Overview
The secondary prevention of Lyme disease may include post exposure prophylaxis with doxycycline in selected cases meeting criteria for chemoprophylaxis.
Secondary prevention
- After a tick bite, routine use of antibiotic prophylaxis is not recommended.
- The secondary prevention of Lyme disease may include post exposure prophylaxis with doxycycline in selected cases meeting criteria for chemoprophylaxis.
- The criteria for chemoprophylaxis include:[1]
- A single dose of doxycycline (avoid in pregnancy and children <8 years) may be offered to adults (200mg) and children (4mg/kg, maximum 200mg) if all of the criteria are fulfilled:
- The tick is identified as I. scapularis (adult or nymph)
- The tick is attached for ⩾36 hours. It is estimated by the degree of engorgement of the tick with blood or approximating the time of exposure to the tick.
- Within 72 hours of tick removal
- Local infection rate of tick with B. burgdorferi is ⩾20%
- There is no contraindication to use of doxycycline.
