Why Your Asthma Inhaler Won't Stop Construction Dust

Your daily steroid inhaler keeps your baseline asthma under control, but then you walk into a room being renovated and suddenly you're reaching for the rescue inhaler. Why doesn't the preventer prevent that? This episode unpacks the two separate inflammatory pathways in your airways — the eosinophilic pathway that steroids handle, and the leukotriene pathway that irritants exploit. We explain how montelukast plugs that specific gap, why your inhaler isn't failing even when it feels like it is, and what Reactive Airways Dysfunction Syndrome (RADS) has to do with it all.
