Painkillers for Dogs

Painkillers for Dogs

Rimadyl, Imadyl or Imafen are Carprofen based non-steroidal anti-inflammatory drugs used by veterinarians as a supportive treatment for the relief of arthritic symptoms in geriatric dogs. It can be used both short term, for joint pain or post-operative inflammation, or for day-to-day relief from the pain and inflammation associated with osteoarthritis, hip dysplasia, and other forms of joint deterioration.


Tramadol for animals is one of the most reliable and useful painkillers for dogs available to veterinarians for treating animals in pain. In animals, tramadol is removed from the body via liver and kidney excretion. Animals suffering from diseases in these systems should be monitored by a veterinarian, as it may be necessary to adjust the dose. Tramadol is normally used to control moderate to severe post-surgical pain, or as pain relief after injury as well as chronic pain in dogs suffering from cancer. Unlike Rimadyl, Tramadol is basically a narcotic-like pain reliever and not classified as NSAID drug.


Fentanyl is considered as one of the strongest painkillers for dogs. United States authorities classify fentanyl as a potent narcotic analgesic. To date, there are more than 12 different analogues of fentanyl have been produced clandestinely and identified in the U.S. drug traffic. Fentanyl for dogs is normally used in the form of skin patches which will release medication on a regular basis. Since it is classified as a strong narcotic analgesic, Fentanyl is recommended only for intensive unbearable pain, for example prior to surgery to control postoperative pain, and can be purchased through prescription only. In dogs, the Fentanyl effect can last up to 4 days but you should give 6 to 12 hours for the drugs to work effectively after the patch being applied. Please note that these patches are highly toxic and shouldn’t be ingested by the dog.


According to the manufacturer, Deramaxx is a breakthrough medication to help control chronic osteoarthritis (OA) pain in dogs and proven safe enough to use every day. Osteoarthritis is said to be the most common cause of chronic pain in dogs, and affects the dog’s joints. Deramaxx is classified as a non-narcotic, non-steroidal anti-inflammatory drug (NSAID). The active ingredient is deracoxib. Deramaxx is in the same pharmaceutical class as ibuprofen and aspirin.
