How do you defeat a scabies mite? - briefly
Treat the infestation with a scabicide such as 5 % permethrin cream applied to the entire body from the neck down for 8–14 hours and repeated after 7 days, or a single oral dose of ivermectin (200 µg/kg). Clean all clothing, linens and towels in hot water and dry on high heat to eliminate surviving mites.
How do you defeat a scabies mite? - in detail
To eradicate the organism responsible for scabies, a systematic approach is required. First‑line pharmacotherapy involves topical scabicidal agents applied to the entire body from the neck down, left on for the prescribed duration. Permethrin 5 % cream is the preferred option; it is applied overnight and washed off after 8–14 hours. Alternative topical preparations include benzyl benzoate and sulfur ointment, both requiring multiple applications at 24‑hour intervals.
Oral ivermectin provides an effective systemic option, particularly for crusted scabies or cases where topical treatment fails. The standard regimen consists of a single dose of 200 µg/kg, repeated after one week. For severe infestations, a second dose may be administered after an additional week.
Adjunctive measures reduce reinfestation risk. All household members and close contacts should receive simultaneous treatment, regardless of symptom presence. Bedding, clothing, and towels must be laundered in hot water (≥50 °C) and dried on high heat; items that cannot be washed should be sealed in plastic bags for at least 72 hours. Vacuuming carpets and upholstered furniture removes detached mites and eggs.
Symptom relief is achieved with antihistamines or low‑potency corticosteroid creams to control itching. Persistent pruritus after treatment may indicate a post‑scabetic reaction rather than ongoing infestation; in such cases, antihistamines or topical steroids remain appropriate.
A concise protocol:
- Apply 5 % permethrin cream to the entire body; leave for 8–14 hours; repeat after one week.
- If contraindicated or ineffective, administer oral ivermectin 200 µg/kg on day 0 and day 7; consider a third dose on day 14 for crusted cases.
- Treat all close contacts simultaneously with the same regimen.
- Wash or isolate all textiles and linens for ≥72 hours at ≥50 °C.
- Vacuum living areas thoroughly.
- Use antihistamines or topical steroids for itch control.
Following this regimen eliminates the parasite, prevents recurrence, and alleviates associated discomfort.
