Rimadyl is an anti-inflammatory (NSAID) that does not contain steroids, and is used to treat inflammation and pain as a result of arthritis and other joint disease, including hip dysplasia. Additionally, it is used to treat surgical pain and to reduce fever. A prescription from your veterianarian is required to purchase Rimadyl. Rimadyl is for dogs over six weeks of age. Rimadyl can be given as an effective, single daily dose, in either a chewable tablet or non-chewable caplet. Rimadyl is generally well tolerated by dogs. Rimadyl reduces the hormones that cause inflammation and pain in your dog's body. Be sure to contact your veterianarian or pharmacist and discuss giving any other prescription or over-the-counter medications to your pet while using Rimadyl. Rimadyl is not to be given to lactating or pregnant dogs, or dogs used for breeding.
