Hello dear... Asthma is caused due to broncho-constriction (obstruction of smaller airway passages) which is indicative of Hyper-responsiveness of air passages to an allergen. And the inhalers provide symptomatic relief by causing broncho-dilation (dilating the smaller airway passages, relieving the obstruction & increasing airflow to lungs) Montelukast preparations can also be used as a maintenance therapy to relieve symptoms of seasonal allergies & asthma by reducing broncho-constriction. Drinking of warm fluids & steam inhalation also provides symptomatic relief. But...it will be better to consult a Pediatrician if symptoms still persist or aggravate. And make sure that your daughter is well protected from cold, dust & other allergens. Wishing her a good health. Thanks & take care.
