What to apply to bedbug bites? - in detail
Bedbug bite reactions can be eased with a range of topical and systemic agents.
Topical options
- Hydrocortisone 1 % cream: reduces inflammation and itching when applied 2–3 times daily for up to 7 days.
- Calamine lotion: creates a cooling film that soothes mild irritation; reapply as needed.
- Antihistamine ointments (e.g., diphenhydramine 1 %): block histamine release, diminishing pruritus.
- Aloe vera gel: provides moisture and mild anti‑inflammatory effects; apply fresh gel 3–4 times a day.
- Tea tree oil (5 % dilution in carrier oil): offers antiseptic and anti‑inflammatory properties; test on a small skin area before use.
- Baking soda paste (mix equal parts baking soda and water): neutralizes acidic skin secretions; apply for 10 minutes, then rinse.
Systemic treatments
- Oral antihistamines such as cetirizine 10 mg or diphenhydramine 25–50 mg: lessen widespread itching, especially when multiple bites are present.
- Non‑steroidal anti‑inflammatory drugs (ibuprofen 200–400 mg): alleviate pain and swelling if severe.
Supportive measures
- Cold compress (wrapped ice pack) for 5–10 minutes: constricts blood vessels, decreasing swelling and numbness.
- Keep nails trimmed and skin clean to prevent secondary infection; wash the area with mild soap and lukewarm water twice daily.
- Avoid scratching; use a bandage or protective glove if necessary.
When medical attention is required
- Signs of infection: increasing redness, warmth, pus, or fever.
- Persistent swelling, blistering, or spreading rash despite treatment.
- Allergic reactions: hives, difficulty breathing, or swelling of lips and face.
A combination of a corticosteroid cream and an oral antihistamine provides the most rapid relief for moderate to severe itch. For mild reactions, calamine or aloe vera may suffice. Always follow dosage instructions and discontinue any product that causes irritation.
