Onsior Tablets for Dogs

What Onsior is used for

Onsior (robenacoxib) is a coxib-class NSAID licensed for two uses in dogs: pain and inflammation from chronic osteoarthritis, and pain and inflammation associated with soft tissue surgery.

Available strengths

5mg, 10mg, 20mg and 40mg tablets, matched to your dog’s bodyweight by your vet, packs of 30.

How it’s given

Given once daily on an empty stomach (at least 30 minutes before or after food) — tablets should not be broken or divided. For osteoarthritis, your vet will re-evaluate treatment after around 10 days.
