What should I do for swelling from bedbug bites? - in detail
Treat the localized inflammation promptly. Begin by washing the affected area with mild soap and lukewarm water to remove any residual irritants. Pat the skin dry; do not rub, which could aggravate the reaction.
Apply a cold compress or an ice pack wrapped in a cloth for 10‑15 minutes. Repeat every hour for the first few hours to reduce edema and relieve discomfort.
If the swelling persists, consider oral antihistamines such as diphenhydramine or cetirizine, following the dosage instructions on the package. For more intense inflammation, a low‑potency topical corticosteroid—hydrocortisone 1 % cream—can be applied two to three times daily. Limit use to the recommended duration to avoid skin thinning.
Avoid scratching or picking at the lesions. Mechanical irritation can introduce bacteria, leading to secondary infection. Should signs of infection appear—red streaks, pus, increasing pain, or fever—consult a healthcare professional promptly.
In cases where swelling spreads beyond the bite site, or systemic symptoms such as difficulty breathing develop, seek emergency medical attention without delay.
Prevent future episodes by inspecting bedding, sealing cracks in furniture, and laundering linens at high temperatures. Vacuuming regularly and using encasements designed for bed‑bug control can further reduce exposure.
