Is Carbocysteine safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Carbocysteine. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
Carbocysteine (carbosisteine) is not marketed in the United States, but is available without a prescription in other countries. No information is available on the clinical use of carbocysteine during breastfeeding, although absorption by the infant is likely to be low and unlikely to cause any side effects in the infant. If the mother requires carbocysteine, it is not a reason to discontinue breastfeeding; however, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.

Carbocysteine in pregnancy
LactMed covers breastfeeding only. For what the NHS and the US prescribing label say about pregnancy, see:
“No published information” means the studies do not exist yet — not that Carbocysteine is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
