What can I apply after a tick bite? - in detail
After removing the tick, clean the site with soap and water or an alcohol swab. Apply an antiseptic such as povidone‑iodine or chlorhexidine to reduce bacterial contamination. If irritation or a rash develops, a topical corticosteroid cream (e.g., hydrocortisone 1%) can lessen inflammation and itching.
For prophylaxis against Lyme disease, a single dose of doxycycline (200 mg) may be prescribed within 72 hours of the bite for adults in endemic areas, provided no contraindications exist. Alternatives include amoxicillin (200 mg twice daily for 10 days) or cefuroxime axetil (500 mg twice daily for 10 days) for those unable to take doxycycline.
If the bite area shows signs of infection—redness spreading, swelling, pus, or fever—begin a course of oral antibiotics promptly. Empiric therapy often involves doxycycline (100 mg twice daily for 10–14 days) or amoxicillin‑clavulanate (875 mg/125 mg twice daily) depending on local resistance patterns.
Additional supportive measures:
- Apply a cool compress to relieve swelling.
- Use oral antihistamines (e.g., cetirizine 10 mg) for systemic itching.
- Monitor for early Lyme symptoms (erythema migrans, flu‑like illness) for up to 30 days; seek medical evaluation if they appear.
