NCT ID NCT03889743
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This trial tests whether giving the steroid dexamethasone for three days to children after their first severe wheezing episode (triggered by a rhinovirus) can prevent recurrent wheezing and asthma. The study enrolls children admitted to hospitals in Norway, Finland, and Sweden. Researchers will track how many children develop asthma or need regular asthma medication over the next two years.

- Active substance
- a steroid drug called dexamethasone given as oral tablets for 3 days
- What this could lead to
- If it works, this could point toward a way to prevent asthma in children who have their first severe wheezing episode triggered by a common cold virus.
