Treatment for toenail fungal infection can be through oral and topical medications, according to Mayo Clinic. For severe cases, surgical procedure or laser therapy may be needed.
Doctor-prescribed oral medications, such as terbinafine and itraconazole, effectively treat fungal infections by boosting new nail growth, gradually replacing the infected portion. It may take more than four months to totally eliminate the infection, says Mayo Clinic. Medicated anti-fungal nail polish or cream may also be prescribed by the doctor. Alternative methods include the application of snakeroot extract or tea tree oil on the infected part. Nail removal is a surgical procedure implemented on severe and painful cases of nail infection. Laser and light-based therapies also help in the elimination of severe infection.
