Hello doctor my son 3yrs 6months had pneumonia last November n was hospitalized n got recovered, but from March he is having on n off coughs , so we consulted our paediatrician he said it's allergic cough n gave inhaler budecort n levolin since cough syrups dint work for him even after using for a week. Now from few months he was fine, now again from 3days he is having cough, I gave him chericof but still the cough dint stop. So as prescribed earlier , can I give him levolin inhaler. Will it cause any harm since I already used chericof syrup for 3days. N is this inhalers given only for asthma or even allergies, I have no history of asthma in my family, so worried.
