Dear Animesh, Asthma is caused due to broncho-constriction (obstruction of smaller airway passages) which is indicative of Hyper-responsiveness of air passages. Management consists of: 1. Asthalin inhaler- provide symptomatic relief by causing broncho-dilation (dilating the smaller airway passages, relieving the obstruction & increasing airflow to lungs) So, you can use it whenever you are having an acute attack. 2. Montelukast preparations- used as a maintenance therapy to relieve symptoms of asthma. 3. Antihistamines like Cetrizine can also be used to provide symptomatic relief. 4. Need for anti biotics can arise if there is a secondary infection. But this should be taken only under the guidance of your Physician. 5. Also protect yourself from exposure to cold, dust or other allergens. Wish you a good health. Take care.
