Pregnancy Category:C

Breastfeeding: No published data exist on the use of pirbuterol by mouth or inhaler during lactation; however, data from the related drug, terbutaline, indicate that very little is expected to be excreted into breastmilk. Many authors and an expert panel agree that use of inhaled bronchodilators is acceptable during breastfeeding because of the low bioavailability and maternal serum levels after use. This information is based upon LactMed database (available at http://toxnet.nlm.nih.gov/cgi-bin/sis/htmlgen?LACT last accessed 09 September 2011). Manufacturer recommends use during nursing only if the potential benefit justifies the possible risk to the newborn.
