Clean the bite with soap and water, apply an antiseptic ointment, and cover with a sterile bandage; if swelling, redness spreads, or fever develops, obtain medical evaluation for possible infection or tick‑borne disease.

What should be done for swelling and redness at a tick bite site? - in detail

When a tick bite becomes swollen and red, take the following actions promptly.

1. Remove the tick completely

   • Use fine‑point tweezers, grasp the tick as close to the skin as possible, and pull upward with steady pressure.
   • Disinfect the bite area with an antiseptic such as povidone‑iodine or alcohol.

2. Clean the wound

   • Wash the site with mild soap and running water.
   • Apply a thin layer of an over‑the‑counter antiseptic ointment to reduce bacterial colonisation.

3. Control inflammation and discomfort

   • Administer an oral antihistamine (e.g., cetirizine 10 mg) to lessen itching and swelling.
   • If pain is moderate, use an NSAID such as ibuprofen 400 mg every 6 hours, respecting dosage limits.

4. Observe for progression

   • Monitor the lesion for expanding redness, increasing warmth, pus formation, or the development of a bull’s‑eye rash.
   • Record any systemic symptoms: fever, chills, headache, muscle aches, or joint pain.

5. Seek professional care if any of the following occur

   • Redness spreads beyond a 2‑inch radius or the area becomes increasingly tender.
   • A target‑shaped rash appears, suggesting possible Lyme disease.
   • Flu‑like symptoms develop within 2–4 weeks of the bite.
   • The patient is immunocompromised, pregnant, or a child under 8 years old.

6. Medical interventions

   • A clinician may prescribe a short course of oral antibiotics (e.g., doxycycline 100 mg twice daily for 10 days) if bacterial infection is suspected.
   • For pronounced local inflammation, a topical corticosteroid (e.g., hydrocortisone 1%) may be applied two to three times daily for up to 5 days.
   • In rare cases of severe allergic reaction, intramuscular epinephrine and emergency care are required.

7. Prevent future complications

   • Keep the bite covered with a sterile bandage until healing is evident.
   • Perform regular skin checks after outdoor activities in tick‑infested areas, removing any attached ticks within 24 hours to lower transmission risk.

Prompt, systematic care reduces the likelihood of infection and minimizes tissue damage. If uncertainty remains, contact a healthcare provider for individualized guidance.
