How to cure pubic lice? - briefly
Use an OTC pediculicide such as 1 % permethrin or a pyrethrin‑based shampoo, applying it to the genital region, leaving it for the recommended duration, then washing off and repeating the treatment after 7–10 days. Wash all clothing, bedding, and towels in hot water or discard them to prevent reinfestation.
How to cure pubic lice? - in detail
Treating pubic lice requires a combination of medication, thorough cleaning of personal items, and preventive measures to avoid reinfestation.
First‑line therapy consists of a topical insecticide applied to the affected area. Options include:
- 1 % permethrin cream or lotion, applied to the genital region and surrounding hair, left on for 10 minutes, then rinsed off.
- Pyrethrins combined with piperonyl‑butoxide, used in the same manner as permethrin.
If resistance or intolerance is suspected, a prescription product may be employed:
- 0.5 % malathion lotion, applied for 8–12 hours before washing.
- Oral ivermectin, a single dose of 200 µg/kg; a second dose is often given one week later.
Application guidelines:
- Clean the area with mild soap and dry thoroughly.
- Apply the medication to the entire hair‑bearing region, not just visible nits.
- Follow the exact exposure time indicated on the product label; over‑exposure can cause skin irritation.
- Rinse with warm water and pat dry.
- Repeat the treatment after 7–10 days to eliminate newly hatched lice.
Environmental decontamination is essential:
- Wash all clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat.
- Items that cannot be laundered should be sealed in a plastic bag for at least two weeks.
- Vacuum carpets and upholstered furniture to remove stray nits.
Sexual partners must receive simultaneous treatment, even if asymptomatic, to prevent cross‑infection. Abstain from sexual activity until both parties have completed the full treatment regimen and all visible lice and nits are cleared.
Follow‑up:
- Examine the treated area after the second application. Absence of live lice confirms success.
- Persistent itching or visible nits after two weeks warrants medical review for possible secondary infection or alternative therapy.
Prompt, complete treatment combined with proper hygiene eliminates the infestation and reduces the risk of recurrence.
