Quinupristin and dalfopristin belong to a class of antibiotics called streptogramins. These antibiotics are given together as a combination (dalfopristin/quinupristin). They are used to treat serious infections (especially skin infections), including those caused by bacteria resistant to other antibiotics.
Dalfopristin/quinupristin (D/Q) works by preventing bacteria from producing proteins they need to grow and multiply.
D/Q is given intravenously, usually through a tube (catheter) inserted into a large central vein, such as one in the neck. This is called a central catheter. D/Q can also be given intravenously into a vein in the upper arm and threaded to a large central vein. This is called a peripherally inserted central catheter, or a PICC.
Dalfopristin/Quinupristin
Common Uses | Some Potential Side Effects |
|---|---|
Serious infections caused by gram-positive bacteria (such as Staphylococcus and Streptococcus species) that are resistant to other antibiotics | Aching muscles and joints Increased bilirubin* in blood Pain and inflammation at the site where the catheter was inserted, especially if inserted in a vein in an arm or leg |
* Bilirubin is a waste product that is formed during the normal breakdown of red blood cells. Bilirubin is processed and then excreted out of the liver. | |

Dalfopristin/quinupristin should be used during pregnancy only when the benefits of treatment outweigh the risks.
