Terbinafine 250mg/500mg is an antifungal medication used to treat a variety of fungal infections, particularly those affecting the skin and nails. It works by inhibiting the enzyme squalene epoxidase, which is essential for the synthesis of ergosterol, a key component of the fungal cell membrane. This disruption leads to the death of the fungus.

• 250mg is typically used for treating dermatophyte infections, such as athlete’s foot, ringworm, and nail infections.
• 500mg may be prescribed for more severe or widespread fungal infections or in cases where a higher dose is needed for effective treatment.

Terbinafine is available in oral and topical forms, with the oral formulation commonly used for more persistent or extensive fungal infections. It is generally well-tolerated, though some people may experience gastrointestinal disturbances, rash, or liver enzyme abnormalities.
