To : Karen Zeretzke Re : Flovent and Serevent Serevent is a long-acting beta-2 agonist used for asthma. As such, the concentrations used and the total dose absorbed by the mom are very small assuming low to moderate dosing. It is extremely unlikely that the dose absorbed by mom would ever effect the infant. Plasma levels are virtually undetectible at low to moderate doses. If absorbed by the infant, the only untoward effect likely would be tremor, tachycardia, or sleeplessness in the infant. Flovent is a new intranasal and inhaled corticosteroid, fluticasone. Only small amounts are inhaled (micrograms) and almost none is absorbed. It is totally ( 99% plus) taken up first pass by the liver and metabolized to inactive compounds, so the oral bioavailability is zero. It should be no problem for breastfeeding infant.
