While living in the USA I also had toenail fungus and was prescribed Sporanax by a Podiatrist. This medication worked fantastic and now there is no trace of fungus even though my nail was quite deformed from the fungus it grew back perfect. This medication was very expensive approx. $250 for a months supply and was on it for approx. 3 months. It is also very harsh and I had to have numerous blood tests to check my liver while on it, but all in all it was worth it. There is also a very similar medication called Lamisil that does basically the same thing, again this is also very expensive but I've no idea how much it costs over here.
