Hello
Hyperresponsive to inflammatory disease or
allergy to some allergens produces
wheezing , tears in eyes, nasal itching , fluid from nose , and itching over face .
Not only in Toronto , this type of pollution is common all over world and everywhere .
When such type of cases visit my clinic I advise my patient to take
montelukast +
fexofenadine tablet early in the morning .
While if require in the evening I advise them to take montelukast+ levoceterizine .
As these two regimes keep patient symptom free round the clock.
If possible avoid mite , dust , fine dusting powder, pollen, , hay
smoking , sudden increase or decrease in temperature , humidity , pests ( cockroaches ) , mold .
Steam inhalation and hot coffee also provide relief.
Hope this will help you.
Good luck.
