Onsior for Dogs 40mg

Onsior for Dogs is a non-steriodal anti-inflammatory medication which helps to reduce fever, pain and inflammation.

The active ingredient in Onsior is Robenacoxib. It is part of the coxib class of non-steriodal anti-inflammatory drugs (NSAID) which primarily helps with the treatment of pain and inflammation associated with osteo-arthritis in dogs.

Onsior is a prescription item and will be sent once a valid prescription is received. Please follow the instructions given by your vet.

What is Osteo-arthritis? Osteo-arthritis is a term which refers to a form of chronic joint inflammation caused by deterioration of joint cartilage. This can also be known as degenerative joint disease which is the permanent deterioration of the cartilage surrounding the joints. Older dogs are at higher risk of developing this condition.

They are supplied in individual 5mg, 10mg, 20mg and 40mg tablets or packs of 28. They are a round, beige tablet flavoured with artificial beef to make administration easier but most dogs will voluntarily take this medication.

How many tablets does my dog need? The recommended dose of Onsior is 1mg per kg bodyweight daily (with a range of 1-2mg per kg). For example:

2.5-5kg - 1x 5mg tablet

5-10kg - 1x 10mg tablet

10-20kg - 1x20mg tablet

20kg-40kg - 1x 40mg

40kg+ - 2 x 40mg 

 It is advised to issue Onsior at the same time every day.

Do not administer with food. Studies have shown that giving Robenacoxib without food or at least 30 minutes before or after food had better efficacy.

Do not divide or break tablets.

Wash hands after handling medication.

This is a prescription item and will be sent once a valid prescription is received.

If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.

I regularly use Pet Drugs Online to buy both prescription items and syringes etc. for my diabetic dog & Advocate for all my dogs. The prices are so much cheaper than I can buy from my vet, even taking into consideration the vet fee for writing out a prescription & the delivery charge for my order. It's easy to scan a copy of the prescription from your vet & send with your order too. Very pleased with this site & would highly recommend.
