Aporyl is a nail lacquer and belongs to a family of medicines called anti-fungals. These medicines work by killing a wide variety of fungi that can cause nail infections. Aporyl is used to treat fungal infections of the nails. Treatment with this nail lacquer alone is not suitable for use in severe infections where the lunula is affected. Because fungal nail infections are hard to treat, treatment may be required for 6-12 months or longer and a full cure cannot be expected in all cases.
