My cat is drinking and peeing a lot. Is it a side effect of meds?

Updated on September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 9 months and 1 day old | 7.3 lbs

Clouseau is getting over a Upper respiratory infection and he got a shot of convenia on Monday and is on chlorpheniramine too. Additionally he's also on a course of itrafungol for ringworm. I've noticed that he's drinking a lot of water and urinating pretty frequently. Is this something to worry about or should I take him to the vet?

I'm not sure why this is happening, this is not a side effect usually seen with one of these medications so this could be due to a urinary condition. i would recommend to take him to the vet to get it checked, if it is a urinary infection the convenia should take care of it though.
