Indication: 1. This product is used as the first choice or optional drug for the following diseases: (1) Rickettsial diseases, including epidemic typhus, endemic typhus, Rocky Mountain fever, scrub typhus and Q fever. (2) Mycoplasma infections. (3) Chlamydia infections, including psittacosis, venereal diseases, lymphoedema, nonspecific urethritis, salpingitis, cervicitis and trachoma. (4) Relapsing fever. (5) Brucellosis. (6) Cholera. (7) Tularemia. (8) Plague. (9) Chancroid. It should be used in combination with aminoglycosides for the treatment of brucellosis and plague. 2. Due to the serious resistance of common pathogens to tetracyclines, this drug is only indicated when the pathogen is sensitive to this drug. Since hemolytic streptococci are mostly resistant to this drug, it is not suitable for infections caused by this type of bacteria.
