Inhaler medications in the form of metered dose inhaler(pMDI) with spacer+/-mask is the cornerstone of asthma management in children as well as in adult.There is a common myth in society that once a child starts to take medicines through pMDI with spacer+- mask,he or she becomes addicted to these medicines and device.This belief is completely wrong.These medicines or devices does not contain any substance which makes the user addicted to it.It depends on the severity of the disease that the medications will be needed for how long.
Suppose, a child has been prescribed a lens with spectacle for problem in eyes.Some children will not require it after few months or few years as the child grows.But few children may require it for life.It does not mean that the spectacle or lens has made the child addicted.Same is the situation with MDI with spacer.
So ,whenever your doctor prescribes it ,use it for a period decided by your doctor.
