Vilanterol Trifenatate


Safe substance and/or breastfeeding is the best option.

Long-acting bronchodilator with a similar action than Salmeterol.

At latest update no published data on excretion into breast milk were found.

Plasma concentration after having inhaled bronchodilators is very low, so that a significant amount in the breast milk is not expected (Ellsworth 1994, McDonald 1996).
Its low oral bioavailability hinders the passage from ingested milk towards the infant’s plasma, except in preterm babies and immediate neonatal period, which may show an increased intestinal permeability.

Terbutaline, a molecule of the same family, is excreted in insignificant amounts in breast milk (Lindberg 1984).

Inhaled bronchodilators are preferred because of their lower doses (less risk of excretion into milk).


We do not have alternatives for Vilanterol Trifenatate 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.
