Do the OTC treatments for athletes foot and toenail fungus work?

A friend of mine came to me with this question, because I tend to be “the doctor” and I have no idea how effetive the OTC treatments are for these things? I do know prescription Sporonox can work for severe cases of toe fungus, but I don’t think she is at that point, unless a Jelly suggests it is best to take a drug like that right off the bat.

Her toes barely look red, but she says they feel a little inflamed and seem a little swollen, and she does have discoloration on three toenails on the top third of the nails, so I think the diagnosis is right.

I can’t see any harm in trying OTC remedies first, which ones have you found best for curing the problem? She does not seem to be concerned with any discomfort, so please focus on a cure, and not just products that make it feel better.

Thanks!
