Yes, cefuroxime axetil has excellent activity against Lyme disease and is a first-line oral treatment option.
Cefuroxime axetil (500 mg twice daily for 14-21 days) is one of three preferred oral antibiotics for treating early Lyme disease, alongside doxycycline and amoxicillin 1. The 2020 IDSA/AAN/ACR guidelines also specifically list cefuroxime axetil as an oral antibiotic choice for Lyme carditis 2.
Microbiologic Activity
Cefuroxime demonstrates robust activity against Borrelia burgdorferi:
- In vitro MBC of 1.0 mcg/mL, comparable to amoxicillin (0.8 mcg/mL) and doxycycline (1.6 mcg/mL), though less potent than ceftriaxone (0.08 mcg/mL) 3
- In vivo hamster model showed comparable efficacy to doxycycline and amoxicillin in preventing borreliosis (50% curative dose = 28.6 mg/kg) 3
- European studies confirm low MIC₉₀ of 0.063 mg/L for cefuroxime sodium against B. burgdorferi sensu stricto 4
Clinical Efficacy Evidence
Multiple randomized controlled trials establish cefuroxime axetil's effectiveness:
In adults with erythema migrans:
- 90-93% satisfactory clinical outcomes at 1 month post-treatment 5, 6
- 95-100% maintained satisfactory outcomes at 1 year, with no development of late Lyme disease complications 5, 6
- Efficacy statistically equivalent to doxycycline in head-to-head trials 5, 6, 7
In children (6 months to 12 years):
- 87-92% complete resolution of erythema migrans at treatment completion 8
- 100% good long-term outcomes with no late Lyme disease sequelae 8
- Safe and efficacious alternative when doxycycline is contraindicated 8
Practical Prescribing Details
Dosing:
- Adults: 500 mg orally twice daily for 14-21 days 1
- Children: 30 mg/kg/day in 2 divided doses (maximum 500 mg per dose) 1
- Duration: 14 days minimum (unlike doxycycline which can be 10 days) due to shorter half-life of beta-lactams 1
Indications:
- Early localized or disseminated Lyme disease with erythema migrans 1
- Lyme carditis (outpatient management) 2
- Lyme arthritis (28-day course) 2
- Facial nerve palsy without meningitis 1
Advantages Over Other Agents
- Better tolerated than doxycycline: No photosensitivity reactions (0% vs 6-15% with doxycycline) 5, 6
- Safe in pregnancy and children <8 years: Unlike doxycycline which is contraindicated 1
- Can treat concurrent cellulitis: Useful when erythema migrans cannot be distinguished from bacterial cellulitis 1
Important Caveats
- More diarrhea than doxycycline: 5-21% incidence vs 0-7% 5, 6
- Not for CNS/parenchymal disease: IV ceftriaxone required for meningitis, radiculopathy, or brain/spinal cord involvement 2, 1
- Not for severe carditis: Hospitalized patients with significant PR prolongation (>300 ms) or myopericarditis should receive IV ceftriaxone initially 2
- First-generation cephalosporins are INEFFECTIVE: Cephalexin has no activity against B. burgdorferi and should never be used 1
The evidence unequivocally supports cefuroxime axetil as an effective, well-tolerated first-line agent for Lyme disease, particularly valuable when doxycycline is contraindicated or poorly tolerated.
