Pirbuterol Pregnancy Warnings

Pirbuterol has been assigned to pregnancy category C by the FDA. Animal studies at high doses given by inhalation and orally have not revealed evidence of adverse fetal outcome. There are no controlled data in human pregnancy. Pirbuterol is only recommended for use during pregnancy when benefit outweighs risk.

In a review of 229,101 deliveries to Michigan Medicaid patients, 19 first-trimester exposures to pirbuterol and 62 exposures anytime during pregnancy were recorded. No birth defects were reported with first trimester exposure. (written communication, Franz Rosa, MD, Food and Drug Administration, 1994)
