Research brief

Medication Research Insights

A source-aware map of what to know, what is uncertain, and what to verify with your veterinarian.

Source Backed Signals

What to know

Evidence-backed context Limited

Roxee has limited cited overview evidence for Robenacoxib; use the official documents and your veterinarian's instructions for product-specific decisions.

Source: openFDA case USA-USFDACVM-2026-US-014416

Safety signal coverage Reported signals

32 tracked reaction signals; 32 reported cases; 21 serious reports; 1 species group. These are reporting and label-derived signals for interpretation with a veterinarian.

Source: openFDA case USA-USFDACVM-2026-US-014416

Interpretation guardrail Not causation

Adverse-event reports help form a watch list, but they do not prove the medication caused the reaction and they are not a risk ranking between medications.

Evidence tension

Stronger signal Label / review

Official labels, package inserts, and reviewed summaries carry more weight than isolated reports.

Source: openFDA case USA-USFDACVM-2026-US-014416

Weaker signal Reported data

Case reports and openFDA terms are useful for pattern awareness, but they are incomplete, can include multiple exposures, and do not estimate an individual pet's probability of harm.

Reaction signal map

Most reported reactions Top terms

Unsteady walking (ataxia) (1 reports), Loss of appetite (1 reports), Bone marrow suppression (1 reports), Bloody diarrhoea (1 reports), Blood in vomit (1 reports)

Domestic Shorthair (5), Cat (other) (1), Domestic Longhair (1), Russian (1). These are report metadata, not proof that a breed is at higher risk.

What your vet may verify

Fit for this patient Vet check

Verify whether Robenacoxib fits the pet's species, current diagnosis, age, weight, organ status, pregnancy/lactation status, and concurrent medications.

Evidence limitations Evidence review

Separate label-backed warnings from adverse-event reports and owner observations before changing the plan.

What to watch next

Watch list Owner-safe

Do not use in animals with known hypersensitivity to NSAIDs, gastrointestinal ulcers, or severe rena, Not recommended for pregnant or lactating animals, wobbly/unsteady walking, Loss of appetite, Bone marrow suppression

Call sooner if Escalation

Repeated vomiting or diarrhea. Severe lethargy (hard to wake, very low energy). Collapse or fainting.

Bottom line: Use this Robenacoxib brief as a structured watch list and source map, not as a reason to start, stop, or change treatment without your veterinarian.
