High-dose inhaled corticosteroid use in childhood asthma: an observational study of GP prescribing

Inhaled corticosteroids are effective and safe treatments for childhood asthma in standard doses, yet at high dosages they may be associated with adverse events and suboptimal outcomes; add-on therapy is, therefore, recommended to minimise their use. We quantified prescribing of high-dose inhaled corticosteroids and add-on therapy in children in July 2003 and found that high-dose inhaled corticosteroids were prescribed to 10% of children aged 5-11 years and 6% of under-5's who were treated for asthma. Add-on therapy was lacking for almost half of these individuals. Some children were receiving treatment not in accord with current licences and evidence-based recommendations and, as such, may be at risk of adverse outcomes.
