How to treat itching after a bedbug bite? - in detail
When a bedbug bite triggers an uncomfortable sensation, the first step is to stop the itch before the skin becomes irritated further. Clean the area with mild soap and lukewarm water; this removes potential allergens and reduces bacterial risk. Pat the skin dry, then apply a cold compress for 5–10 minutes to numb the nerve endings and lessen swelling.
For pharmacological relief, consider the following options:
- Topical antihistamines (e.g., 1% diphenhydramine cream) applied 2–3 times daily block histamine release, curbing redness and itching.
- Corticosteroid ointments (e.g., 1% hydrocortisone) reduce inflammation; limit use to 7 days to avoid skin thinning.
- Oral antihistamines (e.g., cetirizine 10 mg) taken once daily control systemic allergic responses, especially when multiple bites are present.
- Analgesic gels containing lidocaine or benzocaine provide temporary numbness; follow label instructions regarding frequency.
If medication is unavailable, home-based measures can supplement relief:
- Aloe vera gel—applied directly, it soothes and hydrates damaged tissue.
- Oatmeal paste—mix colloidal oatmeal with water, spread on the bite, and leave for 15 minutes; the mucilaginous compounds calm irritation.
- Calamine lotion—creates a protective barrier and eases the urge to scratch.
- Baking soda slurry—combine one teaspoon of baking soda with a few drops of water, apply for 10 minutes, then rinse; the alkaline solution neutralizes acidic components of the venom.
Avoid scratching, as mechanical trauma introduces bacteria and can lead to secondary infection. If signs of infection appear—such as increasing pain, pus, spreading redness, or fever—seek medical attention promptly. Persistent or worsening itch despite over‑the‑counter treatment may indicate an allergic reaction requiring prescription‑strength corticosteroids or a referral to a dermatologist.
Long‑term management includes eliminating the source of the bites. Inspect bedding, furniture, and cracks for signs of infestation; wash all linens at 60 °C, vacuum thoroughly, and consider professional pest control if the problem persists. Reducing exposure removes the trigger and prevents recurrent itching episodes.
