What can be applied after a bedbug bite? - in detail
After a bedbug bite, immediate skin care reduces irritation and prevents infection. Begin with gentle cleansing using lukewarm water and mild soap; pat dry without rubbing. Apply a cold compress for 10‑15 minutes to lessen swelling and numb itching.
Topical agents:
- Over‑the‑counter hydrocortisone 1% cream, applied 2‑3 times daily, controls inflammation.
- Antihistamine ointments containing diphenhydramine, applied to the affected area, relieve pruritus.
- Calamine lotion or zinc oxide paste forms a protective barrier and soothes redness.
- Topical anesthetics such as lidocaine 2.5% gel provide temporary pain relief.
Oral medications:
- Non‑prescription antihistamines (cetirizine, loratadine, diphenhydramine) taken according to package directions reduce systemic itching.
- Ibuprofen or acetaminophen, 200‑400 mg every 4‑6 hours, alleviate pain and fever if present.
If secondary infection is suspected—evidenced by increasing warmth, pus, or expanding redness—apply a topical antibiotic (e.g., bacitracin or mupirocin) and consider a short course of oral antibiotics prescribed by a clinician.
Additional measures:
- Keep fingernails trimmed to minimize skin damage from scratching.
- Use moisturizers after the acute phase to restore barrier function.
- Avoid tight clothing that may trap moisture and aggravate lesions.
Seek professional medical evaluation if symptoms persist beyond a few days, if severe allergic reactions occur (difficulty breathing, swelling of lips or face), or if the bite area rapidly worsens.
