Sir, my 5 and a half year old son had cold, fever cough and congestion last week, now his fever and cold is almost finished but congestion remains. We consulted our local pediatrician that he recommended us to give him Asthaline Expectorant and Mox 250, so as a second opinion I would like to know how much more time I can continue with these two medicines, Plus he seems a little weak and less-hunger after these. Thank you.
