What is Onsior for Dogs?

Onsior for cats and dogs is an anti-inflammatory drug used to treat pain and inflammation in acute and chronic musculoskeletal disorders in cats or dogs. Onsior for dogs is typically used to treat symptoms of osteoarthritis. 

Please note, Onsior should not be used in dogs under 3 months of age or weighing less than 2.5 kg, nor should it be used in cats weighing less than 2.5 kg or under 4 months of age. Onsior also must not be used in lactating animals.

How Does Onsior Work?

Onsior for dogs is a non-steroidal anti-inflammatory drug (NSAID) that blocks cyclooxygenase 2, an enzyme that produces prostaglandins that cause pain and inflammation. This blockage helps reduce pain and inflammation caused by musculoskeletal disorders, surgery, and osteoarthritis.

How long does it take for Onsior to work?

Once administered, Onsior begins to work within 1-2 hours and has been shown to reduce pain and improve mobility in pets quickly. 

Onsior for Dogs Side Effects

As with any prescription medicine, there are some potential side effects when treating your pet with Onsior. However, these side effects tend to be mild and go away without needing treatment. These adverse reactions include:

  • - Vomiting
  • - Diarrhoea
  • - Blood in stool
  • - Decreased appetite

More information about the side effects relating to treatment with Onsior can be found in the provided product data sheet or should be explained by your vet. If you are concerned about any reactions your pet has while taking Onsior, consult with your vet for further advice. 

How to Administer Onsior Tablets

Onsior tablets are to be administered orally at least 30 minutes before or after your pet has eaten to ensure efficacy and as per your vet's instructions. They may be given a little bit of food to aid in administering. 

Can Onsior be crushed?

You should not attempt to crush Onsior tablets or split them, as this can impact their effectiveness. They are, however, palatable tablets which most cats or dogs easily accept.

Can Onsior be used long-term?

Onsior can be used long-term to treat chronic musculoskeletal disorders in dogs or cats. However, this must only be done under strict monitoring by your vet and under their advice. 

Can You Buy Onsior For Dogs Without Vet Prescription?

All Onsior products are prescription-only veterinary medicine, which means they can only be purchased using a valid, in-date prescription from your vet. You can learn more about ordering a prescription medicine for your pet from Pet Drugs Online on our prescription information page. For your pet's safety, always be wary of any organisation offering to sell Onsior or any other prescription-only veterinary medicines without a prescription.

Please note, while we have an onsite vet to oversee the sales of prescription medicines, we do not offer veterinary consultations or advice.
