Onsior is used in cats and kittens for the control of postoperative pain and inflammation associated with orthopedic surgery. It can also be prescribed for other kinds of pain. The maximum duration of therapy is 3 days. The active ingredient in Onsior is robenacoxib that targets the COX-2 enzyme that causes pain. It spares the COX-1 enzyme to protect your cats gastrointestinal tract and blood platelet functions. The tablet is quickly absorbed from the gastrointestinal tract and is effective for 24 hours.

Robenacoxib

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.
