Please consult your physician before taking any medication. DESCRIPTION:Oxytetracycline is a product of the metabolism of Streptomyces rimosus and is one of the family of tetracycline antibiotics. A 1 percent solution in water is acidic (pH about 2.5). Its potency is affected in solutions more acid than pH 2 and it is rapidly destroyed by alkali hydroxides.Oxytetracycline diffuses readily through the placenta into the fetal circulation, into the pleural fluid and, under some circumstances, into the cerebrospinal fluid. It appears to be concentrated in the hepatic system and excreted in the bile, so that it appears in the feces, as well as in the urine, in a biologically active form. Terramycin may also be used for purposes other than those listed in this medication guide.
