What is the best product to treat finger fungus?

The best products for treating nail fungus include Sporanox and Lamisil, according to Mayo Clinic. Both of these treatments are oral antifungal drugs that help users to grow new, healthy nails that slowly replace infected ones.

Treatment with oral antifungal drugs takes up to 12 weeks, notes Mayo Clinic. The end result is not readily visible, and it can take up to four months for the treated nails to regrow and the infection to be eliminated. Success with treatment declines in people over the age of 65, but results may be improved by combining both topical antifungal and oral antifungal products.
