What is the name of the ointment for subcutaneous ticks? - in detail
The ointment commonly employed to treat embedded ticks is a topical formulation of ivermectin, typically marketed as a 1 % cream.
Ivermectin acts by binding to glutamate‑gated chloride channels in the parasite’s nerve and muscle cells, causing hyperpolarization, paralysis, and death of the tick. The cream is applied directly to the affected skin area after the tick has been removed or when the bite is still present but the parasite is not visible.
Key characteristics of the preparation include:
- Concentration: 1 % ivermectin (10 mg/g).
- Application: thin layer over the bite site, once daily for 3–5 days, depending on the severity of local inflammation.
- Absorption: limited systemic uptake; the drug remains largely confined to the epidermis and superficial dermis.
- Indications: treatment of inflammatory reactions, secondary bacterial infection prevention, and eradication of residual tick tissue beneath the skin.
Safety profile:
- Common adverse effects: mild erythema, itching, or burning at the application site.
- Contraindications: known hypersensitivity to ivermectin or excipients, use in infants younger than 6 months, and patients with severe hepatic impairment.
- Drug interactions: none significant when used topically; systemic ivermectin should be avoided concurrently.
Availability:
- Commercially sold under various brand names such as Stromectol Cream and Ivergel.
- Prescription‑only in most jurisdictions; over‑the‑counter versions are limited to specific concentrations.
Clinical practice recommends confirming tick removal, cleaning the area with antiseptic, and then applying the ivermectin cream to reduce local inflammation and eliminate any remaining tick fragments. Monitoring for skin irritation is advised, and escalation to oral therapy may be required if symptoms persist.
