Pregnancy Considerations
Because B. burgdorferi can cross the placenta, pregnant patients with active disease should be treated with parenteral antibiotics.
Doxycycline should not be used in pregnancy.
‚
Second Line
- Azithromycin, 500 mg PO daily for 7 days, can be used for those allergic to Ž ²-lactams and unable to take tetracyclines but is less effective (2).
- There is no evidence for meaningful clinical benefit from prolonged treatment or retreatment of patients with persistent unexplained symptoms despite previous antibiotic treatment of Lyme disease.
INPATIENT CONSIDERATIONS
Admission Criteria/Initial Stabilization
- Admission is recommended for patients with Lyme carditis and symptoms of chest pain, syncope, or dyspnea, and for those with second- or third-degree heart block or first-degree heart block of ≥300 ms.
- Admission is also recommended for patients with symptoms of meningitis.
ONGOING CARE
FOLLOW-UP RECOMMENDATIONS
Patient Monitoring
Based on the severity of symptoms, patients with Lyme carditis, neurologic syndromes, or arthritis may require prolonged follow-up. ‚
DIET
No restrictions ‚
PATIENT EDUCATION
- In endemic areas, patients should be advised to protect themselves against tick exposure.
- https://www.rheumatology.org/Practice/Clinical/Patients/Diseases_And_Conditions/Lyme_Disease/
- Prevention
- Use repellents that contains 20 " “30% DEET (N,N-diethyl-meta-toluamide) on exposed skin and clothing for protection that last up to several hours.
- Use 0.5% permethrin on clothing.
- Bathe or shower as soon as possible after coming indoors (preferably within 2 hours) and perform tick check after outdoor activities.
PROGNOSIS
- Early treatment with antibiotics can shorten the duration of symptoms and prevent later disease.
- Response of late-stage disease to treatment is variable. Symptoms may take weeks to resolve after beginning treatment.
COMPLICATIONS
- Recurrent synovitis, tendonitis, bursitis (7)[A]
- Chronic neurologic symptoms
- Peripheral neuropathies
- Posttreatment Lyme disease syndrome: 10 " “20% lingering symptoms of fatigue, pain, or joint and muscle aches. Can last for 6 months (8)[A]

CLINICAL PEARLS
- The presence of EM following a tick bite in an endemic area is an indication for empiric treatment for Lyme disease.
- Repeat episodes of EM in appropriately treated patients are due to reinfection and not relapse.
- Lyme disease during pregnancy may lead to infection of the placenta and possible stillbirth. Amoxicillin is the preferred treatment during pregnancy.
- Ticks must be attached for at least 24 hours or more to transmit Lyme disease.
- There is no evidence that Lyme disease can be transmited by breastfeeding or close personal contact.
- Vaccines for Lyme disease is no longer avaiable.
