How to treat after a bed bug bite? - in detail
When a bed‑bug bite appears, begin by washing the area with mild soap and cool water. This removes irritants and reduces the risk of bacterial entry. Pat the skin dry, then apply a thin layer of an antiseptic solution such as povidone‑iodine or a diluted hydrogen peroxide mixture.
To alleviate itching, use a topical antihistamine cream containing diphenhydramine or a corticosteroid ointment with 1 % hydrocortisone. Apply only once or twice daily, following the product’s instructions. Oral antihistamines—loratadine, cetirizine, or diphenhydramine—provide systemic relief for more intense pruritus. Limit use of sedating agents before operating machinery.
If swelling persists, a non‑steroidal anti‑inflammatory drug (ibuprofen or naproxen) can reduce inflammation and discomfort. Dosage should match the label’s recommendations for adult use.
Monitor the bite for signs of infection: increasing redness, warmth, pus, or escalating pain. Should any of these appear, seek medical evaluation promptly. A clinician may prescribe a short course of oral antibiotics (e.g., cephalexin or doxycycline) and, if necessary, a stronger topical steroid.
For individuals with heightened sensitivity, a prescription‑strength corticosteroid cream (triamcinolone or betamethasone) may be required. In rare cases of severe allergic reaction—widespread hives, difficulty breathing, or rapid swelling—administer an epinephrine auto‑injector if available and call emergency services immediately.
Adjunctive measures that support skin recovery include:
- Keeping fingernails trimmed to prevent secondary trauma from scratching.
- Using cool compresses (a clean cloth soaked in cold water) for 10‑15 minutes, several times a day.
- Avoiding heat sources such as heating pads, which can exacerbate inflammation.
- Applying a thin layer of soothing aloe‑vera gel or a calamine lotion to maintain moisture and reduce irritation.
After the acute phase, protect the skin with a fragrance‑free moisturizer to prevent dryness and aid barrier repair. Continue to observe the area for at least one week, as delayed hypersensitivity reactions may emerge.
Finally, address the source of the bites. Conduct a thorough inspection of bedding, mattress seams, and furniture for live insects or shed exoskeletons. Wash all linens, clothing, and curtains in hot water (minimum 60 °C) and dry on high heat. Vacuum carpets and upholstered surfaces, sealing the vacuum bag immediately. Consider professional pest‑control treatment to eradicate the infestation and prevent recurrence.
