The broad study questioned 300,000 teenagers about their asthma symptoms and their use of acetaminophen. They found a two-and-a-half times greater incidence of asthma in children that took the drug at least once a month. Some children also showed an increase in rhinoconjunctivitis, which is essentially itchy, runny eyes. Other children showed a flair-up of itchy, scaly skin known as eczema.
The key take-away from the study is that acetaminophen might not be the best medicine for kids who suffer from asthma and other allergic reactions.
Next time your child has a fever, you might want to reach for the Motrin instead.
