Drug Levels and Effects
Summary of Use during Lactation
No information is available on the use of omadacycline during breastfeeding. It is unknown how much omadacycline is excreted into breastmilk, but the drug is only about 35% absorbed orally under optimal circumstances, and is probably less from milk because of its calcium content. The manufacturer states that breastfeeding is not recommended during treatment and for 4 days after the last dose. If an infant is breastfed, monitor the infant for possible effects on the gastrointestinal flora, such as diarrhea, candidiasis (e.g., thrush, diaper rash) or rarely, blood in the stool indicating possible antibiotic-associated colitis. As a theoretical precaution, avoid prolonged or repeat courses during nursing.
