Top 5 Prescription NSAIDs for Dogs in Canada (2025) — Veterinary-Approved Comparison of Carprofen, Meloxicam, Deracoxib, Firocoxib & Robenacoxib

Published on Thursday, August 21, 2025

This category organizes prescription nonsteroidal anti-inflammatory drugs (NSAIDs) for dogs by active ingredient — including carprofen, meloxicam, deracoxib, firocoxib and robenacoxib — to help Canadian pet owners and veterinary professionals compare efficacy, dosing and safety profiles. It covers branded and generic options (for example, Rimadyl and generic carprofen), ingredient-specific usage notes, typical dosing ranges, monitoring recommendations and common cautions. Because all of these products are prescription-only in Canada, the page emphasizes evidence-based differences that matter when making treatment choices for post-operative pain, acute injury or chronic osteoarthritis.

What the Research Says: Clear, Practical Evidence for Using NSAIDs in Dogs

A large body of veterinary research — including randomized controlled trials, pharmacokinetic investigations and comparative safety studies — supports the use of canine NSAIDs for postoperative pain and osteoarthritis when used under veterinary supervision. The findings consistently show meaningful reductions in pain and improved mobility, while also identifying predictable risk patterns (gastrointestinal, renal and hepatic) that can be minimized by correct dosing, appropriate patient selection and routine monitoring.

Randomized controlled trials report measurable improvements in pain scores and mobility for dogs with osteoarthritis treated with NSAIDs compared to placebo.

Pharmacokinetic studies explain why dosing frequency differs: drugs with longer half-lives (for example firocoxib/Previcox) often allow once-daily dosing while others may require different schedules.

Comparative clinical trials suggest broadly similar efficacy across several NSAIDs, with differences mainly in selectivity for COX-2, onset of action and tolerability.

Safety data identify common adverse events (vomiting, diarrhea, appetite changes) and less frequent but serious effects (renal or hepatic injury); these risks are reduced by baseline and periodic bloodwork.

Evidence-based best practices include using the lowest effective dose, avoiding concurrent use of multiple NSAIDs or corticosteroids, and individualizing treatment for age, concurrent disease and other medications.

Long-term management studies highlight that periodic reassessment (pain scoring, weight management, physical therapy) plus regular lab monitoring improves outcomes and reduces complications.

In the Canadian context, organizing prescription NSAIDs by active ingredient helps pet owners and clinicians pick the best fit for each dog. This page compares Rimadyl (carprofen), Metacam Oral Suspension (meloxicam), Deramaxx (deracoxib), Previcox (firocoxib) and Onsior (robenacoxib) across efficacy, dosing and safety notes. While individual needs vary, Previcox (firocoxib) is often considered a well-balanced choice for many dogs because of its COX-2 selectivity and convenient once-daily dosing; however the best option depends on the dog’s condition, lab results and veterinary advice.
