Onsior (robenacoxib) tablets for dogs

Onsior Dog is a prescription nonsteroidal anti-inflammatory drug (NSAID) used in veterinary medicine to help control pain and inflammation in dogs. This page summarizes key basics—how it works, typical use patterns, and safety considerations—so the product listing is easier to understand. Access through CanadianInsulin may include US shipping from Canada and cash-pay options for those without insurance.

What Onsior Dog Is and How It Works

Onsior contains robenacoxib, an NSAID that reduces inflammatory signaling by blocking cyclooxygenase enzymes; it is often described as COX-2 selective (an inflammation-linked enzyme). Lowering prostaglandins can decrease swelling and discomfort, which may improve mobility and post-procedure comfort when prescribed by a veterinarian. CanadianInsulin operates as a prescription referral platform.

This product is generally used when a veterinarian decides an anti-inflammatory medicine is appropriate for short-term or ongoing pain control. As with other NSAIDs, the expected benefit must be balanced against known risks to the stomach and intestines, kidneys, and liver. For related veterinary options, the Pet Medications category is a browseable list of prescription and non-prescription items.

Who It’s For

This medication is prescribed for dogs when a clinician determines that an NSAID is appropriate for pain and inflammation management. Common real-world reasons include osteoarthritis-related discomfort and perioperative pain control, but the exact approved indications can vary by country label and the specific product supplied. The veterinarian’s diagnosis and the dispensing label should be treated as the primary directions for use.

Onsior Dog is not appropriate for every dog. NSAIDs are commonly avoided or used with extra caution in pets with a history of gastrointestinal ulceration or bleeding, significant kidney or liver disease, dehydration, or known sensitivity to NSAID therapy. Special populations (very young animals, breeding animals, pregnancy, and lactation) may require additional risk assessment. Condition hubs such as Canine Osteoarthritis and Canine Pain can help organize related products and background reading.

Dosage and Usage

Veterinarians typically dose robenacoxib based on the dog’s body weight and the condition being treated. Dosing schedules are commonly once daily, but the duration and whether the dose is short-course (for example, around a procedure) or longer-term (for chronic joint disease) depends on the prescribing plan and the official labeling for the product supplied. Onsior Dog tablets are given by mouth; some labels specify giving it without food or separated from meals, so the dispensing instructions should be followed closely.

If a dose is missed, standard veterinary guidance for many daily medicines is to give the next dose at the usual time rather than doubling up, unless the prescriber advises otherwise. Monitoring plans may differ for short courses versus ongoing therapy; for longer treatment, clinics may periodically reassess comfort, appetite, stool quality, hydration, and lab work. Background context on joint disease is available in Understanding Arthritis In Dogs, and broader awareness topics are covered in Juvenile Arthritis Awareness.

Why it matters: Combining NSAIDs or mixing with steroids can increase adverse-effect risk.

Strengths and Forms

Robenacoxib for dogs is commonly supplied as oral tablets in multiple strengths so the veterinarian can match dosing to the dog’s size. Depending on the market and supplier, strengths may include 5 mg, 10 mg, 20 mg, and 40 mg tablets; the exact presentation and packaging can differ. Availability can also vary over time, and substitutions between strengths should not be made without the prescriber’s direction.

Some clinics also use injectable robenacoxib formulations for perioperative pain control, administered by veterinary professionals. That injectable form is not the same as an at-home tablet regimen, and dosing, timing, and monitoring differ. For readers comparing species-specific products, Onsior For Cats Overview explains how labeling and use considerations can differ by animal.

Storage and Travel Basics

Store tablets exactly as shown on the pharmacy label and manufacturer packaging. Many solid oral medicines are kept at controlled room temperature and protected from moisture and heat, but the product-specific insert should be used as the final reference. Keeping tablets in the original blister or bottle can help maintain stability and reduce dosing errors, especially when multiple pet medicines are in the home.

For travel, keep the medication in its labeled container and bring a copy of the prescription or dispensing paperwork. Planning ahead helps avoid missed doses, particularly when time zones or boarding schedules change. If a dog is prone to chewing, store the package in a secure location because accidental ingestion can cause serious harm. A simple handling step is to wash hands after giving the dose and to keep medications away from children and other animals.

Quick tip: Use an account note to track the start date and remaining tablets.

Side Effects and Safety

Like other NSAIDs, robenacoxib can cause gastrointestinal side effects. Mild signs may include reduced appetite, nausea, soft stool, vomiting, or decreased energy. Some dogs tolerate treatment well, while others show effects early in therapy or after a dose change. Because these signs can overlap with other illnesses, changes should be documented and shared with the veterinary clinic.

More serious reactions are less common but require urgent veterinary assessment. Warning signs can include repeated vomiting, blood in vomit, black or tarry stool, severe diarrhea, marked lethargy, collapse, yellowing of the eyes or gums, or a sudden increase in thirst and urination that could suggest kidney stress. When required, prescriptions are confirmed with the prescriber before dispensing through partner pharmacies.

For dogs needing another NSAID, clinics may compare options based on history and lab results. A related overview of another veterinary NSAID is available in Deramaxx For Dogs Guide, which can help frame class-wide cautions and monitoring topics.

Drug Interactions and Cautions

NSAIDs can interact with other medicines that affect the stomach lining, bleeding risk, kidney blood flow, or fluid balance. A common caution is avoiding concurrent use with other NSAIDs or corticosteroids (such as prednisone) unless a veterinarian explicitly directs that combination. Additional interaction concerns may exist with anticoagulants, certain heart and blood-pressure medications, diuretics, and drugs that are hard on the kidneys.

Clinical risk can increase in dehydration, low blood pressure, or reduced kidney perfusion, including around anesthesia, vomiting/diarrhea illnesses, or poor water intake. Clinics may recommend pausing or reassessing NSAID therapy during acute illness, depending on the case. For any dog taking multiple prescriptions, an up-to-date medication list (including supplements) helps the prescriber evaluate avoidable overlaps, especially when more than one clinician is involved in care.

Compare With Alternatives

Veterinarians choose among several NSAIDs and pain-control approaches based on diagnosis, previous response, comorbidities, and monitoring capacity. Alternatives within the NSAID class include carprofen, meloxicam, firocoxib, and deracoxib, each with different labeled indications, dosing guidance, and available dosage forms. The comparison is rarely one-size-fits-all; prior gastrointestinal intolerance or kidney concerns can shift the risk-benefit discussion.

When reviewing options on the site, related listings include Rimadyl Details and Metacam Details. Onsior Dog may also be considered alongside non-NSAID strategies (such as rehabilitation or weight management) that a veterinary clinic can incorporate into a broader plan. Product selection and any switch between NSAIDs should be directed by a veterinarian to reduce the chance of adverse effects.

Pricing and Access

Costs for veterinary prescriptions can vary by strength, quantity, and dispensing source. For some households, cash-pay access can be helpful when coverage is limited or absent, including situations without insurance. Prescription status still applies: a valid veterinary prescription is typically required, and the dispensing label should be reviewed for dosing instructions and refills.

CanadianInsulin coordinates prescription intake and routes eligible requests to licensed Canadian pharmacies for dispensing. Licensed Canadian pharmacies dispense the medication after prescription review. When documentation is incomplete, additional confirmation steps may be required before the pharmacy can proceed. Program availability and site-wide updates are listed on Site Promotions, when applicable.

Authoritative Sources

For the most accurate details on indications, contraindications, and administration directions, the official product labeling should be used alongside veterinary guidance. These references can be helpful when reviewing class warnings, monitoring recommendations, and country-specific labeling differences, especially if a dog has other health conditions or takes multiple medications.
