Does Acetaminophen Cause Asthma?

Research on an international group of 13-14 years olds from 50 countries has examined the possibility that the use of acetaminophen may increase the risk of asthma in teens. Among some 360,000 participants it was found that use of this common analgesic at least once yearly increased the asthma risk by 43%, and if used at least once monthly by 151%. While this study does not prove asthma is caused by acetaminophen use, potential mechanisms exist. More study is needed.

PositiveTip: This popular analgesic may not be as safe as thought–at least for teens. Perhaps it would be wise to think twice before using for minor aches and pains?
