My vet suggested cream for cat ringworm, but it's not working. Help!

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 4 months and 21 days old | 3 lbs

My vet recommended only OTC cream (Lotrimin AF) to treat my cats ringworm. He said he could prescribe oral anti-fungal (ITRAFUNGOL ORAL SOLUTION) if I wanted but that it is expensive. He also said I could do lime sulfur dips but they aren't that important. I have just been using the cream for a week and her spots are worse. Is this cream harmful (it's for people)? I want to ask for the oral medicine and go ahead an do the Lime Sulfur Dips ASAP. Is my vet not taking this seriously?

The cream isn't harmful but I have never come across a topical medication that has been effective for treating ringworm in cats aside from prescription-based lime sulfur dips. The concern is that the Microsporum canis (fungal organism causing ringworm) is spread diffusely throughout a cat's entire hair coat, such that an isolated topical spray will not cover all surfaces of every hair, and lead to frequent recurrence. Since the topical treatment isn't working and Nova's spots are worse, I would go back to the vet to get an oral treatment. I hope that all goes well!
