Lyme Disease Post-Exposure Prophylaxis

Maine CDC does not routinely recommend the use of antibiotics after a known tick bite, but prophylaxis may be considered if:

  • The tick is identified as an engorged deer tick and was attached for at least 24 hours
  • The patient resides in an area where the prevalence of Lyme disease in ticks is greater than 20%
  • Prophylaxis can be started within 72 hours of tick removal
  • There are no contraindications to doxycycline
