Indication: 1 This product can be used as one of the drugs for the following diseases: (1) Rickettsial diseases, such as epidemic typhus, endemic typhus, Rocky Mountain fever, scrub typhus and Q fever; (2) Mycoplasma infection; (3) Chlamydia infection, including psittacosis, venereal disease, 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 to treat brucellosis and plague. 2 Since the common pathogens are currently sensitive to tetracycline

Indication: It is mainly used for tonsillitis, pneumonia, scarlet fever, diphtheria and carriers, gonorrhea and other infections caused by G-sensitive bacteria such as Staphylococcus aureus, Streptococcus pneumoniae, and other Streptococci; it can also be used for upper respiratory tract infections (such as ear, nose, throat infections, etc.) caused by influenza bacilli, skin and soft tissue infections caused by Staphylococcus aureus, syphilis, intestinal amebiasis, etc. This product can be used as the first choice drug for Legionnaires' disease, mycoplasma pneumonia, etc.

Indication: Mild or moderate respiratory tract infections caused by β-hemolytic streptococci and pneumococci. Hemophilic influenza. Mild or moderate lower respiratory tract infections caused by β-hemolytic streptococci and pneumococci. Respiratory tract infections caused by Mycoplasma pneumoniae. Whooping cough caused by Bordetella pertussis: Erythromycin can effectively eliminate the whooping cough bacteria in the throat of patients. Clinical studies have shown that erythromycin can prevent susceptible people from being infected with whooping cough. Diphtheria: Diphtheria is caused by the toxin produced by Bordetella diphtheriae. Erythromycin can prevent susceptible people from becoming diphtheria carriers or eradicate the bacteria in carriers. Erythrasma caused by Corynebacterium microti. Intestinal amoeba caused by Entamoeba histolytica. Mononucleosis caused by Listeria. Mild and moderate infections of the skin and soft tissues caused by Streptococcus pyogenes and Staphylococcus aureus.

Indication: It is suitable for the treatment of respiratory tract infections such as otitis media, bronchitis, pneumonia, urinary tract infections, skin and soft tissue infections, bone and joint infections, sepsis, infective endocarditis, hepatobiliary system infections, and eye, ear, nose, and throat infections caused by sensitive bacteria. This product can also be used as a preventive drug before surgical operations.
