Minocycline hydrochloride tablets, USP are indicated in the treatment of the following infections due to susceptible strains of the designated microorganisms: 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) due to 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. Nongonococcal urethritis, endocervical, or rectal infections in adults caused by Ureaplasma urealyticum or Chlamydia trachomatis. Relapsing fever due to Borrelia recurrentis. 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. Minocycline is indicated for the treatment of infections caused by the following gram-negative microorganisms when bacteriologic testing indicates appropriate susceptibility to the drug: Escherichia coli. Klebsiella aerogenes Shigella species. Acinetobacter species. Respiratory tract infections caused by Haemophilus influenzae. Respiratory tract and urinary tract infections caused by Klebsiella species. Minocycline hydrochloride tablets, USP are indicated for the treatment of infections caused by the following gram-positive microorganisms when bacteriologic testing indicates appropriate susceptibility to the drug: Upper respiratory tract infections caused by Streptococcus pneumoniae. Skin and skin structure infections caused by Staphylococcus aureus. (NOTE: Minocycline is not the drug of choice in the treatment of any type of staphylococcal infection.) When penicillin is contraindicated, minocycline is an alternative drug in the treatment of the following infections: Uncomplicated urethritis in men due to Neisseria gonorrhoeae and for the treatment of other gonococcal infections. Infections in women caused by Neisseria gonorrhoeae. Syphilis caused by Treponema pallidum subspecies pallidum. Yaws caused by Treponema pallidum subspecies pertenue. Listeriosis due to Listeria monocytogenes. Anthrax due to Bacillus anthraci s. Vincent’s infection caused by Fusobacterium fusiforme. Actinomycosis caused by Actinomyces israelii. Infections caused by Clostridium species. In acute intestinal amebiasis, minocycline may be a useful adjunct to amebicides. In severe acne, minocycline may be useful adjunctive therapy. Oral minocycline is indicated in the treatment of asymptomatic carriers of Neisseria meningitidis to eliminate meningococci from the nasopharynx. In order to preserve the usefulness of minocycline in the treatment of asymptomatic meningococcal carriers, diagnostic laboratory procedures, including serotyping and susceptibility testing, should be performed to establish the carrier state and the correct treatment. It is recommended that the prophylactic use of minocycline be reserved for situations in which the risk of meningococcal meningitis is high. Oral minocycline is not indicated for the treatment of meningococcal infection. Although no controlled clinical efficacy studies have been conducted, limited clinical data show that oral minocycline hydrochloride has been used successfully in the treatment of infections caused by Mycobacterium marinum. To reduce the development of drug-resistant bacteria and maintain the effectiveness of minocycline hydrochloride tablets, USP and other antibacterial drugs, minocycline hydrochloride 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.

Demeclocycline hydrochloride tablets are indicated in the treatment of infections caused by susceptible strains of the designated microorganisms in the conditions below: 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 due to Chlamydia trachomatis Psittacosis (Ornithosis) due to Chlamydia psittaci Trachoma due to Chlamydia trachomatis, although the infectious agent is not always eliminated as judged by immunofluorescence Inclusion conjunctivitis caused by Chlamydia trachomatis Nongonococcal urethritis in adults caused by Ureaplasma urealyticum or Chlamydia trachomatis Relapsing fever due to Borrelia recurrentis Chancroid caused by Haemophilus ducreyi Plague due to Yersinia pestis Tularemia due to Francisella tularensis Cholera caused by Vibrio cholerae Campylobacter fetus infections cause by Campylobacter fetus Brucellosis due to Brucella species (in conjunction with streptomycin); Bartonellosis due to Bartonella bacilliformis Granuloma inguinale caused by Calymmatobacterium granulomatis Demeclocycline hydrochloride tablets are indicated for treatment of infections by the following gram-negative microorganisms, 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 Demeclocycline hydrochloride tablets are 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 Skin and skin structure infections caused by Staphylococcus aureus. (Note: Tetracyclines, including demeclocycline, are not the drugs of choice in the treatment of any type of staphylococcal infection). When penicillin is contraindicated, tetracyclines, including demeclocycline hydrochloride, are alternative drugs in the treatment of the following infections: Uncomplicated urethritis in men due to Neisseria gonorrhoeae, and for the treatment of other uncomplicated gonococcal infections Infections in women caused by Neisseria gonorrhoeae Syphilis caused by Treponema pallidum subspecies pallidum Yaws caused by Treponema pallidum subspecies pertenue Listeriosis due to Listeria monocytogenes Anthrax due to Bacillus anthracis Vincent’s infection caused by Fusobacterium fusiforme Actinomycosis caused by Actinomyces israelii Clostridial diseases caused by Clostridium species In acute intestinal amebiasis, demeclocycline hydrochloride may be a useful adjunct to amebicides.
