Management
Spotted Fever Group
- Doxycycline 100 mg po bid for 7 to 10 days
- Alternatively: tetracycline 2 g/day or chloramphenicol 2 g/d
- Alternatively: ciprofloxacin 750 mg po bid for 5 to 7 days
- But no good evidence for this
- Can use doxycycline safely for these duration in children <8 years, and is strongly indicated for rickettsioses
- May use azithromycin or clarithromycin in pregnant women
- Avoid TMP-SMX, which appears to worsen severity of disease!
