How to treat bites from lice? - in detail
Lice bites cause localized itching, redness, and sometimes a raised rash. The first step is to cleanse the affected skin with mild soap and lukewarm water, removing any irritants and reducing the risk of secondary infection. Pat the area dry with a clean towel; avoid rubbing, which can worsen irritation.
Topical options include:
- Over‑the‑counter hydrocortisone cream (1 %) applied two to three times daily for up to seven days to diminish inflammation.
- Antihistamine ointments or oral antihistamines such as cetirizine or diphenhydramine to relieve itching and prevent scratching.
- Calamine lotion or a zinc‑oxide paste for soothing dry, irritated skin.
If the reaction is severe, a prescription‑strength corticosteroid cream may be warranted; a healthcare professional should evaluate the need for such medication. Persistent swelling, pus formation, or signs of infection (fever, increasing pain) require prompt medical attention.
Adjunctive measures help control discomfort:
- Cool compresses applied for 10–15 minutes, several times a day, lower skin temperature and provide temporary relief.
- Keeping fingernails trimmed reduces the likelihood of skin damage from scratching.
- Wearing loose, breathable clothing minimizes friction and allows the skin to heal.
When multiple family members are affected, treat all individuals simultaneously and wash clothing, bedding, and towels in hot water (minimum 60 °C) followed by a high‑heat dryer cycle. Items that cannot be laundered should be sealed in plastic bags for two weeks to kill any remaining lice and their eggs.
Consult a medical provider if symptoms persist beyond a week, if allergic reactions develop (hives, difficulty breathing), or if underlying skin conditions complicate the presentation. Proper treatment and hygiene practices typically resolve the irritation within a few days.
