Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Long-acting bronchodilator.

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

Because of a high plasma protein-binding capacity and very low or undetectable plasma concentrations observed after inhalation (Cazzola 2002, AEMPS 2012) the excretion into breastmilk in significant amounts is unlikely.

Its low oral bioavailability would hamper the pass to the infant’s plasma through the breastmilk ingested.

Experts and scientific societies consider the use of Salmeterol during breastfeeding as devoid of risk for the infant (Ellsworth 1994, McDonald 1996, Nelson 2001, National Asthma Education 2004).

Terbutaline (see specific info), a molecule related to the same group of drugs, is excreted in non-significant amounts into breastmilk.

We do not have alternatives for Salmeterol 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.

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.
