency veterinary facility. Early intervention can be critical in managing any potential complications effectively.

Side Effects & Warnings

Do not use with pregnant or lactating pets or those suffering from ulcers. Do not increase the dose, frequency, or length of time you administer Onsior, unless directed by your vet. For cats and kittend 5.5lbs or over. Keep out of reach from children.




One tablet should be given once a day at the same time every day for up to 3 days. Cats weighing between 2.5 and 6 kg should be given 1 tablet daily. Cats weighing between 6 and 12 kg need 2 tablets daily. Your veterinarian will determine that correct dose of Onsior for your cat.
