You raise an interesting question though and I'm going to post a new thread in Cat Health asking why people who have cats with healthy immune systems treat ringworm since the medication can damage the liver, and have other side effects.
You are right, with the FIV+ kitties I would be more concerned with the outbreak having more of an affect on them! My vet told me about the liver and kidney risks with the medication, so I opted to try local treatment and thankfully that was all I needed!
