How to treat scabies caused by ticks? - briefly
Apply a topical 5 % permethrin cream to the affected skin, leave it on for 8–12 hours, then wash it off; repeat the treatment after 7 days to ensure eradication. If extensive or refractory, administer a single oral dose of ivermectin (200 µg/kg) and consider a second dose after 1–2 weeks.
How to treat scabies caused by ticks? - in detail
Treating a tick‑related infestation that mimics scabies requires a systematic approach: confirm the diagnosis, apply appropriate pharmacotherapy, implement strict hygiene, and monitor response.
First, obtain a definitive diagnosis. Examine skin lesions for the characteristic burrows, papules, and intense nocturnal itching. Perform skin scrapings and microscopic analysis to identify mite bodies or eggs. In cases where tick exposure is documented, differentiate between true scabies and secondary dermatitis caused by tick saliva, as management may vary.
Pharmacological options include:
- Topical permethrin 5 % – apply to the entire body from neck down, leave for 8–14 hours, then wash off. Repeat after 7 days to eliminate newly hatched mites.
- Topical benzyl benzoate 25 % – apply similarly; useful where permethrin resistance is suspected.
- Oral ivermectin – dose 200 µg/kg body weight, repeat after 7 days. Consider for extensive disease, crusted forms, or when topical agents are contraindicated.
- Adjunctive antihistamines – reduce pruritus, improve sleep, and limit scratching that could lead to secondary infection.
Hygiene measures are essential to prevent reinfestation:
- Wash all bedding, clothing, and towels in hot water (≥ 60 °C) and dry on high heat.
- Vacuum carpets and upholstered furniture; discard vacuum bags promptly.
- Isolate untreated household members for at least 48 hours after the first treatment of the index case.
If secondary bacterial infection develops, prescribe an appropriate antibiotic based on culture results or local resistance patterns. Monitor patients weekly for reduction in lesions and itching. Persistent symptoms after two treatment cycles warrant re‑evaluation for drug resistance, alternative diagnoses, or immunocompromised status.
Education of patients and close contacts about avoiding further tick exposure, using repellents, and performing regular skin checks completes the management plan.
