PERMETHRIN
Formtopical
Permethrin 1% solution or rinse: apply to the affected area, leave on for 10 minutes, then wash off. The formulary carries this only as an adolescent, limited-data regimen — it gives no adult pubic-lice dose. - Single application; the formulary gives no repeat course for pubic lice
The formulary's only pubic-lice entry sits under paediatric dosing, for adolescents, and is flagged as limited data. Pubic lice in a pre-pubertal child is a safeguarding concern and needs assessment, not just treatment.

- The formulary records that the CDC considers permethrin one of the drugs of choice for pubic lice during pregnancy.
- For external use only. Avoid contact with the eyes and mucous membranes; do not apply inside the nose, ear, mouth or vagina.
- The 7-to-10-day repeat belongs to the head-lice regimen; the formulary gives no repeat for pubic lice.

- Treat all sexual partners from the last 3 months at the same time, or the patient is reinfected.
