Clean the bite area with soap and water, then disinfect it using povidone‑iodine or chlorhexidine. Apply a thin layer of a topical antibiotic such as bacitracin and monitor for any signs of infection.
What to apply after a tick bite? - in detail
After a tick has been detached, immediate care focuses on wound hygiene, infection prevention, and monitoring for disease signs.
First, grasp the tick as close to the skin as possible with fine‑point tweezers. Pull upward with steady pressure, avoiding twisting or crushing the body. Inspect the bite site for remaining mouthparts; if any remain, remove them with the same technique.
Second, cleanse the area thoroughly. Apply an antiseptic solution such as 70 % isopropyl alcohol, povidone‑iodine, or chlorhexidine swab. Allow the skin to dry before proceeding.
Third, consider a topical antimicrobial ointment. Options include bacitracin, mupirocin, or a triple‑antibiotic paste. Apply a thin layer over the cleaned wound and cover with a sterile bandage if the bite is in a location prone to friction.
Fourth, evaluate the need for systemic prophylaxis. For bites from ticks known to transmit Lyme disease (e.g., Ixodes scapularis in endemic areas) and when the tick has been attached for ≥36 hours, a single dose of doxycycline (200 mg for adults, 4 mg/kg for children ≥8 years) is recommended. Consult local guidelines for alternative agents if doxycycline is contraindicated.
Fifth, manage local irritation. A low‑potency corticosteroid cream (e.g., 1 % hydrocortisone) can reduce itching and inflammation. Avoid petroleum‑based products that may trap moisture and delay healing.
Sixth, observe the bite site for at least 30 days. Record any of the following: expanding erythema (≥5 cm), fever, chills, headache, muscle aches, joint pain, or a rash resembling a bull’s‑eye. Prompt medical evaluation is required if any symptoms appear.
Finally, document the encounter. Note the date of removal, estimated attachment duration, geographic location, and any prophylactic measures taken. This information assists healthcare providers in diagnosing potential tick‑borne illnesses.
