What should be applied for flea bites? - briefly

What should be applied for flea bites? - in detail

Flea bites cause itching, redness, and occasional swelling. Immediate care focuses on reducing inflammation, preventing infection, and soothing discomfort.

First‑line topical agents include:

  • Hydrocortisone 1 % cream – mild corticosteroid that diminishes erythema and pruritus. Apply a thin layer to the affected area two to three times daily for up to seven days.
  • Calamine lotion – astringent and antipruritic formulation that dries out lesions and provides a cooling effect. Use as needed, reapplying after washing.
  • Antihistamine creams (e.g., diphenhydramine) – block histamine receptors locally, decreasing itch intensity. Limit use to short periods to avoid skin irritation.

If the bite is inflamed or secondarily infected, a topical antibiotic may be warranted:

  • Mupirocin 2 % ointment – effective against Staphylococcus aureus and Streptococcus pyogenes. Apply after cleaning the site, twice daily, until signs of infection subside.
  • Neomycin‑polymyxin‑bacitracin (triple‑antibiotic) ointment – broad‑spectrum coverage for minor bacterial involvement. Use for a maximum of five days to limit resistance risk.

Adjunctive measures enhance recovery:

  • Cold compresses – reduce swelling and numb nerve endings; apply for 10–15 minutes, several times a day.
  • Oral antihistamines (e.g., cetirizine 10 mg) – control systemic itching when multiple bites are present; follow dosing instructions on the label.
  • Gentle cleansing – wash the area with mild soap and lukewarm water to remove irritants; pat dry before applying any medication.

Avoid scratching, as it can break the skin barrier and introduce pathogens. If lesions expand, develop pus, or persist beyond a week, seek professional medical evaluation.
