How can i treat toenail fungus?

Several ways: Ranging from debridement, topical medication, oral medication, laser or removal of nail. Consult with podiatrist.

Few ways : Topical antifugals are less tan 10 % effective, oral medication is most effective, lasers are expensive and work about 70% of the time. You can do combinations of the above. If limited o 1-2 nails you can have the nail removed and then apply topical, or take oral and that would improve efficacy.

Oral Lamasil: I have found that the laser to be the most effective treatment.

Oral meds: Topical meds, lasers. Oral gives best treatment.
