Babies given acetaminophen for fevers and aches may have a heightened risk of asthma symptoms in their preschool years, a new study suggests.
The findings, from a study of 411 Danish children, add to a mixed bag of research into whether there's a link between acetaminophen - better known by the brand-name Tylenol - and kids' asthma risk.
Researchers found that the more acetaminophen kids were given as infants, the more likely they were to develop asthma-like symptoms in early childhood.
That statistical link does not prove that acetaminophen causes airway trouble, according to senior researcher Dr. Hans Bisgaard, a professor of pediatrics at the University of Copenhagen in Denmark.
"We think it is too early to conclude a causal relationship," he told Reuters Health in an email.
Still, Bisgaard said, the findings should encourage further research into a "plausible biological mechanism" by which acetaminophen could promote asthma.
