If taken correctly, the nasal spray and oral inhaler formulation have fewer corticosteroid side effects than the tablet formulation because they limit systemic (blood) absorption. However, systemic absorption is not negligible even with correct administration. Using the spray or inhaler at higher than recommended doses or with other corticosteroids can increase the risk for serious, systemic corticosteroid induced side effects. These side effects include weakened immune system, increased risk of systemic infections, osteoporosis, and elevated pressure in the eyes.
