What to apply to louse bites? - in detail
Lice bites cause itching, redness, and occasional swelling. Immediate relief comes from topical agents that calm inflammation and prevent infection.
Apply a corticosteroid cream (hydrocortisone 1 % or a stronger prescription formula) to reduce swelling and itching. Use a thin layer two to three times daily for up to a week, unless irritation develops.
Antihistamine ointments containing diphenhydramine or calamine lotion provide additional itch suppression. Apply after washing the affected area and reapply every four hours as needed.
If the skin appears broken or there is risk of bacterial invasion, a topical antibiotic such as mupirocin or bacitracin should be spread thinly over the lesion. Limit use to three days unless directed by a clinician.
For individuals seeking non‑medicated options, a cool compress applied for five minutes several times a day eases discomfort. Aloe vera gel, pure honey, or a diluted tea tree oil solution (one part oil to ten parts carrier) can soothe and possess mild antimicrobial properties; test on a small skin patch first to rule out sensitivity.
Oral antihistamines (e.g., cetirizine 10 mg once daily) are useful for severe pruritus that does not respond to topical treatment.
Maintain hygiene by washing clothes, bedding, and personal items in hot water (≥ 60 °C) and vacuuming upholstered surfaces. Re‑treating with a pediculicide shampoo eliminates the source of bites and prevents recurrence.
Monitor the bites for signs of infection—increased pain, pus, or spreading redness—and seek medical evaluation if these appear.
