Hi S.,
All of my children (3) have had allergy and sinus problems compounded with asthma. Their doctor told me in order to dry them up use Dimetap but this may aggravate the cough. In order to clear them up to use Sudafed, this will get the fluid out of their system. Sudafed is the best medicine for colds in children with asthma, but it also works really well if you don't have asthma. I still use it and my oldest child is 19 and he uses it. Hope this helps.
