Our 19 month old son was diagnosed with RAD (reactive airway disease) and our pediatrician is very hesitant to call what he has "asthma". His two bouts of wheezing were both associated with viral respiratory infections. However, after this infection and the seasonal allergies he seems to have, the dr. prescribed Singulair (4mg granules) to us to help control our son's wheezing and coughing. After being on it three days, he's not the normal laid bad but energetic boy that we know is ours. He's mean...he's aggressive...and he's biting so much at daycare that they have assigned one person to shadow him all day long. We took him off of it yesterday, so we're now 24 hours singulair free. I'll post any differences we see in a few days, but for now it's our firm belief that Singulair is what is making the difference.
