Dermatophyte (Fungal) Infection - Nail

Take nail clippings: start therapy only if infection is confirmed by laboratory.

Oral terbinafine is more effective than oral azole.

Idiosycratic liver reactions occur rarely with oral antifungals.

If candida or non-dermatophyte infection confirmed, use oral itraconazole.

For children, seek specialist advice.
