Does your dog limp, show signs of pain, or tire easily?

OA can hurt your dog in more ways than one.RIMADYL can help.

The pain of osteoarthritis, or OA, may affect not only how dogs function but how they feel and act too. Osteoarthritis, or OA, is a progressive condition that occurs when the cartilage protecting the bones gradually deteriorates, or breaks down over time.

RIMADYL is the most trusted OA pain medicine that helps get dogs back to their playful, lovable selves.

Early, lasting pain relief can lead to happier, more active dogs.1

No one knows your dog better than you. Spotting the early signs of OA can help you get your dog’s pain treated as soon as possible. Talk to your veterinarian about an OA screening and how treatment with RIMADYL can make a big difference.

RIMADYL (pronounced “Rim-a-dill”) is a nonsteroidal anti-inflammatory drug (NSAID) approved for once- or twice-daily dosing to relieve the pain and inflammation in the joints of dogs with OA. It comes in easy-to-use caplets and tasty chewables. After just 2 weeks of taking RIMADYL at label dose, dogs had visible improvements in energy, happiness, activity level, comfort, and calmness.1

  • OA may affect about 37% of dogs, according to a recent US study based on screening 504 dogs2
  • OA does not just come with old age–it affects dogs of all ages, sizes, and breeds2,3 OA can affect any dog, even as young as 1 year old…from Chihuahua to Mastiff.
  • The pain of OA can impact your dog’s emotional health too. Less common signs of pain in dogs include faster heart rate, reduced appetite, depression, and reluctance to move4

The home advantage can go a long way.

That’s why experts say it’s important to monitor your dog’s behavior and how they move around to help your veterinary team best manage your dog's OA pain.1,5

A history of trusted pain relief.

  • The most trusted NSAID prescribed by veterinarians6
  • More than 3 billion doses dispensed7
  • Over 26 million dogs treated8
  • Over 22 years of research

RIMADYL is a choice backed by confidence. It was the first FDA‑approved NSAID for dogs and has been used more than all other canine NSAIDs combined!

RIMADYL is also the top NSAID used during canine orthopedic surgeries and for continuous pain relief after surgery.

New data shows how RIMADYL helps keep dogs happy and active.

Continuous daily treatment with RIMADYL at label dose has been shown to significantly improve dogs’ functional ability and emotional well-being. To see how it improves both mobility and quality of life, view the recent study data below.

A new study involving 133 dogs with OA confirms that taking RIMADYL at label dose made it easier for dogs to do the activities they loved most.2

  • Dogs improved performance in all 5 daily activities tested*2
  • Dogs continually improved in stair climbing throughout 4 months on RIMADYL2
  • After just 1 month on RIMADYL, dogs had a much easier time getting up after lying down2

*Walking on a leash, jogging on a leash, getting up from sitting or lying down, walking upstairs, and walking downstairs

In the first study to report the impact of continuous NSAID treatment beyond 120 days in dogs with OA, taking RIMADYL at label dose provided rapid and ongoing improvements in both physical and emotional well-being.1

  • After just 2 weeks on RIMADYL, dogs showed visible improvements in energy, happiness, activity level, comfort, and calmness1
  • Dogs maintained quality of life improvements over 8 months of treatment
  • In the 1st clinical trial of its kind, RIMADYL had noticeable improvements in pain-related psychological measures1
RIMADYL dogs are happy dogs - and the data confirms it.

You’re friends with your dog for the long term…

How you help your dog’s OA pain over time can make all the difference.

RIMADYL is such an effective treatment, you may see improvements in your dog’s joint pain in as little as 2 weeks. You might think it’s OK to stop when you see your dog is feeling better. But OA is a painful, progressive disease, so it’s important to stick with the prescribed course. Your dog’s pain can worsen if you stop treatment earlier than prescribed.9

Long-term treatment provides continuous improvement in your dog’s OA pain and mobility, so your dog can stay involved in the activities you love to do together. Studies show that continuous use of NSAIDs—in particular RIMADYL—over the long term has been found to be safe.1,2

OA treatment requires a comprehensive approach.

If properly treated, the progression of OA can be slowed. The goals of OA treatment are to decrease pain and inflammation, resulting in:

  • Increased activity
  • Preserved muscle mass and strength
  • Regained function
  • Improved emotional well-being1

Medical treatment of arthritis should include weight control, exercise, and NSAIDs for an improved quality of life.

We’ve used RIMADYL before and it gave our dogs several years of quality life. Our dog Shotoku, a lovely golden retriever, lived until 15, definitely thanks to RIMADYL. Sho’s first indication of arthritis was that he could no longer catch his beloved balls and Frisbee without pain – we gave him RIMADYL and he was almost a puppy again. Very much an improvement over our first golden, Nezzer, who was before RIMADYL was available and was in quite a lot of pain the last 3-4 years of his life. Churchill, an English Setter, lived to be 14, and our 10.5 year-old English Setter, Diamond, just started RIMADYL. We expect Di, like Church and Sho, to live a happier life these next few years! When/if the time comes, we won't hesitate to put our cocker, Mandy, now 7, on it as well.

My Whippet, Haley, has had chronic neck issues her entire life. Then last year, when she was 13, the situation came to a head. We tried all types of treatments including laser therapy and acupuncture, but nothing provided relief. It got to the point where Haley was having mini-seizures from the pain. The specialist almost guaranteed me that after surgery Haley would be pain free. As I started weaning Haley off of the medications, the symptoms started coming back. I could see her guarding her neck like she did before the surgery. So, after a washout period, I started Haley on RIMADYL and I began to see a marked improvement almost right away. It was difficult and painful to give Haley pills to swallow. Now I just put the RIMADYL tablet in my hand and Haley takes it right away.

Frequently Asked Questions

Have questions? We’re here to help.

Osteoarthritis, or OA, is a painful condition caused by “wear and tear” of cartilage and other parts of the joints that may result in physical and emotional changes or signs in your dog, including:

  • Limping or lameness
  • Decreased activity or exercise (trouble standing, climbing stairs, jumping, or running)
  • Stiffness or decreased movement of joints
  • Sadness
  • A drop in energy level

The sooner OA is diagnosed, the better your dog’s pain can be managed. A good way to start is to complete this easy OA Checklist.

RIMADYL is a nonsteroidal anti-inflammatory drug, or NSAID, that’s used to reduce pain and inflammation (soreness) due to osteoarthritis and surgery in dogs. A licensed veterinarian must prescribe RIMADYL for your dog. It’s available as a caplet and chewable tablet and is given to dogs by mouth.

RIMADYL is backed by many years of successful use and is, in fact, the most trusted NSAID prescribed by veterinarians.5

RIMADYL works by blocking the production of certain body chemicals that cause inflammation. Its efficacy in treating OA makes it a trusted long-term treatment, as well as for short-term use after surgery. The nonsteroidal anti-inflammatory properties work to reduce joint inflammation while the analgesic properties work to reduce pain.

RIMADYL can relieve the pain and inflammation of OA and improve your dog’s mobility. Response varies from dog to dog but can be quite dramatic. In most dogs, improvement can be seen in a matter of days.

If RIMADYL is stopped or not given as directed, your dog’s pain and inflammation may come back since OA is a progressive condition. But continuous daily treatment with RIMADYL at label dose has been proven to significantly improve dogs’ functional ability and emotional well-being.2 See how.

Your veterinarian will need to assess your dog’s health and medication history to get to the source of the pain, and you play an important role since you know your dog best. If it turns out to be OA, the goals of treatment are to decrease pain and inflammation. This should involve weight control, exercise, and NSAIDs. See how you can partner with your veterinary team to best manage your dog’s OA pain.

While OA is progressive, a comprehensive treatment plan can manage your dog’s pain and help keep your furry friend active and playful. Learn how long-term treatment with RIMADYL can provide continuous improvement in your dog’s OA pain and mobility.

Important Safety Information: As a class, NSAIDS may be associated with gastrointestinal, kidney and liver side effects. These are usually mild, but may be serious. Pet owners should discontinue therapy and contact their veterinarian immediately if side effects occur. Evaluation for pre-existing conditions and regular monitoring are recommended for pets on any medication, including RIMADYL. Use with other NSAIDS or corticosteroids should be avoided.
