What is Onsior for Cats?

Onsior for Cats is a non-steroidal anti-inflammatory drug (NSAID) that relieves pain and reduces inflammation associated with orthopedic and soft tissue surgery. The small, yeast-flavored tablets are favored by cats and are easy to administer. Onsior for Cats is available in a 3-pack of 6 mg tablets in a blister packet. Onsior for Cats requires a prescription from your veterinarian.

For:

Cats (4+ months of age, weighing 5.5+ lbs)

Benefits:

  • Single dose quickly alleviates acute pain for 24 hours
  • Relieves pain associated with orthopedic and soft tissue surgery
  • Tasty yeast-flavored tablets accepted by most cats
  • Available in a 3-pack blister packet

How does Onsior for Cats work?

Onsior contains the active ingredient robenacoxib, an NSAID (non-steroidal anti-inflammatory drug) that targets the COX-2 enzyme that causes pain. It spares the COX-1 enzyme to protect your cat's gastrointestinal tract and blood platelet functions. The tablet is quickly absorbed from the gastrointestinal tract and is effective for 24 hours.

For cats only. Not for human use. Do not use with pregnant or lactating cats or those suffering from ulcers. Do not increase the dose, frequency, or length of time you administer Onsior for Cats, unless directed by your vet. Keep out of reach of children and pets. In case of accidental overdose, contact a health professional immediately.

Onsior for Cats is rated 4.2 out of 5 by 6.
Rated 1 out of 5 by from No results My cat has a leg injury and ONSIOR 6mg once a day for 3 days did nothing to relieve my cats leg pain, If there was a star less than one I would give this medicine a NEGATIVE ONE !!!!!!!!

Rated 5 out of 5 by from Arthritis in my 7 yr old cat's shoulder This is the 2nd time Tabitha has been prescribed Onsior for arthritic pain in her shoulder. The last time she did 2 rounds of medication 3 weeks apart, so 6 tablets total. That was in September. It is now almost May and she just started showing signs that she was hurting again. She has had no adverse effects anytime she has to take this medicine and within a few hrs it is obviously working to alleviate her pain. I think considering how infrequently she needs it that the price is worth the relief she gets.

Rated 5 out of 5 by from My cats thought it was a treat! After my girls got fixed, the Vet sent us home with a few of these. I just held the pill in the palm of my hand, and they licked it up (even my little picky britches!). I didn't have to shove it down their throat or trick them into taking it!!! I really appreciated this. As far as pain management goes, they seem to be acting like themselves, and not hunkered over in pain or anything like that. I would recommend this for sure!

Rated 5 out of 5 by from Excellent pain medication My cat has Vaccination fibrosarcoma which is a tumor that is growing aggressively due to vaccinations. She does not have much time left due to the size of this tumor (larger than a soft ball) but this medication allows her to walk and eat free of most pain.

Rated 5 out of 5 by from Works well for pain My cat had a soft tissue injury on her front paw. This medication helped reduce the inflammation and helped with her pain. The injury is mostly resolved now but occasionally she has pain in that foot, so I keep this on hand. She doesn't mind the taste. I give it to her with a few pieces of dry food and she just licks it out of her food bowl. I'm so glad there is finally something for cats that have pain.

Rated 4 out of 5 by from Works wonders for my cat who has arthritis in his low back. 4 stars because of the high price!

Does this medication last 24hrs? It doesn't seem to last that long with my cat who had his arm amputated.

Asked by: Valerie G88
Onsior is quickly absorbed from the gastrointestinal tract and is effective for 24 hours. It is normally dosed once daily, and should not be taken more often than prescribed by your cats vet.

Is this ok to give to a 9 wk old kitten?

my kitten was bitten by an older cat and now has an abscess. Has been incised by a vet, but it has gotten very large again. Thanksgiving weekend, but I know he is hurting. I may be able to get this at the pet store.

Onsior is a prescription medication so your vet will need to prescibe it. Onsior is also only approved for cats 6 months of age and older.

What are normal (non-concerning) side effects of Onsior?

I can find lots of information about adverse/dangerous side effects of Onsior in cats but nothing about what can be commonly expected - i.e. sleepiness or nervousness, etc.

can onsior be given for more than 3 days? If so, can it be used as a daily medication?

Asked by: Anonymous
It's approved for long term use in Britain. When my cat had a really bad soft tissue injury my vet had me give it to her for several weeks to reduce the inflammation and pain. It worked really well. We tested her blood regularly to make sure she wasn't having any problems from being on it for so long. She was fine. No problems at all. I still give it to her occasionally if she limps or if I suspect she is in pain. I would recommend a blood test after a week just to make sure your cat is ok.
