How should lice be poisoned in a child? - briefly
Apply an FDA‑approved topical pediculicide (e.g., 1 % permethrin shampoo) to dry hair, leave for the specified duration, then rinse and repeat the treatment after 7–10 days to eradicate newly hatched nits. Follow with a fine‑tooth nit comb to remove dead insects and eggs, and launder bedding and clothing in hot water.
How should lice be poisoned in a child? - in detail
Treating head‑lice infestation in a child requires a systematic approach that combines chemical treatment, mechanical removal, and environmental control.
Select an FDA‑approved pediculicide formulated for pediatric use. Permethrin 1 % lotion, pyrethrin with piperonyl‑butoxide, or dimethicone‑based products are the most widely documented. Verify the age recommendation on the label; most formulations are safe for children aged two months and older, while some require a minimum age of six months.
Apply the product according to the manufacturer’s instructions:
- Part hair into manageable sections.
- Apply the lotion or spray to dry scalp, ensuring coverage from the hair roots to the tips.
- Leave the preparation on the scalp for the specified contact time (usually 10 – 15 minutes).
- Rinse thoroughly with lukewarm water; avoid hot water, which can irritate the skin.
After the initial treatment, repeat the application after 7–10 days to eliminate newly hatched nymphs that survived the first dose.
Mechanical removal enhances efficacy:
- Use a fine‑toothed nit comb on wet, conditioned hair.
- Comb from scalp to tip in systematic passes, cleaning the comb after each stroke.
- Perform combing sessions daily for three consecutive days following each chemical treatment.
Environmental measures reduce re‑infestation risk:
- Wash bedding, hats, scarves, and clothing worn within the previous 48 hours in hot water (≥ 60 °C) and tumble‑dry on high heat.
- Seal non‑washable items in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags or clean canisters promptly.
Monitor the child for adverse reactions. Common side effects include mild scalp irritation, redness, or itching. Discontinue use and seek medical advice if severe rash, swelling, or respiratory symptoms develop.
For children with known sensitivities to neurotoxic insecticides, prefer dimethicone, which works by physically coating and suffocating lice without chemical toxicity.
Document each treatment session, noting product used, date, and any observed side effects. This record helps healthcare providers assess progress and adjust the regimen if necessary.
If infestation persists after two full treatment cycles, refer to a pediatrician for alternative therapies, such as oral ivermectin (off‑label use) or prescription‑strength pediculicides.
Adhering strictly to the dosage, timing, and follow‑up protocol maximizes eradication while minimizing risk to the child’s health.
