What to do for itching from a bedbug bite? - in detail
The itch that follows a bed‑bug bite can be managed with a systematic approach. Begin by cleaning the area with mild soap and lukewarm water; this removes irritants and reduces the risk of secondary infection. Pat the skin dry, then apply a cold compress for 10–15 minutes to constrict blood vessels and lessen swelling.
Topical options include over‑the‑counter corticosteroid creams (1% hydrocortisone) applied two to three times daily, or antihistamine ointments containing diphenhydramine. For those who prefer non‑pharmaceutical measures, calamine lotion, aloe vera gel, or a thin layer of pure honey can provide soothing effects and create a barrier against further irritation.
If the reaction is more pronounced, oral antihistamines such as cetirizine, loratadine, or diphenhydramine may be taken according to package directions. These agents block histamine release, decreasing redness and pruritus. In cases of extensive swelling, pain, or signs of infection (pus, increasing warmth, fever), consult a healthcare professional promptly; prescription‑strength steroids or antibiotics might be required.
Avoid scratching, as mechanical trauma can exacerbate inflammation and introduce bacteria. Keep fingernails trimmed and consider wearing cotton gloves during sleep if the urge to scratch is strong. Moisturizing the skin after each treatment session helps maintain barrier integrity and prevents dry, cracked areas that attract further irritation.
Finally, address the source of the bites. Conduct a thorough inspection of bedding, mattress seams, and furniture for live insects or shed exoskeletons. Wash all linens in hot water (≥60 °C) and dry on high heat; vacuum carpets and upholstered surfaces, discarding the vacuum bag afterward. If infestation persists, enlist professional pest‑control services to eradicate the problem and eliminate future episodes of itching.
