My cat has CKD. Will she need lifelong injections? Any side effects?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 14 years and 2 months old

Hi. First of all I want to thank you for replying my questions. My cat has CKD and swollen kidneys. My vet prescribed to give her Dexamethasone+Dimedrol+Vitamin C injections for 15 days. If one day I stop the injection she feels bad and stops eating, drinking. Water starts coming from her mouth. My question is will I have to keep her on this injection all life? And Can this medicine affect my cat badly if used for a longer period of time?

Unfortunately kidney disease in an older cat is generally a progressive disease. The treatments you are giving Mesi now are probably helping her feel better but the disease process is still continuing. Her kidneys will continue to shut down over time. I would recommend continuing the treatments for now if it is helping her feel better, eat, etc. You can also try to space out the treatments (like giving them every other day) instead of daily and see if that is still beneficial for Mesi. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
