Hi, i have a 3 years old son, he weight is 14.5 kgs and he suffering from cold and cough for last one week. the doc prescribed, amrolite s -5ml 3 times a day, deriphylin 5ml 3 times a day, vizylac 5ml, mrning evening. But now takin these medicines, he still not feeling better, the doc has prescribed omnacortil 5ml, thrice a day for three days. My question is is it safe to give a 3 year old child a steroid, or can i wait for some more time till he feels better?
