Anthrax, gastrointestinal
- Gastrointestinal anthrax
- Preferred regimen: Ciprofloxacin 400 mg intravenously every 8 h OR doxycycline 100 mg intravenously every 12 h combined with second agent: clindamycin 600 mg intravenously every 8 h or penicillin G 4 MU every 4–6 h OR meropenem 1 gm intravenously every 6–8 h or rifampin 300 mg every 12 h.
- Note:Treatment for 60 d is recommended to avoid relapse or breakthrough of incubating disease. If initial therapy is intravenous, then convert to oral administration (ciprofloxacin or doxycycline) when clinically indicated. Steroids may be considered as an adjunct therapy for patients with severe edema and for meningitis. For pregnant women, avoid doxycycline. Use ciprofloxacin and switch to oral penicillin once susceptibilities are known.
