Which ointments are used to treat subcutaneous ticks? - briefly
Topical preparations such as «permethrin» 5 % cream, «ivermectin» lotion, and low‑strength «hydrocortisone» ointment are used to eradicate embedded ticks and alleviate local irritation. Application follows product directions and is confined to the affected skin area.
Which ointments are used to treat subcutaneous ticks? - in detail
Topical agents applied after removal of an embedded tick aim to reduce inflammation, prevent secondary infection, and alleviate local discomfort. The most frequently recommended preparations include:
-
Corticosteroid ointments (e.g., hydrocortisone 1 % or betamethasone valerate).
Reduce erythema and pruritus; apply thinly to the affected area two to three times daily for up to five days. -
Antiparasitic creams (e.g., permethrin 5 % lotion, ivermectin 1 % cream).
Provide residual activity against any remaining larval stages; apply once, following manufacturer instructions, and avoid occlusion. -
Broad‑spectrum antibiotic ointments (e.g., mupirocin 2 %, bacitracin‑neomycin).
Protect against bacterial colonisation, especially when the skin shows signs of abrasion; apply two to three times daily for 7–10 days. -
Antiseptic gels (e.g., povidone‑iodine 10 % solution, chlorhexidine ointment).
Offer immediate reduction of microbial load; a single application after cleaning is sufficient, with repeat if contamination persists. -
Local anesthetic preparations (e.g., lidocaine 2.5 % with prilocaine 2.5 %).
Provide short‑term pain relief; apply once, allowing up to two hours of numbness before re‑application if needed. -
Wound‑healing agents (e.g., hyaluronic acid ointment, silicone gel).
Support tissue regeneration in cases of extensive dermal trauma; apply once daily until the lesion resolves.
Selection of a specific ointment depends on the clinical presentation. In the absence of infection, a low‑potency corticosteroid combined with a mild antiseptic often suffices. When signs of bacterial involvement appear—purulent discharge, increasing warmth, or expanding erythema—an antibiotic ointment should be added. Persistent itching or allergic reaction may warrant a higher‑strength corticosteroid or a topical antihistamine. Systemic therapy (oral doxycycline, for example) remains outside the scope of topical treatment but may be indicated if Lyme disease or other tick‑borne infections are suspected.
