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.
In addition to the general indications for all members of the tetracycline antibiotics group, doxycycline is frequently used to treat Lyme disease, chronic prostatitis, sinusitis, pelvic inflammatory disease, Moraxella catarrhalis, Brucella melitensis, Chlamydia pneumoniae, and Mycoplasma pneumoniae are generally susceptible to doxycycline, while some Haemophilus spp., Mycoplasma hominis, and Pseudomonas aeruginosa have developed resistance to varying degrees. Some Gram-positive bacteria have developed resistance to doxycycline. Up to 44% of Streptococcus pyogenes and up to 74% of S. faecalis specimens have developed resistance to the tetracycline group of antibiotics. When bacteriologic testing indicates appropriate susceptibility to the drug, doxycycline may be used to treat these infections caused by Gram-positive bacteria: The World Health Organization Guidelines states that the combination of doxycycline with either artesunate or quinine may be used for the treatment of uncomplicated malaria due to Plasmodium falciparum or following intravenous treatment of severe malaria. Doxycycline kills the symbiotic Wolbachia bacteria in the reproductive tracts of parasitic filarial nematodes, making the nematodes sterile, and thus reducing transmission of diseases such as onchocerciasis and elephantiasis. Doxycycline has been used successfully to treat sexually transmitted, respiratory, and ophthalmic infections. This medication is used to treat a wide variety of bacterial infections, including those that cause acne. This medication is known as a tetracycline antibiotic. Using any antibiotic when it is not needed can cause it to not work for future infections. It will not work for viral infections (such as common cold, flu). This medication is best taken by mouth on an empty stomach, at least 1 hour before or 2 hours after a meal, usually 1 or 2 times daily or as directed by your doctor. Take this medication with a full glass of water (8 ounces/240 milliliters) unless directed otherwise. If stomach upset occurs, taking it with food or milk may help. However, doxycycline may not work as well if you take it with food or milk (or anything high in calcium - more details below ), so ask your doctor or pharmacist if you may take it that way. Do not lie down for at least 10 minutes after taking this medication.
Doxycycline is also used to treat blemishes, bumps, and acne-like lesions caused by rosacea. Doxycycline will not treat facial redness caused by rosacea. Some forms of doxycycline are used to prevent malaria, to treat anthrax, or to treat infections caused by mites, ticks, or lice. Doxycycline hyclate Vibramycin, Periostat, Vibra-Tabs, Acticlate is a moderately priced drug used to treat many kinds of infections, like dental, skin, respiratory, and urinary tract infections.
