How can you treat bedbug bites on a person? - in detail
Treating bites from Cimex lectularius requires a systematic approach to reduce itching, prevent infection, and promote skin healing. Begin by cleansing each lesion with mild soap and lukewarm water; this removes irritants and lowers bacterial load. Pat the area dry with a clean towel, avoiding vigorous rubbing that could exacerbate inflammation.
Apply a topical antihistamine or corticosteroid cream. Over‑the‑counter hydrocortisone (1 %) or a non‑sedating antihistamine ointment provides rapid relief of pruritus and reduces erythema. For extensive reactions, a short course of oral antihistamines such as cetirizine or diphenhydramine can be added, following dosage instructions on the label.
If lesions develop welts or vesicles, cover them with sterile gauze to protect against scratching and secondary infection. Should signs of infection appear—purulent discharge, increasing warmth, or spreading redness—seek medical evaluation promptly. A physician may prescribe oral antibiotics and a stronger steroid preparation.
Adjunctive measures enhance comfort. Cool compresses applied for 10–15 minutes, several times daily, lessen swelling. Calamine lotion or a 1 % zinc oxide paste can soothe irritated skin. Avoid heat sources, tight clothing, and harsh chemicals that may aggravate the rash.
For individuals with heightened sensitivity or allergic reactions, a brief course of systemic corticosteroids may be indicated under professional supervision. Documentation of the bite pattern and any systemic symptoms (fever, malaise) assists clinicians in assessing severity.
Finally, monitor the affected areas for several days. Most bites resolve within one to two weeks without scarring. Persistent hyperpigmentation or chronic itching warrants dermatological consultation to evaluate for post‑inflammatory changes or other dermatoses.
