See guidance on dosing in children for quick reference dosage/weight guide. Refer to drug interactions table for detailed drug interactions for all antimicrobials.

Comments from Expert Advisory Committee

  • In adults and children over 2 years of age permethrin dermal cream should be applied to the whole body excluding the head and paying particular attention to the areas between the fingers and toes, wrists, axillae, external genitalia, buttocks and under finger and toe nails.
  • In children between 2 months and 2 years permethrin dermal cream should be applied over the whole body as directed for adults and children over 2 years, but should include the face, neck, scalp and ears.
  • All members of the affected household should be treated simultaneously
  • For difficult to treat scabies, cases in assisted care facilities or immunocompromised hosts, seek dermatological advice.


Permethrin 5% or Malathion 0.5% lotion may be used, in lactating mothers, care must be taken that the breastfeeding infant does not suckle on treated skin thereby avoiding oral ingestion of the scabicide.

Ivermectin 200mcg/kg in adults 2 weeks apart has been shown to be effective in treating scabies, it is used in Europe and more recently in the U.K. But is not generally considered as a first line treatment. It is unsuitable for children in pregnancy or lactating mothers.
