What to do if lice bites itch? - in detail
Lice bites cause a localized, often intense itching that can become uncomfortable if left untreated. Immediate care focuses on cleaning the affected area, reducing inflammation, and preventing secondary infection.
First, wash the skin with mild soap and lukewarm water. Pat dry with a clean towel; rubbing may aggravate the irritation. Apply a cold compress for several minutes to constrict blood vessels and lessen the urge to scratch.
Next, treat the itch with one or more of the following options:
- Over‑the‑counter hydrocortisone cream (1 %) applied thinly to the bite, up to three times daily.
- Antihistamine tablets (e.g., cetirizine 10 mg) taken as directed to block histamine release.
- Calamine lotion or a zinc‑oxide paste for a soothing barrier.
- Topical anesthetics containing pramoxine or lidocaine for short‑term numbness.
If a natural approach is preferred, consider these alternatives:
- Diluted apple‑cider vinegar swabbed onto the bite; the mild acidity can reduce itching.
- Aloe vera gel applied directly; it supplies anti‑inflammatory compounds and moisture.
- A paste of baking soda and water left on the skin for 10 minutes; the alkalinity may neutralize irritants.
Avoid scratching, as it can break the skin and introduce bacteria. Keep fingernails trimmed and consider wearing cotton gloves at night if the urge is strong.
Maintain hygiene to stop further bites. Wash all bedding, clothing, and personal items in hot water (≥ 60 °C) and dry on high heat. Use a fine‑toothed comb on damp hair to remove any remaining lice or nits. Vacuum carpets and upholstered furniture to eliminate fallen debris.
Monitor the reaction for signs of infection: increasing redness, swelling, pus, or fever. If any of these develop, seek medical attention promptly. Persistent or worsening itching despite treatment also warrants professional evaluation, as prescription‑strength steroids or alternative therapies may be required.
