Clinical pearls
- First-line for mild distal subungual onychomycosis affecting <2 nails or <50% nail surface (BAD Guideline).
- For severe disease (matrix involvement, ≥3 nails, immunocompromised), oral terbinafine is more effective — combine with topical amorolfine for adjunctive benefit.
- Treatment is long (9–12 months for toenails); counsel about adherence and slow visible response — wait for healthy nail growth.
- Curanail 5% available OTC in UK pharmacy.
- Confirm diagnosis with nail clipping for mycology before starting — many dystrophic nails are not fungal.
