How is a bed bug bite treated? - in detail
Bed‑bug sting lesions usually present as red, itchy papules that may develop into small vesicles. Immediate care begins with thorough cleansing; wash the affected area with mild soap and lukewarm water to remove any residual debris and reduce bacterial load. Apply a cool compress for 10–15 minutes, repeating every hour, to lessen swelling and discomfort.
Topical agents are the next line of defense. Over‑the‑counter hydrocortisone cream (1 %) can be spread thinly on the bite to suppress inflammation and alleviate pruritus. For more intense irritation, a prescription‑strength corticosteroid ointment may be applied according to a physician’s guidance. Antihistamine tablets such as diphenhydramine or cetirizine help control systemic itching and reduce histamine‑mediated swelling; dosage follows standard adult recommendations unless contraindicated.
If the skin becomes broken or shows signs of infection—pus, increasing redness, warmth, or fever—seek medical evaluation. Oral antibiotics (e.g., cephalexin or clindamycin) may be prescribed based on culture results or empirical guidelines. Keep the area covered with a sterile dressing to protect against further contamination.
Avoid scratching, as mechanical irritation can exacerbate inflammation and introduce pathogens. For persistent or widespread reactions, a short course of oral corticosteroids may be considered under professional supervision.
Monitoring is essential. Document changes in size, color, and symptom intensity over 24–48 hours. Should the reaction worsen or systemic symptoms such as headache, dizziness, or shortness of breath appear, immediate medical attention is required.
Finally, remove the source of infestation to prevent recurrent bites. Professional pest control, thorough laundering of bedding at 60 °C, and vacuuming of mattresses and furniture are critical components of long‑term management.
