Because due to change in temperature and humidity person develops allergy, hence bronchoconstriction, hence cough and cold. When such patient visit in my clinic I usually prescribe montelukast levoceterizine combination tablet once or twice in a day till complete relief. But when patient dont get relief there is breathlessness or difficult breathing within 2-3 days, I prescribe them montelukast albuterol combo pack tablet once or twice in day till complete relief.
