Dealing with Adverse Reactions to Metacam

If you believe your cat has developed renal failure as a result of using Metacam, you should report this to the manufacturer. 

Most cats who suffer renal failure as a result of using Metacam are suffering from acute renal failure (ARF) and their bloodwork may be extremely high, with creatinine often in the high teens. Do not give up hope! Acute renal failure is difficult to treat, but not impossible: an aggressive treatment plan should see those numbers dramatically reduce in most cases, so don’t opt for euthanasia immediately.

A treatment program which includes 4-5 days of IV fluid therapy (hospitalisation), followed by 4-6 weeks of sub-Q fluids at home, is often recommended by the manufacturers, but talk to them and see what they suggest for your cat. I would also suggest that you ask the manufacturers to pay your veterinary costs – I know they have done this for some people, although they have not necessarily paid the full costs.

You should also make a report to the Food & Drug Administration. Apparently the manufacturers are not obliged to report any cases of renal failure to the FDA because renal failure is already listed in the package insert as a possible side effect (see the link below). But I believe it is very important for the FDA to be fully aware of the scale of the problem.
