Ruling out oral meds, what are the best meds, OTC or prescription to treat nail fungus?

Nail fungus. Nothing really as effective as oral medicines, but perhaps pen-lac.
Several treatments. The reason you hear so many different treatments for toenail fungus is because there is no perfect, sure-fire treatment that works 100% of the time. I've seen vaporub work, as well as other natural oil remedies, but rarely. You can also try laser therapy, antifungal creams or nail paints if you can't take the oral medication. Talk to your doctor about which is right for you.
