you need to take those perscription toenail fungus pills cuz usually the topical agents can't reach the fungus ...

also please be careful not to contaminate your other toes (or fingernails) by the affected toe ... because toenail fungus can spread ....

I agree with the above poster in that topical agents usually do not work. However, toenail fungus can also be the physical manifestation of an internal fungal/bacterial imbalance. In the past, I have found success with taking a combination of probiotics and herbal supplements that fight candida (the specific supplement I used was called Candidastat, I believe). These are supplements that you can probably find at any Whole Foods or natural health stores. The nice thing w/ those supplements was that I didn't have to deal with any harsh side effects.
