What is oxytetracycline?

Oxytetracycline is no longer available in the United States.

Oxytetracycline is known by the brand name Terramycin. It is a prescription medication found in the group known as tetracycline antibiotics. Oxytetracycline treats infections that are caused by bacteria.

The bacterial organisms that oxytetracycline fights are Rickettsiae (Rocky Mountain spotted fever, typhus fever and the typhus group, Q fever, rickettsialpox and tick fevers), mycoplasma pneumoniae, agents of psittacosis and ornithosis, agents of lymphogranuloma venereum and granuloma inguinale, and the spirochetal agent of relapsing fever (Borrelia recurrentis). It also combats the following gram negative microorganisms: Haemophilus ducreyi (chancroid), Pasteurella pestis, Pasteurella tularensis, Bartonella bacilliformis, Bacteroides species, Vibrio comma, Vibrio fetus, and Brucella species (in conjunction with streptomycin). Oxytetracycline is not indicated for streptococcal infections unless sensitivity is demonstrated.

When bacteriologic testing is performed and susceptibility is indicated, oxytetracycline can treat bacterial infections caused by Escherichia coli, Enterobacter aerogenes, Shigella species, Mima species, Herellea species, Haemophilus influenzae (respiratory infections), and Klebsiella species (respiratory and urinary infections). Neisseria gonorrhoeae, Treponema pallidum, Treponema pertenue (syphilis and yaws), Listeria monocytogenes, Clostridium species, Bacillus anthracis, Fusobacterium fusiforme (Vincent's infection), and Actinomyces species are all treated by oxytetracycline when penicillin is contraindicated. Oxytetracycline is practically never used for Staphylococcus infections. This medication may be used in conjunction with other amebicides in the treatment of certain intestinal infections and it may treat eye infections as well. Oxytetracycline comes in tablet or capsule form and intramuscular or intravenous injection.
