My kitten has coccidia. Metronidazole or wait for ponazuril?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 2 months and 27 days old | 8 lbs

My kittens are sick due to coccidia. I was given bactrim, but the next day one of my kittens was much worse. The vet thought it was a bad reaction to bactrim and prescribed metronidazole and we are waiting for ponazuril to be ready. The metronidazole wasn't ready until the next day and he seemed much better by then. The vet says to give the metro anyway, but I'm afraid of another bad reaction - even the probiotics I'm giving him seem to make him lethargic. should I just wait for the ponazuril?

If it were my kitty I would start the metronidazole right away. Metronidazole adverse reactions are not that common and it can at least help with the inflammation of the gut that is caused by the coccidia until the proper dewormer is made available. I hope that your kitty is able to make a full and speedy recovery. Best wishes and take care!
