What's the most suggested treatment for a fungal nail infection?

Depends: On your overall health and preference. There is no guarantee for cure but if healthy, oral medication or laser seem to have the best results. However, topical medication and proper care will probably always be needed to minimize recurrence anf repeated treatmemts in future may be necessary.

Varies : But the oral meds i.E Lamisil (terbinafine) is still the most effective documented treatment.

Oral Lamasil: Oral meds work well. We use laser in our practice.

Have them evaluated.: There are different topical and oral antifungal medications available for the treatment of nail fungus. Specialized lasers are also now available for treatment of fungal nail infections. Have your nails evaluated and get the appropriate treatment.
