Hi there ~
I understand your concerns. An infant with mild fever
cough given mucolite
will just make the cough worse for some time so that he coughs it all out as the mucolite breaks down the mucus where the bacteria resides and get rid of the infection by bringing it out that way. I also thing that you should be fine with giving sinarest
and mucolite at the same time. Call you pediatrician
if you have doubts.
Take care and have a lovely day!
