Good morning, my 6 year old daughter has had a cough and runny nose since Wednesday. It was dry at first, but quickly turned wet. What syrup can I give her? I have levopront, flegamine, marshmallow syrup and Acodin. Today I took her for a short walk and noticed that in the open air there was no cough at all, but as soon as we entered the house the cough appeared again. Does this mean that it could be allergic?
