Terbinafine
"I have had toenail fungus for over 10 yrs. I have tried every over the counter medication and expensive drops. I had used Vinegar and Listerine, Vicks vapor rub and even two doses of the pin point laser, without any dramatic changes. I was getting so fed up. The laser doc, decided to give me a 3 month dosage of terbinafine. I am on my last week, and my toe nails have DRAMATICALLY gotten better. I just stare at them all of the time because I can't believe it.  In another two or three weeks they will be perfect. I have not had any side effects from the medication, although I will be having a liver check in a couple of weeks."
