Researchers from New Zealand said a study suggests a link between acetaminophen and the development of childhood asthma and allergies.
Using data from more than 200,000 children in 31 countries, researchers found infants given acetaminophen-based pain relievers for fever were 46 percent more likely to develop asthma by age 6 or 7, ABC News reported Friday. Children given acetaminophen-based painkillers by the time they turned 6 were three times as likely to have severe asthma symptoms.
