How can one treat bedbug bites? - in detail
Treating bites from Cimex lectularius requires a systematic approach to relieve symptoms, prevent infection, and reduce inflammation.
First, cleanse the affected area with mild soap and lukewarm water. Thorough washing removes residual saliva and reduces the risk of secondary bacterial invasion. Pat the skin dry with a clean towel; rubbing can exacerbate irritation.
Second, apply a cold compress for 10–15 minutes. The temperature drop constricts superficial blood vessels, diminishing swelling and itching. Repeat the application every few hours during the first day.
Third, address the histamine response. Oral antihistamines such as diphenhydramine (25 mg) or cetirizine (10 mg) taken every 12 hours alleviate pruritus and limit the wheal formation. For localized relief, over‑the‑counter topical antihistamine creams or calamine lotion can be spread thinly over each lesion.
Fourth, control inflammation with corticosteroid preparations. Low‑potency hydrocortisone 1 % cream applied twice daily for up to five days reduces erythema and edema. If lesions are extensive or unresponsive, a physician may prescribe a medium‑potency steroid (e.g., triamcinolone 0.1 %).
Fifth, prevent infection. If a bite appears broken or exudative, cover it with a sterile non‑adhesive dressing. Monitor for signs of bacterial involvement—rapidly expanding redness, warmth, pus, or fever. Seek medical evaluation promptly if any of these occur.
Sixth, avoid further trauma. Refrain from scratching, which can introduce pathogens and prolong healing. Trim fingernails short and consider wearing gloves at night if compulsive scratching is a problem.
Additional supportive measures include:
- Moisturizing the skin with fragrance‑free emollients to restore barrier function.
- Using oatmeal or baking‑soda paste (mix with water) as a soothing soak for widespread itching.
- Maintaining a cool, low‑humidity environment to reduce additional bites.
If symptoms persist beyond a week, worsen, or systemic reactions such as hives, swelling of the face, or difficulty breathing develop, emergency medical care is required. Prescription antihistamines, oral corticosteroids, or antibiotics may become necessary under professional supervision.
Finally, treat the infestation itself to halt new bites. Professional pest control, thorough laundering of bedding at ≥ 60 °C, and vacuuming of cracks and crevices are essential steps, though they fall outside the direct management of the lesions.
