How to treat louse bites? - in detail
Lice bites produce itchy, red papules that may become inflamed or infected. Immediate relief focuses on reducing itching, preventing secondary infection, and promoting skin healing.
First‑line measures involve cleansing the affected area with mild soap and lukewarm water. Pat the skin dry, then apply a topical antihistamine or corticosteroid cream to calm the inflammatory response. Over‑the‑counter options such as 1 % hydrocortisone or a 0.5 % diphenhydramine lotion are effective when used according to package directions.
If itching persists, oral antihistamines (e.g., cetirizine 10 mg once daily) can be added. Non‑steroidal anti‑inflammatory drugs (ibuprofen 200–400 mg every 6 hours) may alleviate discomfort and reduce swelling.
When lesions show signs of bacterial involvement—pus, increasing warmth, or expanding redness—apply a topical antibiotic (e.g., mupirocin 2 % ointment) and consider a short course of oral antibiotics prescribed by a clinician.
Adjunctive care includes:
- Cool compresses for 10–15 minutes, several times daily, to lessen itching.
- Calamine lotion or zinc oxide paste to create a protective barrier.
- Avoid scratching; keep nails trimmed to minimize skin trauma.
- Use clean, breathable clothing; wash linens and clothing in hot water (≥60 °C) and dry on high heat to eradicate residual lice and eggs.
Persistent or worsening symptoms, extensive rash, or systemic signs such as fever warrant medical evaluation. A healthcare professional may perform a skin swab to identify bacterial pathogens and recommend prescription‑strength treatments.
Long‑term management requires eliminating the source of infestation. Treat all individuals in the household with an approved pediculicide shampoo or lotion, following the manufacturer’s protocol for repeat application. Vacuum carpets, upholstered furniture, and bedding; seal non‑washable items in plastic bags for two weeks to interrupt the life cycle.
By combining symptomatic relief, infection control, and eradication of the underlying lice population, the discomfort associated with bites can be resolved efficiently and recurrence prevented.
