How should a lice bite be treated? - in detail
Lice bites cause localized irritation, redness, and itching. Immediate care should focus on soothing the skin, preventing secondary infection, and eliminating the source of infestation.
- Clean the affected area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can worsen inflammation.
- Apply a topical antihistamine or corticosteroid cream to reduce pruritus and swelling. Use a thin layer two to three times daily for up to five days, unless irritation persists.
- If the skin shows signs of infection—pus, increased warmth, or expanding redness—apply a topical antibiotic ointment containing bacitracin or mupirocin. Seek medical evaluation if symptoms worsen.
- Use oral antihistamines (e.g., cetirizine or diphenhydramine) for severe itching, especially at night, to improve comfort and sleep quality.
Simultaneously address the lice population to prevent new bites. Wash all clothing, bedding, and towels in hot water (≥60 °C) and dry on high heat. Items that cannot be heated should be sealed in plastic bags for two weeks. Vacuum carpets and upholstered furniture thoroughly; discard vacuum bags afterward. For personal treatment, apply a pediculicide shampoo or lotion approved for head lice, following label instructions regarding exposure time and repeat dosing.
After initial relief, monitor the site for lingering redness or hyperpigmentation. If discoloration persists beyond two weeks, consider a mild bleaching agent (e.g., 2 % hydroquinone) or a prescription lightening cream, applied under dermatological supervision.
Overall management combines skin care, symptom control, infection prevention, and eradication of the parasite to achieve complete resolution.
