What should be bought at a pharmacy to treat lice? - briefly
Buy an over‑the‑counter pediculicide such as 1 % permethrin or pyrethrin lotion, a dimethicone‑based spray, and a fine‑tooth nit comb for nits removal. Additional options include malathion, benzyl‑alcohol or ivermectin preparations if resistance is a concern.
What should be bought at a pharmacy to treat lice? - in detail
When lice infestations are confirmed, the pharmacy supplies several categories of products that address the problem effectively.
First‑line treatments are topical pediculicides. These contain insecticidal agents such as permethrin (1 %) or pyrethrins combined with piperonyl‑butoxide. Apply the lotion or shampoo to dry hair, leave it on for the recommended time (usually 10 minutes), then rinse thoroughly. Follow the label’s schedule for a second application 7–10 days later to kill newly hatched nymphs.
If resistance to permethrin is suspected, alternative agents include:
- Malathion 0.5 % – oil‑based solution applied to damp hair, left for 8–12 hours before washing.
- Benzyl alcohol 5 % – non‑insecticidal suffocation method, applied for 10 minutes, then rinsed; repeat after 7 days.
- Ivermectin 0.5 % lotion – applied once for 10 minutes; a second dose may be recommended after a week.
Adjunctive items aid in comprehensive management:
- Fine‑toothed nit combs – metal or plastic combs designed to remove eggs (nits) from hair shafts. Use after each treatment session and continue daily for at least two weeks.
- Hair conditioners – applied before combing to reduce friction and facilitate nit removal.
- Protective covers – pillowcase and mattress encasements to prevent re‑infestation from bedding.
- Disinfectant sprays – for cleaning combs, brushes, hats, and other personal items that may harbor lice.
For household decontamination, purchase:
- Laundry detergent – wash clothing, bed linens, and towels in hot water (≥ 130 °F/54 °C) and tumble dry on high heat.
- Vacuum cleaner – to remove stray hairs and debris from carpets and upholstery.
In cases of severe irritation or allergic reaction, a pharmacist may recommend a short course of oral antihistamines or a mild corticosteroid cream, but these should be used only under medical guidance.
Finally, retain the original packaging and instructions for each product. Verify expiration dates and store items in a cool, dry place to maintain efficacy.
