Terbutaline Sulfate

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Short-acting beta-adrenergic bronchodilator, similar in characteristics to salbutamol.
Indicated in the treatment of asthma.
Administration preferably inhaled (also oral or intravenous).

It is excreted into breast milk in clinically non-significant amount (Lindberg 1984, Lonnerholm 1982, Boreus 1982) and neither clinical nor development problems were observed in infants whose mothers were treated with oral terbutaline (Lindberg 1984, Lonnerholm 1982, Boreus 1982) .
Plasma levels of these infants were undetectable or very low (Lindberg 1984, Lonnerholm 1982).

Preferable preparations are inhaled bronchodilators since <10% of the dose is absorbed.

Several medical societies, experts authors and expert consensus consider the use of inhaled bronchodilators to be safe during breastfeeding (Hale, Lactmed, Amir 2011, National Asthma 2004, Nelson 2001, Ellsworth 1994).
American Academy of Pediatrics: medication usually compatible with breastfeeding (AAP 2001).
