What should be applied to mosquito and flea bites? - in detail
For relief of mosquito and flea bites, apply a layered approach that addresses inflammation, itching, and potential infection.
First, reduce swelling and redness. Use a topical corticosteroid such as 1 % hydrocortisone cream. Apply a thin layer to the affected area two to three times daily for up to seven days. For individuals who cannot tolerate steroids, a non‑steroidal anti‑inflammatory gel containing diclofenac or ketoprofen provides comparable edema control.
Second, alleviate pruritus. Antihistamine preparations—either oral diphenhydramine (25 mg) or topical dimethindene—interrupt histamine‑mediated nerve signaling. Apply the topical agent once every four hours; oral dosing should not exceed 300 mg per day.
Third, protect against secondary bacterial invasion. A broad‑spectrum antiseptic such as 2 % chlorhexidine solution or a bacitracin‑zinc ointment can be applied after cleansing the skin with mild soap and lukewarm water. Allow the skin to dry before covering with a sterile, non‑adhesive dressing if the bite is exposed to friction.
Additional measures enhance comfort:
- Cool compresses (5–10 °C) for 10 minutes, repeated every hour during the first 24 hours.
- Calamine lotion or a 1 % menthol preparation for a cooling effect.
- Avoid scratching; use a silicone finger guard if necessary.
If symptoms persist beyond 72 hours, intensify inflammation, or signs of infection appear (purulent discharge, increasing warmth, fever), seek medical evaluation for possible systemic antibiotics or stronger prescription steroids.
