What can a pregnant person use to treat the head for lice? - in detail
A pregnant individual who discovers head lice should choose treatments with proven safety for the fetus. The first‑line option is a 1 % permethrin shampoo or lotion, applied to dry hair, left for 10 minutes, then rinsed. Permethrin is classified as Category C but extensive use in pregnancy has shown no adverse outcomes, making it the preferred over‑the‑counter pediculicide.
If permethrin is unavailable or ineffective, a combination of pyrethrins with piperonyl‑butoxide can be used. The product must be applied exactly as directed, avoiding prolonged scalp contact. This formulation also carries a Category C rating, with clinical data supporting its safety in pregnancy.
Prescription‑only agents should be limited. Benzyl‑alcohol 5 % lotion is approved for use in pregnant patients; it kills lice without neurotoxic effects. Malathion and spinosad are not recommended because of insufficient safety data.
Mechanical removal is a reliable adjunct. Wet‑combing with a fine‑toothed nit comb, performed on damp hair after applying a conditioner, eliminates live lice and nits. Repeating the combing session every 2–3 days for two weeks ensures complete eradication.
Supportive measures include:
- Washing bedding, hats, scarves, and brushes in hot water (≥ 130 °F) and drying on high heat.
- Sealing non‑washable items in a sealed bag for two weeks.
- Avoiding hair‑spray insecticides, essential oils, or home‑made remedies lacking safety studies.
Before initiating any treatment, a healthcare professional should confirm the diagnosis and review the patient’s medical history. Continuous monitoring for skin irritation or allergic reaction is essential; discontinue the product and seek medical advice if adverse effects appear.
