Kidney Toxicity (Drug-Induced) in Cats




Most cats with drug-induced nephrotoxicity will require inpatient care, especially those that are also suffering from kidney failure. In these severe cases, surgery may be required.


Living and Management


Once the cat has returned to your home, it is important that his activity be reduced and that you provide him with a modified diet that is not excessive in protein and phosphorous. Dehydration is a common threat for cats with kidney problems; you will need to monitor him for any untoward symptoms and advise your veterinarian if they should occur, who may assist by administering fluid therapy.


Electrolyte panels may be performed as frequently as every one or two days in order to evaluate the severity of azotemia, a condition commonly associated with drug-induced nephrotoxicity, in which abnormal levels of nitrogen-containing compounds (such as a number of body-waste compounds) are found in the blood. This is of utmost importance, as cats with severely progressed azotemia may develop acute kidney failure within days.


Moreover, drug-induced nephrotoxicity may even lead to chronic kidney disease months or years later. Therefore, if any signs of illness -- such as vomiting or diarrhea -- recur, contact your veterinarian immediately.




The best way to prevent this type of toxicity is to not use nephrotoxic drugs. However, if your cat requires this type of medication, administer it only under the advisement of your veterinarian. You should also consult him or her before adjusting the dosage and the possibility of adverse drug interactions.
