How to get rid of lice on a doctor's recommendation? - briefly
A physician will prescribe a medicated pediculicide, such as 1 % permethrin shampoo, to be applied to the scalp for the recommended duration and repeated after 7–10 days. Simultaneously, wash all bedding, clothing, and personal items in hot water and vacuum the home to eliminate any remaining nits.
How to get rid of lice on a doctor's recommendation? - in detail
When a physician advises treatment for head‑lice, the plan typically follows a sequence of evidence‑based actions.
First, obtain a precise diagnosis. The doctor will examine the scalp and hair for live nits attached within 1 cm of the hair shaft and for active insects. Confirmation allows selection of the most appropriate medication.
Second, apply a prescription pediculicide. Common options include:
- 1% permethrin lotion, left on the scalp for 10 minutes before rinsing.
- 0.5% malathion spray, applied to dry hair and left for 8–12 hours.
- Spinosad 0.9% lotion, left for 10 minutes then washed out.
The doctor will specify dosage, repeat interval (usually 7–10 days), and any contraindications (e.g., age, pregnancy, skin conditions).
Third, complement chemical treatment with mechanical removal. Use a fine‑toothed nit comb on wet, conditioned hair, working from scalp outward. Perform combing at least twice daily for a week, discarding comb teeth after each use.
Fourth, treat the environment to prevent re‑infestation:
- Wash bedding, hats, scarves, and hair accessories 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 and upholstered furniture; discard vacuum bags promptly.
Fifth, schedule a follow‑up visit. The physician will reassess the scalp after the second treatment cycle to verify eradication and to address any adverse reactions.
Finally, educate the patient and household members about transmission routes—direct head contact and sharing personal items—to reduce future risk.
