How to relieve itching after a lice bite? - in detail
Lice bites trigger a localized allergic reaction that manifests as intense skin irritation. The sensation arises from saliva proteins injected during feeding, which provoke histamine release. Prompt relief requires a combination of pharmacological and non‑pharmacological interventions.
First‑line measures focus on reducing inflammation and soothing the skin. Apply a cold compress for 5–10 minutes, repeating every hour as needed. Over‑the‑counter antihistamine tablets (e.g., cetirizine, loratadine) taken at the recommended dosage diminish histamine activity and lessen itching. Topical corticosteroid creams (hydrocortisone 1 %) applied thinly to the affected area three times daily provide rapid anti‑inflammatory effects.
Adjunctive home remedies can complement medical treatment. A dilute solution of witch hazel (1 % – 2 %) applied with a cotton pad reduces erythema. Calamine lotion creates a cooling barrier that interferes with nerve signals. A paste made from baking soda and water, left on the bite for 10 minutes, neutralizes skin acidity and alleviates pruritus. For individuals with sensitive skin, a thin layer of pure aloe vera gel offers moisture and anti‑inflammatory properties.
When symptoms persist beyond 48 hours, or if secondary infection signs appear (increased warmth, pus, spreading redness), seek professional evaluation. Prescription-strength corticosteroids or oral antihistamines may be required. In rare cases, a physician may recommend a short course of antibiotics if bacterial colonization is confirmed.
Preventive actions reduce future occurrences. Regularly wash bedding, clothing, and personal items in hot water (≥ 60 °C). Use a fine‑toothed comb on damp hair to remove lice and nits. Apply a preventive lice treatment containing permethrin or dimethicone as directed by health guidelines.
Combining immediate symptom control, supportive home care, and diligent prevention provides comprehensive relief from the discomfort associated with lice bites.
