Clean the affected area with mild soap and cool water, then apply a topical antihistamine or hydrocortisone cream to reduce itching and inflammation. If lesions worsen or show signs of infection, seek medical evaluation.
How to treat skin after bed bug bites? - in detail
Bed bug bites typically cause erythematous, pruritic papules that may develop into vesicles or wheals. Primary symptoms include localized itching, swelling, and occasional redness extending a few centimeters from the bite site.
Immediate care begins with gentle cleansing using mild soap and lukewarm water to remove irritants and reduce bacterial load. Applying a cold compress for 10–15 minutes limits vasodilation and alleviates itching. Over‑the‑counter antihistamine creams (e.g., diphenhydramine 1 %) provide topical relief; oral antihistamines (e.g., cetirizine 10 mg) further diminish systemic histamine response.
Pharmacological interventions for persistent inflammation encompass:
- Low‑potency topical corticosteroids (hydrocortisone 1 %) applied 2–3 times daily for up to 7 days.
- Mid‑potency corticosteroids (triamcinolone acetonide 0.1 %) for extensive or resistant lesions, limited to a 5‑day course.
- Non‑steroidal anti‑inflammatory drugs (ibuprofen 200 mg) taken every 6 hours for pain control, provided no contraindications exist.
Adjunctive home remedies support symptom reduction:
- Oatmeal paste (colloidal oatmeal mixed with water) applied for 20 minutes, then rinsed, soothes itching through barrier protection.
- Aloe vera gel (pure extract) offers anti‑inflammatory and cooling effects when applied twice daily.
- Baking soda slurry (1 part sodium bicarbonate to 3 parts water) reduces surface pH, diminishing irritation.
Preventing secondary infection requires maintaining short, clean fingernails, avoiding scratching, and monitoring for signs such as increased warmth, purulent discharge, or expanding erythema. Consultation with a healthcare professional is warranted if these indicators appear, or if lesions persist beyond 10 days despite treatment.
Long‑term skin management includes regular moisturization with fragrance‑free emollients to restore barrier function, and, when appropriate, gradual exposure to low‑dose antihistamines to reduce hypersensitivity. Persistent severe reactions may necessitate referral to a dermatologist for specialized therapy, including prescription‑strength corticosteroids or immunomodulators.
