Pharmacology

Permethrin is a pyrethroid pediculocide and scabicide. It causes paralysis and death of the pest by inhibiting sodium ion influx through nerve cell membrane channels delaying repolarisation. Crotamiton has scabicidal and antipruritic action against Sarcoptes scabei. It is an effective pediculocide as well.

Interaction

The treatment of eczematous-like reactions with corticosteroids should be withheld prior to treatment with permethrin, as there is a risk of exacerbating the scabies infestation by reducing the immune response to the mite.
