Acetylcysteine Levels and Effects while Breastfeeding

Summary of Use during Lactation

No information is available on the use of acetylcysteine during breastfeeding. To avoid infant exposure, nursing mothers may consider pumping and discarding their milk for 30 hours after administration. Acetylcysteine is very minimally absorbed after inhalation, so breastfeeding can be continued and no special precautions are required.
