Terbinafine works by interfering with the production of ergosterol, an essential component of fungal cell membranes.

• Damages the fungal cell membrane
• Prevents fungal growth and survival
• Leads to gradual clearance of the infection
• Effective against common dermatophyte fungi

For nail infections, visible improvement may take weeks to months as healthy nail grows back.
