I am using two inhalers, one rescue and one twice a day.i use dailysingulair and allegra, since flu aandb, coughing like crazy.

? upper airways: are the problem, nose or sinuses, or middle ears, not every cough comes from the lungs, or reflux. Yes any virus can trigger airways inflammation, Flu A / B can, need to check with your doctor if you have nose or sinuses problem, you may need extra Rx medicines or antibiotics, check if your inhalers aren't empty (no active ingredients but still sprays), best wishes
