Hi, thanks for asking in Healthcare Magic.
Inhaled steroids suppress bronchial inflammation
. When given as inhaled preparations, steroids afford more symptomatic releif and less side effects. Steroids reduce the inflammation thereby reducing mucosal edema (swelling). Although, not a bronchodilator
(dilatation of air way) steroids provide sustained relief.
Only when given as oral preparations (in the form of tablet) for a long period of time the steroids result in many side effects. As an anti inflammatory, they are highly useful in asthma that too when given as nebulizer
nebulizer contains the steroid Budesonide
. It exerts its action mainly in the air way. It is minimally absorbed and so results in less side effects. It results in few side effects like nasal irritation, itching, sneezing and throat dryness. It can also be taken as a prophylactic (preventive drug) and also for seasonal attacks.
You can very well continue to use Pulmicort for your son as per your treating Dr,s advice. However irrational use should be avoided.
I hope this is helpful to you.
