Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.
Thank you for helping to protect and promote breastfeeding.

Quinupristin and dalfopristin are streptogramin antibacterial semisynthetic derivatives of pristinamycin I and IIA. They are used in combination in a 3:7 ratio for the treatment of severe infections with multidrug-resistant gram-positive bacteria, specifically MRSA and vancomycin-resistant Enterococcus faecium. Intravenous administration every 8 to 12 hours.
At the time of the last update, we found no published data on its excretion in breast milk.
Its pharmacokinetic data (high molecular weight and large volume of distribution) make it unlikely to pass into breast milk in clinically significant quantities (Hale, Mitrano 2009, Chin 2000), although the low binding to plasma proteins could favor it.
Its low oral bioavailability makes it difficult for it to pass into infant plasma from ingested breast milk, except in premature infants and the immediate neonatal period in which there may be greater intestinal permeability.
Monitor the appearance of vomiting, diarrhea or jaundice in the infant. Although rare, the possibility of transient gastroenteritis due to altered intestinal flora in infants whose mothers take antibiotics should be considered. (Briggs 2015, Ito 1993)
Until more published data on this drug in relation to lactation are known, safer alternatives may be preferable, especially during the neonatal period and in case of prematurity.
