How to treat a skin mite? - briefly
Effective management includes applying topical scabicidal agents such as permethrin 5% or benzyl benzoate, and, for extensive infestations, administering a single oral dose of ivermectin (200 µg/kg).
How to treat a skin mite? - in detail
Treating a skin‑mite infestation requires a systematic approach that combines pharmacologic therapy, hygiene measures, and environmental control.
The first step is accurate diagnosis. Clinical examination reveals intense itching, erythema, and often a characteristic burrow or papule. Microscopic skin scrapings confirm the presence of the mite.
Pharmacologic options fall into two categories:
-
Topical agents
- Permethrin 5 % cream applied to the entire body from neck down, left on for 8–14 hours, then washed off. Repeat after 7 days.
- Benzyl benzoate 25 % lotion, applied similarly, with a second application after one week.
- Crotamiton 10 % cream, applied nightly for three consecutive nights.
-
Systemic medications
- Ivermectin 200 µg/kg orally as a single dose, repeated after 7 days for severe cases.
- Albendazole 400 mg daily for three days may be used when ivermectin is contraindicated.
Adjunctive measures enhance effectiveness:
- Bathing – Warm water shower before applying topical treatments removes excess oil and debris, allowing better drug penetration.
- Clothing and linens – Wash all garments, bedding, and towels in hot water (≥60 °C) and tumble‑dry on high heat. Items that cannot be laundered should be sealed in plastic bags for at least 72 hours.
- Environmental cleaning – Vacuum carpets, upholstery, and mattresses; discard vacuum bags immediately.
- Personal hygiene – Trim fingernails to reduce secondary skin injury; avoid scratching to prevent bacterial superinfection.
Monitoring progress is essential. Re‑examine the skin after 7–10 days; residual lesions may persist despite mite eradication, but pruritus should diminish markedly. If symptoms continue, repeat the treatment cycle or consider combination therapy.
Prevention focuses on avoiding re‑infestation:
- Maintain regular laundering of bedding and clothing.
- Use a mild, non‑oil‑based moisturizer to keep skin barrier intact, reducing susceptibility.
- Educate household members about the transmission route and encourage prompt treatment of any new cases.
Following this protocol—accurate identification, appropriate medication, strict hygiene, and vigilant follow‑up—provides reliable resolution of a skin‑mite problem.
