My 3 and half year daughter, weighing 13 kg had fever and throat infection. she took antibiotic for 5 days since 15th nov along with paedeatric histalix (3.5 ml) for cough. after the course of the antibiotic, i contined giving histalix till her couging stopped. But now she still has phlegm in her throat (i think). I am worried if i ignore this, it might result in cough again or maybe chest infection. What can i give her to reduce phelgm, (maybe mucolyte?) and how much? she does have a history of wheezing.
