Why is this medication prescribed? Doxycycline is used to treat bacterial infections, including pneumonia and other respiratory tract infections; Lyme disease; acne; infections of skin, genital, and urinary systems; and anthrax (after inhalational exposure). It is also used to prevent malaria. Doxycycline is in a class of medications called tetracycline antibiotics. It works by preventing the growth and spread of bacteria. Antibiotics will not work for colds, flu, or other viral infections.
