What should be applied to skin bitten by fleas? - in detail
Flea bites cause localized inflammation, itching, and occasional swelling. Effective topical management focuses on reducing histamine response, soothing the skin, and preventing secondary infection.
Antihistamine preparations such as diphenhydramine cream or oral cetirizine lower itching by blocking histamine receptors. Apply a thin layer of diphenhydramine 1 % cream to the affected area up to three times daily; oral antihistamines may be taken according to the dosage instructions on the package.
Corticosteroid ointments, for example hydrocortisone 1 % or betamethasone 0.05 %, suppress inflammatory mediators. Use a small amount on the bite site two to three times per day for no more than seven days to avoid skin thinning.
Soothing agents provide additional comfort:
- Calamine lotion – dries exudate and offers a cooling effect. Apply liberally after cleansing, repeat as needed.
- Aloe vera gel – delivers moisture and anti‑inflammatory compounds. Apply a thin film several times daily.
- Witch‑hazel extract – astringent that reduces edema. Pat gently onto the skin with a cotton pad.
If the bite becomes ulcerated or shows signs of infection (increased redness, warmth, pus), a topical antibiotic such as mupirocin 2 % should be applied after cleaning the area with mild soap and water.
General care measures:
- Wash the bite with lukewarm water and mild cleanser to remove irritants.
- Pat dry; avoid rubbing, which can aggravate the lesion.
- Keep nails trimmed to limit self‑inflicted trauma from scratching.
- Use a non‑permeable barrier (e.g., a breathable bandage) if the area is likely to be disturbed.
For individuals with severe reactions, systemic corticosteroids may be prescribed by a healthcare professional. In all cases, monitor the skin for changes; seek medical attention if symptoms persist beyond a few days or worsen rapidly.
