This is a review of the medical literature regarding inhaled corticosteroids and their effects on growth and adrenal suppression in children and adolescents. A review of the literature, principally that published over the last five years, was conducted using Medline and searching indexes of articles published in national and international scientific journals. There is considerable controversy regarding the side effects of inhaled corticosteroids. In 21 studies evaluating the effect that inhaled corticosteroids have on growth, a statistically significant reduction (growth retarded by 1-1.5 cm) was observed within the first year of treatment with Beclomethasone or Budesonide inhalers. However, in studies of longer duration, no significant difference was found between final adult height and adult height of the parents. However, in ten studies of the use of inhaled corticosteroids and their effect on adrenal suppression, hypoglycemia and arrested development (no height or weight gains), as well as changes in morning serum levels and 24-h urinary levels of cortisol, were reported, especially when high doses of inhaled corticosteroids were used. Inhaled corticosteroids can reduce growth during the first year of use but do not affect adult height. However, further long-term studies are needed in order to determine the full impact of inhaled corticosteroids on final adult height. Height measures are a means of evaluating the safety and efficacy of the use of inhaled corticosteroids in children. Tests that evaluate the hypothalamic-pituitary-adrenal axis and adrenal insufficiency should be correlated with clinical symptoms and side effects.
