Is Acetylcysteine compatible with breastfeeding? Do we have alternatives for Acetylcysteine?


March 22, 2018 (Very Low Risk)

Aminoacid with mucolytic properties. It is commonly used in infants either as a mucolytic, or, at a higher doses as a deintoxicant against paracetamol poisoning. It may be found in combination with other aminoacids in IV solutions for parenteral nutrition.

On latest update no published data about breastfeeding were found.

Because it is a toxicity free drug with low oral absorption and commonly prescribed to treat neonates, even at high dose,problems related to breastfeeding are highly unlikely.


We do not have alternatives for Acetylcysteine since it is relatively safe.

Very Low Risk

Compatible. Not risky for breastfeeding or infant.

Low Risk
