Public Health Advisory: Doxycycline for Anthrax Exposure

Audience: Health professionals and general public

FDA reminds all health professionals and the general public that Doxycycline is approved for the treatment of anthrax in all its forms. The FDA is providing additional information concerning the dosing regimen for the treatment of anthrax, including cutaneous and inhalation anthrax (post-exposure). The currently recommended dosage regimen of doxycycline for severe disease is 100 mg every 12 hours for adults and 1mg per pound (2.2mg per kilogram) every 12 hours for children less than 100 pounds. These dosage regimens are appropriate for use in patients who have been exposed to anthrax (Bacillus anthracis) regardless of the route of exposure.
