Terbinafine is an antifungal agent that treats fungus on the skin, hair and nails. It inhibits the synthesis of ergosterol which is an important component of the fungal cell membrane, hence leading to the death of the fungus. Terbinafine is used for the treatment of nail fungus (onychomycosis) and athlete’s foot (tinea pedis), as well as other fungal skin infections.
Terbinafine can be either taken in conventional tablets or applied in cream, spray or gel. If you are taking Terbinafine orally, it is important to check your liver and renal function with your doctor before initiating therapy. It will take several weeks to see the full effect of oral Terbinafine. It is important to apply sunscreen and avoid tanning beds while taking oral Terbinafine, as sensitivity to the sun is a side effect.
