Many of the pediculicides used for head louse infestation are also used for pubic louse infestation. In addition, P pubis infestations of the eyelashes are treated with occlusive therapies.

Pubic lice can be treated with over-the-counter permethrin 1% lotion and a mousse containing pyrethrins and piperonyl butoxide (RID foam). [13] Although malathion lotion 0.5% has been used to treat pubic lice, it is currently not FDA approved to treat pubic lice. Lindane shampoo causes neurotoxicity and should not be used as a first-line agent; it should be reserved for cases of resistance or when other medications are not tolerated. [13]
