Study: Contrary to Previous Studies, Acetaminophen Use during Pregnancy May Not Increase Asthma Risk in Offspring

Acetaminophen use during pregnancy is not associated with increased risk for asthma in children, according to the results of a prospective study reported in Obstetrics & Gynecology. “The relationship between acetaminophen use in pregnancy and asthma in children remains unclear and warrants further investigation,” write Elizabeth M. Kang, MPH, from Yale University School of Medicine in New Haven, Connecticut, and colleagues. “To identify risk factors for childhood asthma, we analyzed data from a prospective cohort study of women followed through their pregnancies and subsequent follow-up of their children at 6 years of age to investigate the etiology of childhood asthma. With detailed classification and comprehensive reporting of acetaminophen, we aimed to estimate the role of prenatal exposure to acetaminophen in the development of asthma in children.” For access to the complete study, please visit:
