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.
