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).

Antibiotic Resistance. Disease-causing microbes that have become resistant to drug therapy are an increasing public health problem. Tuberculosis, gonorrhea, malaria, and childhood ear infections are just a few of the diseases that have become hard to treat with antibiotic drugs. Part of the problem is that bacteria and other microorganisms that cause infections are remarkably resilient and can develop ways to survive drugs meant to kill or weaken them. This antibiotic resistance, also known as antimicrobial resistance or drug resistance, is due largely to the increasing use of antibiotics.
