This medication is effective against streptococci, staphylococci, pneumococci, bacillus dysentery, typhoid fever, E. coli, Proteus, and ineffective against Mycobacterium tuberculosis, spirochetes, Pseudomonas aeruginosa. Primsulfon is applied in treatment of pneumonia and other diseases of respiratory, gastrointestinal systems, urogenital systems caused by bacterial infections which develop after surgery and others.
