What should be applied after a tick bite? - in detail
After removing a tick, clean the bite site with an antiseptic solution such as povidone‑iodine or chlorhexidine. Apply a thin layer of a broad‑spectrum antibiotic ointment (e.g., bacitracin, mupirocin) to reduce the risk of bacterial infection. Cover the area with a sterile, non‑adhesive dressing if the skin is broken; otherwise, leave it uncovered to allow air exposure.
Additional measures
- Observe the bite for at least 30 minutes; if redness spreads rapidly or a rash develops, seek medical attention.
- Administer a single dose of oral doxycycline (200 mg) within 72 hours for individuals at high risk of Lyme disease or in regions where the disease is endemic; consult a healthcare professional before use, especially for children and pregnant women.
- Record the date of the bite, tick removal time, and any symptoms; this information assists clinicians in diagnosing tick‑borne illnesses.
- Avoid applying home remedies such as petroleum jelly, alcohol, or heat, as they do not eliminate pathogens and may irritate the skin.
If systemic symptoms appear—fever, headache, muscle aches, or joint pain—contact a medical provider promptly. Early treatment with appropriate antibiotics can prevent complications from diseases such as Lyme disease, anaplasmosis, or babesiosis.
