A "preventer" inhaler containing a corticosteriod is part of the daily routine for many asthma patients.
But it can result in reduced growth and children often forget to take it.
Now research in the "Lancet" medical journal shows it is possible to manage symptoms without a daily dose.
Researcher studied more than 280 children and found they did fine without daily treatment if the steroids were combined instead in their "reliever" inhaler.
This eliminated the growth issue and researchers say it is an easier form of treatment for children.
More research is needed to verify these results.
