Adults and children: Treatment should be initiated as soon as possible after the start of the infection, ideally during the prodromal period or when lesions first appear.
A thin film of cream should be applied to the infected area and immediately adjacent skin areas 5 times daily at 4-hour intervals during the day.
Treatment should be continued for 5 days, followed by a further 5 days treatment if healing has not occurred.
Patients should wash their hands before and after applying the cream and avoid unnecessary rubbing of the lesions or touching with a towel, to avoid aggravating or transferring the infection.
