What should be done if lice bite? - in detail
When a person experiences bites from head lice, immediate care focuses on relieving discomfort and preventing secondary infection. First, cleanse the affected area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can exacerbate irritation.
Apply a topical antiseptic or a mild corticosteroid cream to reduce inflammation and protect against bacterial invasion. Choose products containing hydrocortisone 1% or an over‑the‑counter antibiotic ointment, following the manufacturer’s instructions for frequency and duration.
To alleviate itching, an oral antihistamine such as diphenhydramine or loratadine can be taken, respecting dosage guidelines for age and weight. Non‑pharmacologic options include cool compresses applied for several minutes, repeated as needed.
Simultaneously, eradicate the lice infestation to stop further bites. Use a pediculicide shampoo or lotion approved by health authorities, applying it to damp hair and leaving it on for the recommended period before rinsing. After treatment, comb the hair with a fine‑toothed nit comb, removing dead insects and nits. Repeat combing every 2–3 days for at least two weeks.
Environmental decontamination reduces re‑infestation risk. Wash bedding, clothing, and personal items in hot water (minimum 130 °F/54 °C) and dry on high heat. Items unable to withstand heat should be sealed in airtight bags for two weeks. Vacuum carpets and upholstered furniture, discarding the vacuum bag or cleaning the canister afterward.
Monitor the scalp daily for signs of worsening redness, swelling, or pus formation. If any of these appear, seek medical evaluation promptly, as prescription antibiotics or stronger anti‑inflammatory agents may be required. Persistent itching despite treatment also warrants professional assessment to rule out allergic reactions or secondary skin conditions.
