Likely Compatibility

Fairly safe. Mild or unlikely adverse effects. Compatible under certain circumstances. Follow-up recommended. Read Commentary.

A thiolactone derivative mucolytic agent of the natural amino acid homocysteine indicated in chronic obstructive bronchitis (CECMED 2017). Administered orally every 12 hours.

Since the last update we have not found published data on its excretion in breastmilk.

Its short half-life makes transfer to milk in significant quantities unlikely.

Side effects are gastrointestinal and mild.

This drug has very few bibliographic references and its effectiveness has not been proven (Cazzola 2018, Welsh 2015, Irwin 1993).

Until there is more published data on this drug in relation to breastfeeding, safer known alternatives may be preferable, especially during the neonatal period and in case of prematurity.

If you wish to minimize exposure, you should wait about 3 hours to breastfeed after administration.


  • Acetylcysteine (Safe substance and/or breastfeeding is the best option.)
  • Ambroxol (Safe substance and/or breastfeeding is the best option.)
  • Bromhexine (Safe substance and/or breastfeeding is the best option.)
  • Carbocisteine (Safe substance and/or breastfeeding is the best option.)

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
