What is the most effective product to treat toe nail fungus?

Nail Fungus: There is nothing that is 100% effective other than permanent removal of nail. I have found a combination of laser treatment and oral to be most successful.

Oral antifungal a: Oral antifungal a such as terbinafine also known as Lamisil or itraconazole known as sporonox. A 3-4 month course. Follow this up with antifungal powder into shoes q week to try to prevent reoccurrence.

We can try!: Toenail fungus is very common, and unfortunately very difficult to cure 100%. We can test the nail to see if it's a callused or traumatized nail or if it's fungus, and from there you have several options: topical (~30% effective) or oral (~70%) antifungal medications, laser nail treatment (80%), or removal of the nail in severe cases. See your doctor to talk about which treatment is right for you.
