quellin® is indicated for the relief of pain and inflammation associated with osteoarthritis and for the control of post-operative pain associated with soft tissue and orthopedic surgeries in dogs.

quellin® was designed to be easy to give: simple for dogs to chew and simple for your clients to administer to their dogs. It has a savory meat flavor with no animal proteins and is scored to enable simple dosing and uniform active-ingredient distribution.

WARNINGS: Keep quellin® soft chew tablets out of reach of children. Not for human use. For use in dogs only. Do not use in cats. All dogs should undergo a thorough history and physical examination before initiation of NSAID therapy.

Events involving suspected renal, hematologic, neurologic, dermatologic and hepatic effects have also been reported.
