Inhaled corticosteroids, while much better tolerated by patients compared to pills or injections, may also cause side effects when taken for several months at high doses. These effects can include cataracts, osteoporosis and adrenal insufficiency. However, these side effects are very rare.
Moreover, when taken orally in the airways, corticosteroids can cause a number of local infections (e.g. oral fungal infections, changes in nasal passages).
