What to do if an adult is bitten by fleas? - in detail
When an adult experiences flea bites, immediate and systematic care reduces discomfort and prevents complications.
First, cleanse the affected area. Wash the skin with mild soap and lukewarm water for at least 30 seconds. Pat dry with a clean towel; avoid rubbing, which can aggravate irritation.
Second, apply a topical anti‑itch or anti‑inflammatory agent. Options include:
- 1 % hydrocortisone cream, applied thinly three times daily.
- Calamine lotion or a menthol‑based gel for soothing relief.
- Antihistamine cream (e.g., diphenhydramine) if itching is severe.
Third, consider oral antihistamines for systemic relief, especially when multiple bites cause widespread itching. Typical doses are:
- Diphenhydramine 25‑50 mg every 6 hours, not exceeding 300 mg per day.
- Cetirizine 10 mg once daily, if non‑sedating action is desired.
Fourth, monitor for signs of infection or allergic reaction. Seek medical attention if any of the following appear:
- Redness spreading beyond the bite site.
- Warmth, swelling, or pus formation.
- Fever, chills, or generalized rash.
- Difficulty breathing or swelling of lips/tongue.
Fifth, eradicate the source to prevent re‑exposure. Steps include:
- Vacuum carpets, rugs, and upholstery thoroughly; discard the vacuum bag or clean the canister afterward.
- Wash bedding, clothing, and pet blankets in hot water (≥ 60 °C) and dry on high heat.
- Treat pets with a veterinarian‑recommended flea control product; repeat according to the product’s schedule.
- Apply an environmental flea spray or fogger to infested indoor areas, following label instructions.
Lastly, support skin healing. Keep the area moisturized with a fragrance‑free lotion, avoid tight clothing, and refrain from scratching to minimize secondary infection.
By following these actions promptly, discomfort subsides, the risk of complications diminishes, and future bites are less likely.
