Has your veterinarian recommended the popular dog painkiller Rimadyl? Before giving it to your pup, you may want to learn more about this FDA-approved veterinary drug. What does Rimadyl do for dogs? What are the side effects? And is it safe?
I’ll answer these questions and more to help you make an informed decision with your vet about whether Rimadyl is the best option for your dog’s pain relief or if an alternative medication is a better choice.
What Is Rimadyl For Dogs?
Rimadyl is the most popular brand name for the prescription veterinary medication carprofen, which belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). What is Rimadyl used for in dogs?
- To control symptoms of osteoarthritis, including joint pain, inflammation, swelling, and stiffness
- To treat inflammation and pain in dogs, for example after surgery
- To reduce fever
Veterinary vs Human NSAIDs
Although you may have human NSAIDs in your medicine cabinets (ibuprofen, aspirin, naproxen, etc.), it’s important to use a vet-prescribed NSAID medication and dosage for your dog. Never give your dog a non-steroidal anti-inflammatory drug meant for humans.
How Much Rimadyl Can I Give My Dog?
Rimadyl comes in caplets, chewable tablets, and an injection. You can talk to your vet about the best form for your dog’s situation. The caplets and chewable tablets come in three strengths: 25mg, 75mg, and 100mg. The typical dosage is 2.0mg/lb once per day. However, the exact dose will depend on your specific dog and his condition. It’s crucial to stick to the dosage and frequency your vet prescribes.
Do I need a prescription for Rimadyl for dogs? Yes, your vet must prescribe it, and he or she will prescribe the ideal strength for your dog’s weight. Rimadyl dosage for dogs after surgery is the same as when being used to treat osteoarthritis pain.
