A major new international study released Friday has found that adolescents who take acetaminophen, better known under the brand name Tylenol, have a higher risk of asthma, allergic nasal conditions and the skin disorder eczema. Those who took the common painkiller as infrequently as once a month had twice the normal risk of developing the disorders.
Experts noted, however, that the study does not show that the drug causes the problems. In fact, some said, it is equally likely that the children were taking the drug because they were already suffering from asthma.
