Hi, we have recently sifted to Bangalore from Gurgaon( about 2 months ago). My son, 3.8 yrs is suffering from allergic cough( thats what his doc says) for past 10 days. He says that he is allergic to sand and dust. For the 1st 4 days, this was not diagonosed and doc gave him Mox and a multi vitamin for 4 days. When there was no improvement in cough, we again went to him and he suggested Chericof 3 times a day(2.5 ml) and Cetrizine Hydrochloride, once every day. I cant see much of an improvement after 2 days of this medicine. Pls advise
