ONSIOR® Tablets for Cats (robenacoxib)

Help get them from hospital to home comfortably

With demonstrated efficacy for use up to a maximum of 3 days, Onsior should be your NSAID of choice for spay/neuter pain relief.

ONSIOR is an excellent option because it's:

  • the only FDA-approved oral NSAID for cats and the #1 feline NSAID brand in the US1
  • convenient - many cats require a single tablet to obtain the full daily dose
  • rapidly absorbed, persists at the site of inflammation, and then rapidly cleared from bloodstream*2

*Clinical relevance unknown
