Tylenol tied to childhood asthma and allergies

It is already known that aspirin can trigger an asthma attack in some people.

NEW YORK — A pair of studies suggests that the common painkiller acetaminophen -- better known as Tylenol in the U.S. -- may be fueling a worldwide increase in asthma.

According to one study out Thursday, Tylenol could be responsible for as many as four in 10 cases of wheezing and severe asthma in teens.

While no one knows if the drug causes asthma by itself, another report -- published along with the first study -- shows for the first time that many toddlers took Tylenol before they developed asthma symptoms such as wheezing.

"We have confirmed that acetaminophen use comes first, so a causal link is increasingly likely," said Dr. Alemayehu Amberbir, of Addis Ababa University in Ethiopia and the University of Nottingham in the UK.

But large-scale clinical tests are necessary before anyone cleans out their medicine cabinet, stressed Amberbir, whose findings are published in the American Journal of Respiratory and Critical Care Medicine.
