How to treat the consequences of a bed bug bite? - in detail
Bed‑bug bites often produce localized redness, swelling, and intense itching. Prompt cleaning with mild soap and lukewarm water reduces the risk of secondary infection. After washing, gently pat the area dry and apply a cold compress for 10–15 minutes to lessen inflammation.
Topical treatments can alleviate discomfort. Over‑the‑counter corticosteroid creams (hydrocortisone 1 %) or calamine lotion provide anti‑inflammatory and antipruritic effects. Antihistamine tablets such as diphenhydramine or cetirizine lessen systemic itching and reduce histamine‑mediated swelling. For persistent lesions, a short course of oral corticosteroids may be prescribed by a healthcare professional.
If the bite becomes infected, signs include increasing pain, pus, or fever. In such cases, a topical antibiotic (e.g., mupirocin) or oral antibiotics (e.g., cephalexin) should be administered according to medical advice. Maintaining proper wound hygiene—regular cleaning and avoiding scratching—prevents bacterial colonisation.
Allergic reactions may manifest as widespread hives, swelling of the lips or eyes, or difficulty breathing. Immediate administration of epinephrine auto‑injectors and urgent medical evaluation are required for anaphylactic responses.
Long‑term skin care supports recovery. Moisturising creams containing ceramides restore barrier function, while silicone gel sheets can minimise scar formation. Sun protection with broad‑spectrum SPF 30+ prevents hyperpigmentation in healing areas.
Key preventive measures include regular laundering of bedding at ≥ 60 °C, vacuuming mattresses and furniture, and encasing mattresses with zippered covers. Early detection of infestations—identifying rust‑colored spots, shed exoskeletons, or live insects—facilitates prompt eradication, reducing future bite occurrences.
