How can lice be removed in pregnant women? - in detail

Pregnant patients who discover a head‑lice infestation need a treatment plan that eliminates the parasites while avoiding substances that could affect fetal development. The first step is mechanical removal. A fine‑toothed nit comb, used on wet, conditioned hair, can extract live insects and eggs. Comb the scalp from the crown to the hair tips in sections, rinsing the comb after each pass. Repeating this process every 2–3 days for at least two weeks ensures that newly hatched nymphs are caught before they mature.

Topical products approved for use in pregnancy provide an additional layer of control. Permethrin 1 % lotion is classified as pregnancy‑category B; it is applied to dry hair, left for 10 minutes, then washed off. A second application after 7–10 days targets any surviving eggs. Benzyl‑alcohol lotion (5 %) is also considered safe, but it must be left on the scalp for at least 10 minutes before rinsing. Both agents should be used according to the manufacturer’s instructions and only after confirming tolerance.

Systemic medications are generally avoided. Oral ivermectin is contraindicated because of insufficient safety data for the fetus, and malathion is also discouraged due to potential toxicity. Herbal or essential‑oil preparations, such as tea‑tree oil, lack robust clinical evidence and may cause skin irritation; they should not replace proven treatments.

Environmental decontamination reduces the chance of re‑infestation. Wash all bedding, hats, scarves, and hair accessories in hot water (≥ 60 °C) and tumble‑dry on high heat. Items that cannot be laundered should be sealed in plastic bags for two weeks, the period required for lice to die without a host. Vacuum carpets and upholstered furniture, and avoid sharing combs, pillows, or hats.

Pregnant individuals should consult their obstetrician or dermatologist before initiating any lice regimen. The clinician can verify that the chosen product is appropriate for the gestational stage, assess for allergic reactions, and provide guidance on follow‑up examinations to confirm eradication. Regular scalp inspections for at least four weeks after treatment help ensure that the infestation has been fully resolved.
