INDICATIONS AND USAGE
To reduce the development of drug-resistant bacteria and maintain effectiveness of Doxycycline Hyclate Tablets, USP and other antibacterial drugs, Doxycycline Hyclate Tablets, USP 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.
Treatment:
Doxycycline is indicated for the treatment of the following infections:
Rocky Mountain spotted fever, typhus fever and the typhus
group, Q fever, rickettsialpox, and tick fevers caused by Rickettsiae.
Respiratory tract infections caused by Mycoplasma
pneumoniae.
Lymphogranuloma venereum caused by Chlamydia
trachomatis .
Psittacosis (ornithosis) caused by Chlamydophila
psittaci .
Trachoma caused by Chlamydia trachomatis , although
the infectious agent is not always eliminated, as judged by
immunofluorescence.
Inclusion conjunctivitis caused by Chlamydia
trachomatis .
Uncomplicated urethral, endocervical, or rectal infections
in adults caused by Chlamydia trachomatis .
Nongonococcal urethritis caused by Ureaplasma
urealyticum .
Relapsing fever due to Borrelia recurrentis .
Doxycycline is also indicated for the treatment of infections caused by the following gram-negative microorganisms:
Chancroid caused by Haemophilus ducreyi .
Plague due to Yersinia pestis .
Tularemia due to Francisella tularensis .
Cholera caused by Vibrio cholerae .
Campylobacter fetus infections caused by Campylobacter
fetus .
Brucellosis due to Brucella
species (in conjunction
with streptomycin).
Bartonellosis due to Bartonella bacilliformis .
Granuloma inguinale caused by Klebsiella granulomatis .
Because many strains of the following groups of microorganisms have been shown to be resistant to doxycycline, culture and susceptibility testing are recommended.
Doxycycline is indicated for treatment of infections caused by the following gram-negative bacteria, when bacteriologic testing indicates appropriate susceptibility to the drug:
Escherichia coli .
Enterobacter aerogenes .
Shigella
species.
Acinetobacter
species.
Respiratory tract infections caused by Haemophilus
influenzae .
Respiratory tract and urinary tract infections caused by Klebsiella
species.
Doxycycline is indicated for treatment of infections caused by the following gram-positive microorganisms when bacteriologic testing indicates appropriate susceptibility to the drug:
Upper respiratory infections caused by Streptococcus
pneumoniae .
Anthrax due to Bacillus anthracis , including
inhalational anthrax (post-exposure): to reduce the incidence or
progression of disease following exposure to aerosolized Bacillus
anthracis .
When penicillin is contraindicated, doxycycline is an alternative drug in the treatment of the following infections:
Uncomplicated gonorrhea caused by Neisseria gonorrhoeae .
Syphilis caused by Treponema pallidum .
Yaws caused by Treponema pallidum
subspecies pertenue .
Listeriosis due to Listeria monocytogenes .
Vincent's infection caused by Fusobacterium
fusiforme .
Actinomycosis caused by Actinomyces israelii .
Infections caused by Clostridium
species.
In acute intestinal amebiasis, doxycycline may be a useful adjunct to amebicides.
In severe acne, doxycycline may be useful adjunctive therapy.
Prophylaxis:
Doxycycline is indicated for the prophylaxis of malaria due to Plasmodium falciparum in short-term travelers (<4 months) to areas with chloroquine and/or pyrimethamine-sulfadoxine resistant strains.
