What should be applied to marks from bedbug bites? - in detail
Effective management of skin reactions caused by cimicid insects involves several steps.
Initial care focuses on reducing irritation and preventing infection. Gently cleanse the affected area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can exacerbate inflammation.
Topical agents provide symptomatic relief. Apply a thin layer of a low‑potency corticosteroid cream (e.g., hydrocortisone 1 %) two to three times daily to diminish erythema and pruritus. For patients preferring non‑steroidal options, calamine lotion or a 1 % pramoxine gel can be used similarly.
Systemic antihistamines alleviate itching and reduce the histamine response. Oral diphenhydramine (25–50 mg) or cetirizine (10 mg) taken once daily are appropriate choices; dosage adjustments may be required for children or individuals with hepatic impairment.
Cold therapy offers immediate soothing effects. Apply a clean, cold compress or an ice pack wrapped in cloth for 10–15 minutes, repeating every hour as needed.
If secondary bacterial infection is suspected—evidenced by increasing warmth, swelling, pus, or fever—initiate a topical antibiotic such as mupirocin 2 % or seek medical evaluation for systemic therapy.
Persistent or severe reactions warrant professional assessment. Dermatologic consultation is advisable when lesions persist beyond two weeks, when ulceration occurs, or when allergic hypersensitivity is suspected.
In summary, comprehensive care includes cleansing, topical corticosteroids or alternative soothing agents, oral antihistamines, cold compresses, and vigilant monitoring for infection, with escalation to medical treatment when indicated.
