Thank you for your query,
As your child is having reccurent cough
and repeated use of nebulizations, you continue the steroid
inhalations as prescribed by your doctor.
The steroid inhalation for the long duration is safer in comparisson the the deleterious effects of the wheezing
and acute attacks if untreated.
As the dose given by steroid inhalation is minimal(in micrograms) and they dont enter into the blood(enters only into lungs) the systemic side effects are rare even if they are given for longer duration.
Oral cavity to be rinsed with the water after inhalation to wash the deposited drug in oral cavity.
Hope I have answered your query.
