How to eliminate pubic lice? - briefly
Apply an FDA‑approved pediculicide lotion or shampoo (e.g., permethrin 1% or pyrethrin) to the affected area, follow the label‑specified contact time, then rinse and repeat the treatment after 7–10 days while washing all clothing, bedding, and towels at high temperature or sealing them for two weeks. If the infestation does not clear, seek a prescription medication such as ivermectin and consult a healthcare professional.
How to eliminate pubic lice? - in detail
Pubic lice, also known as crabs, require prompt and thorough eradication to prevent reinfestation and secondary skin irritation. The following protocol addresses medication, hygiene measures, and follow‑up care.
Medication is the primary intervention. Over‑the‑counter topical insecticides containing 1 % permethrin or 0.5 % pyrethrin with piperonyl butoxide are applied to the affected area for ten minutes, then washed off. Prescription options include a single dose of oral ivermectin (200 µg/kg) or a prescription lotion of 0.5 % malathion, both of which remain effective for several days after application. Repeat the chosen treatment after 7–10 days to eliminate newly hatched nits.
Hygiene practices support the chemical treatment. Immediately after application:
- Wash all clothing, bedding, and towels in hot water (≥ 60 °C) and dry on high heat.
- Seal non‑washable items in a sealed plastic bag for two weeks.
- Shower with warm water and mild soap, avoiding harsh scrubbing that could damage skin.
Personal contacts should be advised to undergo the same regimen simultaneously, as transmission occurs through close skin‑to‑skin contact. Sexual partners must be treated even if asymptomatic.
Post‑treatment assessment involves inspecting the pubic region 24 hours after the second application. Look for live insects, live nits, or persistent itching. If any remain, repeat the treatment cycle or consult a healthcare professional for alternative agents such as benzyl benzoate or spinosad.
Preventive measures include:
- Maintaining short or shaved pubic hair to reduce habitat.
- Using condoms or barrier methods during sexual activity.
- Avoiding sharing personal items that contact the genital area.
Adhering to the outlined steps eliminates the infestation, alleviates symptoms, and reduces the likelihood of recurrence.
