Formoterol

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Bronchodilator of long-lasting action.

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

Terbutaline which is a compound closely related to Formoterol is excreted into breast milk in non-significant amount.
Salmeterol, another compound with similar characteristics, is also non-significantly excreted.
With a relatively high molecular weight, excretion into breast milk seems unlikely.

Expert consensus states that the use of inhaled bronchodilators is compatible with breastfeeding due to a minimal absorption and low levels achieved in the mother's plasma.

Inhaled therapy with bronchodilators is preferred since they use a lower dose (less likelihood of excretion into milk)

Alternatives

  • Salmeterol ( Safe. Compatible. Minimal risk for breastfeeding and infant.)
