Which is the correct treatment for Pediculosis pubis?

Permethrin cream is considered the first-line treatment for Pediculosis pubis, commonly known as pubic lice. This ectoparasitic infestation is effectively treated with this topical insecticide, which works by targeting the nervous system of the lice, leading to their death.

Permethrin is widely recognized for its efficacy against both lice and scabies, making it a suitable choice for the treatment of pubic lice. Its application typically involves spreading the cream over the affected area and surrounding regions, usually left on for a specified duration before being washed off.

In contrast, other options listed are not appropriate for this specific condition. Clotrimazole is an antifungal cream primarily used for fungal infections, making it ineffective against lice. Podofilox is used for treating genital warts, and selenium sulfide is primarily an antifungal treatment for seborrheic dermatitis and dandruff. As such, these alternatives do not have the necessary activity against pubic lice, reinforcing the choice of permethrin as the correct treatment.
