Indications & Usage
1 INDICATIONS AND USAGE To reduce the development of drug-resistant bacteria and maintain the effectiveness of doxycycline hyclate delayed-release tablets and other antibacterial drugs, doxycycline hyclate delayed-release tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Doxycycline is a tetracycline-class antibacterial indicated in the following conditions or diseases: Doxycycline hyclate delayed-release tablets are a tetracycline-class drug indicated for: • Rickettsial infections ( 1.1 ) • Sexually transmitted infections ( 1.2 ) • Respiratory tract infections ( 1.3 ) • Specific bacterial infections ( 1.4 ) • Ophthalmic infections ( 1.5 ) • Anthrax, including inhalational anthrax (post-exposure) ( 1.6 ) • Alternative treatment for selected infections when penicillin is contraindicated ( 1.7 ) • Adjunctive therapy in acute intestinal amebiasis and severe acne ( 1.8 ) • Prophylaxis of malaria ( 1.9 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of doxycycline hyclate and other antibacterial drugs, doxycycline hyclate delayed-release tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.
