Dogs suffer from cancer much like humans do. Cancer can affect their bones, skin and organs, while progressing slowly or rapidly. There are many different types of effective pain medications on the market today that help ease the pain of cancer complications. Your veterinarian will choose the most suitable pain medication to ensure your dog's comfort.

Non-Steroidal Anti-Inflammatory Drugs
-
Non-steroidal anti-inflammatory drugs are the most commonly prescribed pain medications. They include non-prescription drugs such as aspirin or prescription drugs such as deracoxib and tepoxalin. There is a low risk of side effects with these drugs, and they are used to treat mild to moderate pain. They are typically given orally, are well-absorbed then eliminated by the kidneys and liver. If your dog is in sudden pain, your veterinarian may administer them by injection for fast relief.
Steroids
-
Steroids are often prescribed for more serious cases of pain in dogs with cancer. Steroids act in the same way non-steroidal anti-inflammatory drugs work but are higher risk due to adverse side effects. Side effects include increased appetite, water consumption and urination, depression, weight gain, panting, diarrhea and hyperactivity. Steroid medications are commonly known by the names cortisone and prednisone. Steroids don't actually relieve pain, but they reduce inflammation causing the pain. Steroids are the most potent when it comes to anti-inflammatory medicines.
Opiods
-
Opiods are often prescribed for cancer-stricken dogs who are in severe pain. More commonly known by the names codeine and morphine, opiods are closely related to natural brain chemicals that limit sensitivity to pain. Opiods are highly addictive and have more adverse effects than non-steroidal anti-inflammatory drugs or steroids. These include slowed breathing and heart rate, physical dependency and constipation. Opiods are commonly used when all other forms of pain medication have failed but are rarely prescribed because of the possibility of illegal use by humans.
Anti-Depressants
-
Anti-depressants are prescribed for the long-term psychological effects of pain on dogs with cancer. According to Vet Info, when anti-depressants are used in combination with other pain medications, in almost all cases anti-depressants reduced the amount of other pain medications needed.
