Onsior® Tablets for Cats

What Onsior Is and How It Works

Onsior® is robenacoxib, a nonsteroidal anti-inflammatory drug (NSAID) for cats. It helps reduce pain and inflammation after common feline surgeries and with short-term musculoskeletal discomfort.

We verify prescriptions with your prescriber when required, and licensed Canadian pharmacies dispense your order.

This medicine works by selectively inhibiting cyclooxygenase-2 (COX-2), an enzyme linked to inflammatory pathways. It can provide targeted relief with a short daily course when directed by a veterinarian. For a practical overview of uses and expectations, see our guide What Is Onsior Cat Medicine Used For.

Who It’s For

Veterinarians may prescribe this treatment for cats needing short-term control of postoperative pain and inflammation. It may also be used for brief management of musculoskeletal or osteoarthritic discomfort as directed.

Onsior Cat is not for kittens under a labeled age threshold or underweight cats. Avoid use in breeding, pregnant, or nursing queens unless a veterinarian decides the benefits outweigh risks. Cats with dehydration, bleeding disorders, gastrointestinal ulcers, kidney disease, or heart disease may need extra caution.

Dosage and Usage

Dosing is veterinarian-directed. Label instructions typically involve a once-daily schedule for a limited number of days. For surgical pain, the first dose may be timed around the procedure, then continued briefly afterward. For other indications, the course remains short unless your veterinarian advises differently. The standard advice is to use the lowest effective dose for the shortest necessary duration.

Give tablets as directed, ideally at the same time each day. If your cat vomits shortly after dosing, contact the clinic for guidance. Do not combine with other pain medicines unless specifically instructed. If you have questions about onsior 6mg for cats, ask your veterinarian to confirm timing, duration, and monitoring.

Helpful tips: Offer a small water rinse after dosing if your cat tolerates it. Keep an eye on appetite, activity, and litter box habits. If your cat refuses the tablet, speak with your veterinarian about administration strategies before altering the plan.

Strengths and Forms

Flavor-coated onsior 6 mg tablets are commonly used for cats. The treatment is also available as an injectable solution administered by veterinarians for perioperative use.

Availability can vary by clinic and pharmacy. Strengths and packaging may differ by market. If a specific presentation is not in stock, your prescriber may suggest a suitable alternative option.

Missed Dose and Timing

If you miss a dose, give it when you remember unless it is close to the next scheduled time. Do not double up to make up for a missed dose. If multiple doses are missed during a short course, contact the clinic to ask whether to restart or discontinue.

Because this is often a brief regimen, timing clarity is important. Keep a simple calendar or phone reminder so you do not extend therapy accidentally.

Storage and Travel Basics

Store tablets in the original blister until use, and keep them dry. Room-temperature storage away from moisture and direct sunlight is generally recommended. Keep out of reach of children and pets.

For travel, carry the original labeled package and a copy of the veterinary prescription. If you cross borders with your pet, keep documentation accessible. Pack doses in a secure container within your carry-on so you can administer them on schedule. Dispose of unused tablets according to local guidance or return them to a pharmacy take-back program.

Benefits

This medicine targets inflammatory pathways associated with pain. A once-daily schedule can simplify short courses chosen by veterinarians. Palatable, small tablets may support easier dosing for many cats.

Short treatment windows can help limit overall NSAID exposure. The approach may be paired with non-drug strategies like rest, a quiet recovery space, and gentle handling.

Side Effects and Safety

Discuss onsior 6 mg for cats side effects with your veterinarian before starting therapy. Stop the medicine and seek veterinary care if serious problems appear.

• Digestive changes: vomiting, soft stool, diarrhea
• Appetite changes: reduced interest in food
• Behavioral changes: lethargy, restlessness
• Urinary changes: altered drinking or urination patterns
• Less common: gastrointestinal ulceration or bleeding signs

Serious risks can include kidney complications, liver enzyme changes, or gastrointestinal perforation or bleeding, particularly with concurrent NSAIDs or steroids. Cats with dehydration or preexisting kidney or gastrointestinal disease may be at higher risk. Seek prompt veterinary advice if you notice black or bloody stool, persistent vomiting, marked inappetence, jaundice, or unusual bruising.

Drug Interactions and Cautions

Tell your veterinarian about all medicines and supplements your cat receives, including over-the-counter items. Interactions may occur with other NSAIDs, corticosteroids, anticoagulants, certain blood pressure agents, diuretics, or nephrotoxic drugs. Use caution with dehydrated cats or those with renal, hepatic, or gastrointestinal disease. The phrase robenacoxib 6 mg for cats often appears in references; your veterinarian will confirm the appropriate product and strength for your cat.

Do not combine with aspirin or other pain relievers unless your veterinarian specifically approves. Avoid giving herbal supplements without veterinary guidance, especially if they may affect bleeding or kidney function.

What to Expect Over Time

Results vary by cat and condition. Many cats show improved comfort and activity during the short treatment window. You may notice changes in walking, jumping, or grooming behaviors as discomfort lessens.

Continue monitoring for appetite, drinking, and stool consistency. If pain returns after the course ends, contact your clinic to discuss next steps. A veterinarian may consider non-drug measures, re-evaluation, or other treatments based on your cat’s overall health.

Compare With Alternatives

Veterinarians may use an injectable perioperative option for rapid control. One example is Onsior Solution, given in a clinic setting as part of a surgical plan. For ongoing support in select cases, oral meloxicam may be considered; see Metacam Oral Suspension and discuss suitability with your veterinarian.

Availability and Substitutions

Supply can vary. If your requested presentation is unavailable, a veterinarian may recommend a comparable alternative or a clinic-administered option. In some settings, injectable solutions or different NSAID classes may be suggested based on clinical judgment.

If substitution is advised, confirm the plan, duration, and any laboratory monitoring. Never switch NSAIDs without your veterinarian’s direction.

Patient Suitability and Cost-Saving Tips

This treatment may suit adult cats needing short-term pain control after surgery or with intermittent musculoskeletal flares. It may not be appropriate for cats with active gastrointestinal ulceration, significant kidney disease, or bleeding disorders. Always review the medical history and any prior NSAID reactions with the clinic.

For budgeting, ask about multi-pack fills when appropriate. Set refill reminders ahead of planned procedures so you have tablets on hand when your veterinarian recommends them. Review the What Is Onsior Cat Medicine Used For article for a quick refresher before you reorder.
