Nearly two thirds of parents are unaware of the potential side effects that may affect children given conventional asthma treatments, research suggests.

And nine out of ten were unaware that there were alternatives to higher-dose inhaled steroid treatments.

The survey results demonstrate a clear need for improved communication about asthma treatment

Prolonged use of these treatments can lead to suppression of growth, thinning of the bones and suppression of the adrenal glands which has been linked to anorexia, seizures, abdominal pain, vomiting and nausea.

Therefore, it is recommended that children are given the lowest dose of steroid possible.

This can pose problems if low dose treatment proves ineffective.

But there are also modern alternatives to increasing the dose of steroids that are known as "add-on therapy".

These include a group of drugs known as leukotriene receptor agonists which work by reducing the effect of chemicals that cause inflammation of the airways.

The researchers quizzed 573 GPs, nurses and parents of children who have asthma.

They found:

• 94% of GPs and 80% of nurses are concerned about the potential side effects associated with high-dose inhaled steroid treatments
• 89% of GPs and 92% of nurses would prefer to introduce an alternative add-on therapy rather than increase the dose of steroids that they prescribe
• Less than 60% of parents felt that they were provided with all of the information that they need about asthma treatments
• Nearly 40% of parents admit their children with asthma do not take their medication exactly as directed by their doctor.

Professor David Price, of the University of Aberdeen, said: "The survey results demonstrate a clear need for improved communication about asthma treatment options between healthcare professionals and parents of children with asthma."

Donna Covey, chief executive of the National Asthma Campaign, said: "We would encourage parents to discuss any concerns regarding their child's treatment with their GP or nurse.

"In this way, parents can work in partnership with their GP or nurse to ensure that their child receives the best asthma care possible."
