Previcox (firocoxib) 227 mg chewable tablets

Previcox is a veterinary nonsteroidal anti-inflammatory drug (NSAID) used to help manage pain and inflammation in dogs, most often with osteoarthritis. This page summarizes key label-based information about Previcox 227mg for dogs, including dosing concepts, safety cautions, and handling. It also explains how prescription referral ordering works for people paying cash and those without insurance.

What Previcox 227mg for dogs Is and How It Works

Previcox contains firocoxib, an NSAID that targets cyclooxygenase-2 (COX-2), an enzyme involved in inflammatory pain signaling. By reducing prostaglandins (inflammation messengers), the medicine may lessen joint pain and improve comfort in chronic arthritis. COX-2 selectivity is intended to reduce inflammation while limiting effects on other prostaglandins that support the stomach lining and kidney blood flow, although risks still exist.

Ships from Canada to US. CanadianInsulin operates as a prescription referral service for prescription medications. The veterinary prescriber determines whether firocoxib is appropriate and how it should be used for the dog’s condition.

Who It’s For

This medicine is typically prescribed for dogs with pain and inflammation associated with osteoarthritis (degenerative joint disease). It is generally used when a veterinarian has confirmed a musculoskeletal condition and decided an NSAID is appropriate. Some clinics use NSAIDs as one part of a broader plan that can include weight management, controlled activity, physical rehabilitation, and other analgesics.

NSAIDs are not a fit for every dog. Veterinarians may avoid or use extra caution in dogs with a history of gastrointestinal ulceration or bleeding, kidney disease, liver disease, dehydration, or clotting disorders. Use may also be restricted around surgery or in dogs taking certain concurrent medications.

Dosage and Usage

Dosing for firocoxib is weight-based and should follow the product label and the veterinarian’s written directions. Previcox tablets are commonly given once daily, and the goal is the lowest effective exposure for the shortest duration consistent with the treatment plan. Chewable tablets are often administered with or without food; some dogs tolerate NSAIDs better when given with a meal, but veterinary instructions should guide administration.

Because this is a prescription NSAID, dosing should not be extrapolated from human medications or other veterinary products. When starting therapy, clinics often review current medicines and supplements, check recent lab results if available, and set expectations for monitoring. Prescription details may be confirmed with the veterinary clinic before dispensing.

Monitoring during NSAID therapy

Monitoring helps identify intolerance early and supports safer longer-term use. Owners are often advised to watch for appetite change, vomiting, diarrhea, dark or tarry stool, increased thirst, urination changes, unusual fatigue, or behavior changes that suggest discomfort. Veterinarians may recommend baseline and follow-up bloodwork to evaluate kidney and liver parameters, especially for older dogs or dogs on long courses. If concerning signs appear, the usual advice is to stop the NSAID and contact the veterinarian promptly, rather than giving additional doses or combining pain relievers.

Strengths and Forms

Previcox is supplied as oral chewable tablets (firocoxib). This listing focuses on the 227 mg tablet strength, which is typically selected when a dog’s calculated dose aligns with that presentation. Some pharmacies also list different bottle counts, and availability can vary by dispensing pharmacy and current sourcing.

The table below summarizes key product identifiers used for medication reconciliation and refill requests. Matching the active ingredient and strength helps reduce mix-ups with other NSAIDs.

Storage and Travel Basics

Store chewable tablets according to the package labeling, typically at controlled room temperature and protected from moisture. Keep the medication in its original container with the label intact, and store it where pets cannot access it. Because many chewable veterinary medicines are flavored, accidental ingestion can happen if the container is left within reach.

Quick tip: When traveling, carry the prescription label and keep tablets in the original bottle.

For pet medication organization and browsing related products by category, the Pet Medications hub can be used as a starting point. For any storage questions that are not answered on the label, a pharmacist or veterinary clinic can clarify whether temperature excursions are a concern for a specific lot.

Side Effects and Safety

As with other NSAIDs, the most common side effects are gastrointestinal. Vomiting, diarrhea, reduced appetite, or lethargy can occur and may be mild or can progress. More serious adverse events are less common but can include gastrointestinal ulceration or bleeding, kidney injury, and liver enzyme elevations. Risk can increase in dogs that are dehydrated, older, or have underlying kidney or liver disease.

Why it matters: Early recognition of NSAID intolerance can reduce the chance of severe complications.

Seek veterinary evaluation promptly if there are signs of bleeding (black stools, vomit that looks like coffee grounds), marked weakness, collapse, yellowing of the gums or eyes, or a sudden change in drinking or urination. When reporting side effects, include the exact product name and strength, including whether the dog is taking Previcox 227mg for dogs or another NSAID formulation.

Drug Interactions and Cautions

Drug interactions matter with NSAIDs because overlapping mechanisms can increase the risk of stomach ulceration, bleeding, or kidney stress. The most important caution is avoiding concurrent use with another NSAID (including aspirin in many cases) or with corticosteroids unless a veterinarian has directed a specific plan. Switching between anti-inflammatory medicines often requires a washout period determined by the prescriber.

Additional caution is common when NSAIDs are used alongside diuretics, ACE inhibitors, certain blood pressure medicines, anticoagulants, or other drugs that affect kidney perfusion or clotting. Always share a complete medication list, including supplements and any recent injections, when a dog is prescribed Previcox 227mg for dogs.

Compare With Alternatives

Several prescription NSAIDs are used for canine pain and inflammation, and selection depends on diagnosis, medical history, prior tolerance, and clinician preference. Common alternatives include carprofen, deracoxib, and meloxicam. Another class option is robenacoxib, which is widely used in cats and also has canine indications in some regions, depending on the labeled product.

This page is not a substitute for a veterinary plan, and it does not rank options by effectiveness. It can be helpful to review comparable NSAID product pages for formulation differences and general safety notes, such as Rimadyl Overview and Deramaxx Overview.

Pricing and Access

Costs for veterinary NSAIDs can vary based on strength, count, and dispensing pharmacy. Many people look for predictable cash-pay access, including those seeking Previcox 227 mg without insurance through a prescription referral workflow. When a prescription is required, the prescriber’s instructions determine the dispensed quantity and refills.
