What is Quellin carprofen - generic to Rimadyl?

Quellin is the first soft chewable formulation of carprofen (generic form of Rimadyl) which can make giving your pet's pain medication simple and easy. Each chewable is scored for effortless dosing and dogs love the meat flavor, so there's no need to hide the medication inside food or treats. Quellin requires a prescription from your veterinarian.


Dogs (6+ weeks of age)


  • Savory meat flavor and soft chewable tablet dogs take as a treat
  • Chewable tablet is scored for easy dosing
  • Can be given with or without food

How does quellin work?

Quellin is a non-steroidal anti-inflammatory drug (NSAID) that relieves pain and inflammation from osteoarthritis or recent surgery to improve your dog's mobility. In most dogs, improvement can be seen in a few days.


Federal law restricts this drug to use by or on the order of a licensed veterinarian. Keep out of reach of children. Not for human use. Consult a physician in cases of accidental ingestion by humans. For use in dogs only. Do not use in cats. All dogs should undergo a thorough history and physical examination before initiation of NSAID therapy. Appropriate laboratory tests to establish hematological and serum biochemical baseline data prior to, and periodically during, administration of any NSAID should be considered.

What is the most important thing I should know about quellin?

Quellin is a non-steroidal anti-inflammatory drug (NSAID) used to reduce pain and inflammation due to osteoarthritis and pain following surgery in dogs. Quellin is a prescription drug for dogs. It is available in a soft chewable tablet and is given to dogs by mouth.

What should I discuss with my veterinarian before giving quellin to my pet?

Tell your veterinarian about any NSAIDs or other medications your pet is currently being given.

How should quellin be given?

Quellin should be given according to your veterinarian's instructions. Your veterinarian will tell you what amount of quellin is right for your dog and how long it should be given. Most dogs will take quellin soft chewable tablets right out of your hand or the soft chewable tablet can be placed in the mouth. quellin may be given with or without food.

What are the potential side effects of quellin?

Quellin, like other drugs, may cause some side effects. Serious but rare side effects have been reported in dogs taking NSAIDs, including quellin. Serious side effects can occur with or without warning and in rare situations result in death. The most common NSAID-related side effects generally involve the stomach (such as bleeding ulcers), and liver or kidney problems. Look for the following side effects that can indicate your dog may be having a problem with quellin or may have another medical problem: decrease or increase in appetite; change in bowel movements (such as diarrhea, or black, tarry or bloody stools); change in behavior (such as decreased or increased activity level, incoordination, seizure or aggression); yellowing of gums, skin, or whites of the eyes (jaundice); change in drinking habits (frequency, amount consumed); change in urination habits (frequency, color, or smell); change in skin (redness, scabs, or scratching). It is important to stop therapy and contact your veterinarian immediately if you think your dog has a medical problem or side effect from quellin therapy. If you have additional questions about possible side effects, talk to your veterinarian.

What happens if I miss giving a dose of quellin?

Give your pet the missed dose of quellin as soon as you remember. If it is almost time for the next dose, skip the missed dose and resume the regular dosing schedule. Do not give your pet a double dose.

What happens if I overdose my pet on quellin?

If you suspect that your pet has received an overdose of quellin, consult your veterinarian or emergency veterinary clinic immediately.

What should I avoid while giving quellin to my pet?

Avoid giving your pet NSAIDs such as aspirin, deracoxib, etodolac, firocoxib, meloxicam, tepoxalin. Also, avoid giving your pet steroids including cortisone, dexamethasone, prednisone, triamcinolone while on quellin.

What other drugs will affect quellin?

Quellin should not be given with other NSAIDs (for example, aspirin, deracoxib, etodolac, firocoxib, meloxicam, tepoxalin) or steroids (for example, cortisone, dexamethasone, prednisone, triamcinolone). Tell your veterinarian about all medicines you have given your dog in the past, and any medicines that you are planning to give with quellin.

Rated 5 out of 5 by from Almost young again My 16 year old miniature schnauzer has terrible arthritis in his lower back. He was almost crippled. After the vet giving steroid/anti inflammatory shots for 3 days he prescribed rimadyl. I starting I ordering quellin from 800 pet meds and he feels so much better. He even try's to jump and play now. He has no stomach upset with this and I think he thinks he is just getting a treat. Little does he know it is a treat for both of us. His from less pain & mine from his feeling better.

Rated 4 out of 5 by from My oldest Cocker Spaniel Maxie seems to be a lot more relaxed on this medication. She has been taking it for almost a year now. It tastes like a treat for her, so she looks forward to taking it. She is 14 and has arthritis in her back. She seems to get around much better these days.

Rated 5 out of 5 by from Excellent product Our 13 1/2 year old cairn terrier has been getting arthritic. Quellin has definitely provided her with some relief, and she loves the chewable tablets. She "reminds" me if I don't give her her morning dosage after her first trip outside in the morning!

Rated 5 out of 5 by from Taste like a treat, works like a dream! I have two chihuahuas and both have arthritis issues. Remadyl was unaffordable for me as a single mother with two teens. 1800 Pet meds recommended we try the generic Quellin Carprofen. This medicine works better than the name brand and is in a treat like chew that my dogs love making it is easy to administer. The dogs love it so much that now when I say "It's time for medicine." it is like I am saying it's time for a goodie! Having two small dogs it is also nice and easy to break a pill in half. No more using a pill cutter. It just breaks in two like a soft cookie. I highly recommend this generic alternative.

Rated 2 out of 5 by from Disagreeable Flavor We purchased 4 bottles of quelling carprofen and now find that our yellow lab will not take the medication willingly. She does not like the tablets flavor, making administering the medication difficult.

Rated 5 out of 5 by from Better deal! We have 2 dobermans. One had knee replacement and may need the other done. Our other has hip and ankle issues so pain medicine that helps was costly so we tried this brand and it works GREAT! One case I know of that they didn't substitute quality for. Price

How do I get the prescription to you?

Asked by: Kathleen
The easiest way is to go ahead and order the medication and provide your veterinarian's information. PetMeds will then send a fax to your veterinarian for approval. Your vet then sends the prescription back to PetMeds and your medication ships to you. Your vet may ask for the written script back, so be prepared for that.

How much queiiin should I give my 25 lb Pug?

Asked by: Parley
The proper dosage is 2 milligrams per pound of body weight. In your pet"s case, that would be 50 milligrams per day. The dosage can be given as a single dose once a day(two 25mg chewable tablets) or in two equally divided doses 12 hours apart(one 25mg chewable tablet every 12 hours). My 13yr old Basset Hound has osteoarthritis in his right shoulder, he seems to get better, more consistent relief with the twice a day dosing schedule. I hope this reply is helpful to you.
