Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Centrally acting cough suppressor with properties and usage similar to dextromethorphan.

Its high plasma protein-binding capacity explains the observed negligible excretion into milk (Olsson 1986) and also because its low oral bioavailability the passage to infant plasma from ingested milk may be hindered.

American Academy of Pediatrics: medication usually compatible with breastfeeding.


We do not have alternatives for C22H23NO7 since it is relatively safe.

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.

José María Paricio, founder of e-lactancia.
