Do you know the name of a tablet for fungal skin infection?

Yes, I do.: There are several; the most popular at the moment are terbinafine (trade name lamisil), ketoconazole (trade name nizoral), itraconazole (trade name sporanox), and Fluconazole (trade name diflucan). All have advantages and disadvantages, depending on the nature and location of the infection. An older medication called Griseofulvin is still used sometimes, but a lot of fungi are resistant to it now.
