Metacam (meloxicam)

Meloxicam is only available by prescription, l. To treat postoperative pain in cats, a single dose of injectable meloxicam is approved by FDA. For severe conditions like cancer, an oral form of meloxicam is used off-label. But be aware kidney damage is likely to occur if Metacam is used for an extended period.

Opioids for cats

Opioids are a great alternative to NSAIDs for cats in pain by veterinarians. Sometimes, NSAIDs may not provide enough relief as needed for cats with moderate to severe pain, and in situations where NSAIDs are not a good option for a cat, Opioids are often prescribed.

There are two forms of Opioids, it could be natural( derived from the poppy plant) or synthetic( made in the lab). Either form of opioid binds to and also blocks receptors in the nervous system that play a role in pain sensation.

Opioids are substances that are very well controlled due to the potential for abuse and addiction in people.


This can be used for short-term pain relief, like after an injury or surgery, or even for more extended periods for other chronically painful conditions like cancer or osteoarthritis.

Buprenorphine can be absorbed through the mucous membranes in the mouth, or your vet could administer it through injections.

Tramadol can only be gotten through prescription, and it’s an effective short-term pain relief medication—especially after surgery. But it could be used for long periods for severe conditions like cancer.

Tramadol is usually compounded into liquids using cat-friendly flavors—because it is very bitter. Effects that could be noted in long-term use include lethargy, dilated pupils, strange behaviors, constipation, and seizures.

Duragesic (fentanyl patch)

After having an injury or surgery, cats may need several days of pain from moderate or severe pain—prescription fentanyl is administered chiefly.

Fentanyl patches are applied to the cat’s shaved skin—removed when the medication wares off(usually within five days). When used approximately, fentanyl patches are very safe for your cat. The aide effects could include dilated pupils, slow breathing, lethargy, vomiting, and high temperature.

Your vet can prescribe other types of cat-safe opioids.
