Frequently asked questions about Synercid (quinupristin / dalfopristin)

What is Synercid (quinupristin / dalfopristin) used for?
Synercid (quinupristin / dalfopristin) is approved for the treatment of complicated skin and soft tissue infections caused by certain Gram-positive bacteria. Additionally, the Infectious Diseases Society of America (IDSA) has suggested that Synercid (quinupristin / dalfopristin) may be an option for the treatment of certain infections in the brain that can't be treated with other antibiotics. Although it isn't FDA approved for this purpose, professional organizations like the IDSA have recommended it based on clinical evidence.
When would Synercid (quinupristin / dalfopristin) be considered to treat my infection?
Synercid (quinupristin / dalfopristin) can treat skin infections caused by certain bacteria species called Staphylococcus aureus and Streptococcus pyogenes.
