Indications

FDA-approved Indications

Vancocin

Vancocin is indicated for the treatment of Clostridioides difficile-associated diarrhea. Vancocin is also used for the treatment of enterocolitis caused by Staphylococcus aureus (including methicillin-resistant strains) in adult and pediatric patients less than 18 years of age.

Limitations of Use

• Parenteral administration of vancomycin is not effective for the above infections; therefore, Vancocin must be given orally for these infections.
• Orally administered Vancocin is not effective for other types of infections.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Vancocin and other antibacterial drugs, Vancocin should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
