367813
Onsior 40mg for Dogs is a prescription-only non-steroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation in dogs. It contains the active substance robenacoxib, which is a selective cyclooxygenase-2 (COX-2) inhibitor. This medicine is commonly prescribed by vets to manage pain associated with osteoarthritis and musculoskeletal disorders in dogs.
Each tablet contains 40mg of robenacoxib and is designed for once-daily oral administration. Onsior tablets are flavoured to aid with administration and are scored to allow accurate dosing based on the dog’s weight. They are authorised for veterinary use in the UK and have been shown to be effective for the management of chronic and acute pain.
How 40mg Onsior Works
Onsior 40mg contains robenacoxib, a member of the coxib class of NSAIDs. It works by selectively inhibiting the enzyme cyclooxygenase-2 (COX-2), which plays a key role in producing prostaglandins responsible for pain and inflammation. By blocking COX-2, robenacoxib reduces the production of these chemicals at the site of injury or inflammation.
Unlike traditional NSAIDs, Onsior has minimal effect on COX-1, the enzyme involved in maintaining normal functions of the gastrointestinal tract, kidneys, and blood clotting. This selectivity helps reduce the risk of gastrointestinal and renal side effects often associated with NSAID use in dogs.
Onsior begins to act rapidly, with effects typically observed within one to two hours of administration. The drug accumulates preferentially at sites of inflammation, allowing for targeted relief of pain while limiting exposure to unaffected tissues.

Managing Arthritis Pain in Dogs
Osteoarthritis, often referred to simply as arthritis, is a common condition in older dogs but can also occur in younger animals due to injury, joint abnormalities, or genetic predisposition. It is a progressive, degenerative joint disease characterised by the breakdown of cartilage, inflammation of the joint lining, and reduced mobility.
Dogs with arthritis may show signs such as:
-
Stiffness when rising or after rest
-
Reluctance to walk, jump, or climb stairs
-
Limping or lameness
-
Reduced interest in exercise
-
Irritability or changes in behaviour
-
Muscle loss due to disuse of affected limbs
Pain associated with arthritis can significantly impact a dog’s quality of life. Chronic inflammation leads to further joint damage, and untreated pain can affect appetite, sleep, and general well-being.
40mg Onsior helps manage arthritis by reducing inflammation and relieving associated pain. By decreasing discomfort, it can help dogs regain mobility, engage in physical activity, and maintain a better overall condition. Regular treatment may slow the progression of joint deterioration when combined with other management strategies such as weight control, physiotherapy, and dietary supplements.
Dosage and Administration
Onsior 40mg tablets are prescribed based on the weight of the dog. The recommended dose is 1 mg/kg of body weight, once daily, for up to 6 days for acute musculoskeletal disorders. For long-term use in osteoarthritis, the course and duration are determined by the prescribing vet based on individual needs.
Tablets should be given orally, either with or without food. However, it is advised to administer Onsior at the same time each day to maintain consistent blood levels. Tablets should not be divided unless needed to achieve the correct dosage, and care should be taken to follow the vet’s instructions precisely.
Onsior should not be used in dogs under 2.5kg in body weight or younger than 3 months of age. The tablets are available in different strengths (5mg, 10mg, 20mg, and 40mg), so it is important to use the correct strength to ensure accurate dosing.
Storage and Handling
Store Onsior tablets below 30°C in the original packaging to protect them from moisture and light. Keep out of the reach and sight of children and animals. Do not use tablets that are past their expiry date.
If a tablet is only partially used, it should be returned to the blister and used within the timeframe specified by the manufacturer or your vet. Wash hands after handling the medication.
Precautions and Side Effects
While Onsior is generally well-tolerated, it may cause side effects in some dogs. Common adverse effects include:
-
Vomiting
-
Diarrhoea
-
Loss of appetite
-
Lethargy
These effects are usually mild and resolve without intervention. In rare cases, more serious reactions such as kidney or liver issues may occur. Dogs with pre-existing kidney, liver, or gastrointestinal conditions should be monitored closely, and use should be avoided unless advised by a vet.
Onsior should not be used in animals with hypersensitivity to robenacoxib or other NSAIDs. It should not be administered at the same time as other anti-inflammatory drugs, including corticosteroids or other NSAIDs, as this increases the risk of adverse effects.
Pregnant or lactating dogs should not be treated with Onsior unless specifically advised by a vet. Regular veterinary check-ups are recommended during long-term treatment to assess the dog’s response and monitor for any potential side effects.
