A new study suggests that children who take paracetamol frequently are more than twice as likely to have asthma.
The study looked at the paracetamol use of more than 300,000 13 and 14 year olds from over 50 different countries.
Professor Richard Beasley, who led the study, says children who took paracetamol at least once a month within the previous year had an increased risk of asthma.
He says the study also suggests people are in the habit of taking it for trivial symptoms.
Professor Beasley says parents should still give their children paracetamol, as it's safer than aspirin and ibuprofen, but should reserve its use for significant fever or discomfort.
