Lincosamide antibacterial. Excreted in non-significant level into breast milk. Except for few cases of enterocolitis due to disturbance of intestinal flora no other harm effects have been shown in breastfed infants. All cases spontaneously cured after discontinuation of medication. One reported case (1980) of pseudomembrane colitis in an infant whose mother was on clindamicin and gentamicin. Be aware of the possibility of false negative results of febrile infant bacterial cultures when the mother is on antibiotics and diarrheal disease due to intestinal flora imbalance. The American Academy of Pediatrics rates it as compatible with breastfeeding.
