Not sure

What type of inhaler are you talking about?

My son also takes a chewable steroid to help his asthma

Personally i dont think there is much you can do if a inhaler was prescribed then you must need it. Hot steamy showers or baths with some vicks vapor bath may help some.

Is there any particular reason to not use an inhaler? I agree with Lisa, hot showers and using Vicks can help. When I have asthma flare ups and my inhaler is not around, I breathe a little better with fresh air or going somewhere that’s cold (Winter air is the most refreshing and easiest to breathe).
