SUMYCIN SUMMARY
Sumycin for oral administration contains tetracycline, an antibiotic isolated from Streptomyces aureofaciens.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Sumycin Syrup (Tetracycline Oral Suspension, USP) and other antibacterial drugs, Sumycin Syrup (Tetracycline Oral Suspension, 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.
Tetracycline hydrochloride is indicated for the treatment of the following infections:
Rocky Mountain spotted fever, typhus fever and the typhus group, Q fever, rickettsial pox and tick fevers caused by Rickettsiae
Respiratory tract infections caused by Mycoplasma pneumoniae
Lymphogranuloma venereum caused by Chlamydia trachomatis
Psittacosis and ornithosis due to Chlamydia psittaci
Trachoma caused by Chlamydia trachomatis, although the infectious agent is not always eliminated, as judged by immunofluorescence
Inclusion conjunctivitis caused by Chlamydia trachomatis
Tetracycline hydrochloride is indicated for the treatment of uncomplicated urethral, endocervical or rectal infections in adults caused by Chlamydia trachomatis
Nongonococcal urethritis caused by Ureaplasma urealyticum
Relapsing fever due to Borrelia recurrentis
Tetracycline hydrochloride is also indicated for the treatment of infections caused by the following gramnegative microorganisms:
Chancroid caused by Haemophilus ducreyi
Plague due to Yersinia pestis (formerly Pasteurella pestis)
Tularemia due to Francisella tularensis (formerly Pasteurella tularensis)
Cholera caused by Vibrio cholerae (formerly Vibrio comma)
Campylobacter fetus infections caused by Campylobacter fetus (formerly Vibrio fetus)
Brucellosis due to Brucella species (in conjunction with streptomycin)
Bartonellosis due to Bartonella bacilliformis
Granuloma inguinale caused by Calymmatobacterium granulomatis
Because many strains of the following groups of microorganisms have been shown to be resistant to tetracycline hydrochloride, culture and susceptibility testing are recommended.
Tetracycline hydrochloride is indicated for treatment of infections caused by the following gram-negative microorganisms, when bacteriologic testing indicates appropriate susceptibility to the drug:
Escherichia coli
Enterobacter aerogenes (formerly Aerobacter aerogenes)
Shigella species
Acinetobacter species (formally Mima species and Herellea species)
Respiratory tract infections caused by Haemophilus influenzae
Respiratory tract and urinary tract infections caused by Klebsiella species
Tetracycline hydrochloride is indicated for treatment of infections caused by the following gram-positive microorganisms when bacteriologic testing indicated appropriate susceptibility to the drug:
For upper respiratory infections caused by Streptococcus pneumoniae (formerly Diplococcus pneumoniae).
Skin and skin structure infections caused by Staphylococcus aureus.
Tetracyclines are not the drugs of choice in the treatment of any type of staphylococcal infections.
When penicillin is contraindicated, tetracycline hydrochloride 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 pertenue
Listeriosis due to Listeria monocytogenes
Anthrax due to Bacillus anthracis
Vincent’s infection caused by Fusobacterium fusiforme
Actinomycosis caused by Actinomyces israelii
Infections caused by Clostridia species
In acute intestinal amebiasis, the tetracycline hydrochlorides may be a useful adjunctive therapy to amebicides.
In severe acne the tetracycline hydrochlorides may be useful adjunctive therapy.
