About firocoxib (the active ingredient)

Non-steroidal anti-inflammatory drug (NSAID, coxib — COX-2 selective).

How it works

NSAIDs reduce prostaglandin production by inhibiting the cyclooxygenase (COX) enzymes [5]. In canine whole-blood assays firocoxib is 384-fold more selective for COX-2 than COX-1, and its elimination half-life of about 8 hours allows once-daily dosing [5].

Key safety points

  • Dogs with known hypersensitivity to firocoxib should not receive it (Previcox label) [4].
  • The Previcox label warns against doses above 5 mg/kg in puppies under seven months old, and against use together with other NSAIDs or corticosteroids [4].
  • Serious adverse reactions to this drug class can occur without warning [4].
  • Equioxx is for horses only and must not be used in horses intended for human consumption [6].
