Prescribing overview
Rimadyl is canine-labeled; do not use in cats.
Key prescribing checks
- Rimadyl is labeled for dogs and specifically warns against use in cats.
- Review renal, hepatic and gastrointestinal disease, hydration status and concurrent medications before use. Baseline and follow-up assessment should follow the veterinarian’s plan.
- Avoid concurrent NSAIDs or corticosteroids unless a veterinarian has explicitly assessed the situation and applicable label instructions.
- Vomiting, reduced appetite, black stools, increased thirst or jaundice can indicate serious adverse effects and require prompt clinical contact.
Uses by species
Approval and evidence apply to the named product, species, route and indication. An extra-label use requires its own prescribing assessment; a human indication is not an animal approval.
Dogs
US veterinary approved labelOsteoarthritis pain/inflammation and postoperative pain after soft-tissue/orthopedic surgery
Assess individual benefit and toxicity risk.
Use / indication source ↗Pharmacology & pharmacokinetics
Mechanism and clinical role
Cyclooxygenase inhibition reduces prostaglandin production; protective renal/GI prostaglandins may also be affected.
Absorption, distribution, metabolism and elimination
Dogs: oral bioavailability >90%, peak 1–3 hours, mean terminal half-life approximately 8 hours; hepatic biotransformation with mainly fecal metabolite elimination.

Contraindications & cautions
Contraindications identify circumstances where the source says a product should not be used. Precautions call for assessment or monitoring. Interactions identify combinations to review. They are distinct categories; this summary does not replace a full interaction check or the current product label.
Rimadyl
US canine chewable label.
Contraindications · when not to use
- Previous carprofen hypersensitivity.
Precautions & monitoring
- Do not use in cats. GI, kidney and liver toxicity risks increase with dehydration or organ dysfunction. Bleeding-disorder use is not recommended; young-puppy and reproductive safety unestablished.
Safety sources checked: . Selected label information; independent veterinary or veterinary-pharmacy review remains pending. A label for dogs, cats, horses or humans does not establish safety for another species.
Adverse effects
GI ulceration/bleeding, kidney injury and hepatic toxicity can be serious; vomiting and appetite loss may be early signs.
These are selected source-reported effects, not incidence estimates or an exhaustive list. Spontaneous postmarketing reports do not by themselves establish frequency or causality.

Client counseling

Brands, formulations & ingredient identity
Active ingredients
Carprofen
Rimadyl chewables identify carprofen; formulations and routes must still be checked against the prescription.
An ingredient match across carprofen products does not authorize substitution or establish matching strength.
Shared ingredients do not establish interchangeable concentrations, routes, release properties, species labeling or regional availability.
