Doxycycline is used to treat infections caused by bacteria, including pneumonia and other respiratory tract infections; certain infections of the skin or eye; infections of the lymphatic, intestinal, genital, and urinary systems; and certain other infections that are spread by ticks, lice, mites, infected animals, or contaminated food and water. It is also used along with other medications to treat acne. Doxycycline is also used to treat or prevent anthrax (a serious infection that may be spread on purpose as part of a bioterror attack), in people who may have been exposed to anthrax in the air, and to treat plague and tuleramia (serious infections that may be spread on purpose as part of a bioterror attack). Doxycycline can also be used in people who cannot be treated with penicillin to treat certain types of food poisoning. Doxycycline (Oracea) is used only to treat pimples and bumps caused by rosacea (a skin disease that causes redness, flushing, and pimples on the face). Doxycycline is in a class of medications called tetracycline antibiotics. It works to treat infections by preventing the growth and spread of bacteria. It works to treat acne by killing the bacteria that infects pores and decreasing a certain natural oily substance that causes acne. Doxycycline is used to treat moderate to severe inflammatory acne, or mild inflammatory acne that isn’t getting better with other treatments. Doxycycline is also used to treat many types of bacterial infections, from urinary tract infections to gum disease. It's an oral medication, so you'll take it by mouth in pill or capsule form. This makes it a good choice if you have back or body breakouts where it's hard to reach to put topical medications. Although acne isn’t an infection, and it’s not contagious, antibiotics can help clear up breakouts by reducing the amount of acne-causing bacteria on the skin—in this case, Doxycycline also reduces inflammation, so it helps reduce those red, swollen breakouts. It won’t treat non-inflamed breakouts, like blackheads or milia, though. You'll need a different type of acne treatment to get those blemishes under control. You'll take doxycycline once or twice a day, 50 to 100 mg per dose, as determined by your physician.
Common doxycycline uses include the treatment of acne, bacterial infections, anthrax infections, and the prevention of malaria. Doxycycline should not be used in children under the age of 8, because permanent discoloration and altered development of teeth may occur. Doxycycline is an antibiotic that is used in the treatment of infections caused by bacteria and certain other parasites. It is useful for bacterial pneumonia, acne, chlamydia infections, early Lyme disease, cholera and syphilis.
