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.
