What should I apply to a wound after a tick bite? - in detail
After removing the tick, clean the puncture site with soap and running water. Rinse thoroughly, then apply an antiseptic such as povidone‑iodine or chlorhexidine. Allow the solution to dry before covering the area with a sterile, non‑adhesive dressing.
If the bite is in a location prone to friction or moisture, replace the dressing daily and keep the skin dry. Over‑the‑counter topical antibiotics (e.g., bacitracin or polysporin) may be applied to reduce bacterial colonization, but they are not required for every case.
Monitor the wound for redness, swelling, warmth, or increasing pain. Record any fever, headache, joint aches, or a characteristic bull’s‑eye rash, which can indicate early Lyme disease or other tick‑borne infections. Seek medical evaluation promptly if any of these symptoms develop.
Consider systemic prophylaxis when:
- The tick was attached for ≥36 hours.
- The species is known to transmit Borrelia burgdorferi.
- The bite occurred in an area with high incidence of Lyme disease.
- The patient is not allergic to doxycycline and can tolerate it.
In such circumstances, a single dose of doxycycline (200 mg) may be prescribed within 72 hours of removal, according to current guidelines.
