Summary of Use during Lactation

Neither inhaled mometasone nor mometasone nasal implants have been studied during breastfeeding. Although not measured, the amounts of inhaled and nasal corticosteroids absorbed into the maternal bloodstream and excreted into breastmilk are probably too small to affect a breastfed infant. Expert opinion considers inhaled and oral corticosteroids acceptable to use during breastfeeding.[1,2] See also Mometasone, Topical.
