How should one treat a bed bug bite? - in detail
A bed‑bug bite typically appears as a small, red, raised spot that may itch or become swollen. Immediate care focuses on reducing inflammation, preventing infection, and alleviating discomfort.
First, cleanse the area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can aggravate the skin. Apply a cold compress for 10–15 minutes to diminish swelling and soothe itching. Repeat every hour as needed during the first day.
If itching persists, use an over‑the‑counter antihistamine (e.g., diphenhydramine) or a topical corticosteroid cream (e.g., 1 % hydrocortisone). Follow the product’s dosage instructions; do not exceed the recommended frequency. For severe itch, a short course of oral antihistamines (e.g., cetirizine 10 mg) may be appropriate.
When a bite shows signs of infection—such as increasing redness, warmth, pus, or escalating pain—seek medical attention promptly. A healthcare professional may prescribe antibiotics or a stronger steroid formulation.
Additional measures:
- Keep fingernails trimmed to minimize skin damage from scratching.
- Wear loose‑fitting clothing to reduce friction on the bite site.
- Wash any clothing or bedding that contacted the bite in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes to eliminate any lingering insects or eggs.
- Apply a barrier ointment (e.g., petroleum jelly) if the skin is cracked, to protect against secondary infection.
For individuals with sensitive skin or allergies, perform a patch test with any topical medication before full application. Document the bite’s progression; photographs can aid clinicians in diagnosing complications.
Long‑term management includes eliminating the source of infestation. Professional pest control, thorough vacuuming of mattresses and seams, and encasing mattresses in zippered covers are essential steps to prevent further bites.
