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
