A 51-yeаr-оld pаtient presents аfter remоving a deer tick frоm the lower leg. The patient has no rash or systemic symptoms. The provider determines the tick was Ixodes species, likely attached for at least 48 hours, and removed approximately 24 hours ago. The bite occurred in a Lyme-endemic area, and the patient has no contraindication to doxycycline. What is the most appropriate management?
