  • Apply the medicated nail lacquer thinly to cover the whole of the affected nail(s) and surrounding skin using the brush provided. Apply the lacquer every 12 hours.
  • Leave the lacquer to dry for 10-15 minutes after application.
  • The lacquer does not dry hard.

    A transparent, slightly greasy film is left on the nail. This film contains the antifungal agent and it slowly passes through the nail to reach the site of infection.

  • The film should be left intact as long as possible. This allows the antifungal agent to have maximum effect.
  • Try to avoid putting your hands (or feet if your toenails are affected) in soapy water immediately after applying the solution. Soap or detergent removes the film. Water alone does not remove the film.
