|Purrs Cosmo. So sorry about the CCL. Please ask your mom to be cautious and ask your vet more questions about Metacam before using it. Only the injectable form of Metacam is approved for use on cats in the US, not the oral form, although that doesn't mean vets can't prescribe it and they do prescribe the oral form because it is helpful for pain relief for cats, but giving it orally has risks for cats that your mom should know about before giving it to you. Please read all of this article in the link and the other links:
Common uses of Metacam in Cats
Metacam is commonly used in cats for two cases: a) Metacam Solution for Injection (or simply "Metacam Injection") is used to provide post-operative relief of pain and inflammation for up to 24 hours following procedures such as dentistry, spaying and neutering. Vets often prescribe a few daily follow-up doses of Metacam Oral for continued pain relief, although this is not an FDA approved use.(b) Metacam Oral Suspension (or simply "Metacam Oral") is often prescribed to relieve arthritis pain in cats. Although this is also not an FDA approved use, it is known to be effective, albeit with some risk.
Low Safety Margin = Higher Risks
According to the manufacturer�s product sheet1, Metacam has a narrow margin of safety (also known as therapeutic index) in cats, meaning that there is very little difference between a safe, effective dose and a toxic dose. Repeated doses of Metacam Oral in cats have been known to result in death, as documented in the clinical tests3submitted to the FDA.The narrow safety margin in cats is reflected in the FDA�s Adverse Drug Experience (ADE) reports4for Metacam Oral, which summarize drug side effects reported by veterinarians. Of 842 reports for dogs, 19 cases of kidney failure and no deaths were reported. However in 320 cats, 105 cases of kidney failure, 48 deaths and 35 cases resulting in euthanasia have been reported. This clearly indicates that Metacam poses a much greater risk in cats than in dogs
