Doxycycline and Penicillin G Procaine for Inhalational Anthrax (Post-Exposure)

Doxycycline and penicillin G procaine are antibiotics used to treat bacterial infections in many different parts of the body. They do not work for viral infections (for example, the common cold). Doxycycline and penicillin G procaine have been approved for all forms of anthrax. (inhalational, gastrointestinal, and cutaneous). In October 2001, FDA published a Federal Register notice clarifying that these drugs were approved for inhalational anthrax (post-exposure). Use of doxycycline in children under 8 presents special concerns because of possible tooth discoloration. Long-term use of intravenous doxycycline or penicillin G procaine presents safety concerns, and patients should be switched, when appropriate, to other antibiotics to complete a 60 day course of therapy for inhalational anthrax (post-exposure).
