Use of Anti-Infective Agents During Lactation: Part 2—Aminoglycosides, Macrolides, Quinolones, Sulfonamides, Trimethoprim, Tetracyclines, Chloramphenicol, Clindamycin, and Metronidazole

Abstract

Because many antibiotics are excreted into breast milk, it can be difficult for a practitioner to choose an antibiotic for a lactating patient that will have minimal risks to her nursing infant. This article is the second of a three-part series discussing the use of anti-infective agents during lactation. The authors review general information regarding use and common side effects for several classes of antibiotics. They also summarize information, including documented milk concentrations, milk-to-plasma ratios, and other pharmacokinetic properties, in a table that can help practitioners choose antibiotics that may be considered safe to use in the lactating mother.
