### output:

Hello. Thank you for asking at Chat Doctor. I went through your history and understand your concern. I would like to ask you more questions like - Do you have any other allergies? Do you have any nose/sinus problem? Does anyone from your family have asthma? What is the frequency and severity of your asthma symptoms? Are you still having exposure to secondhand smoke? Does your asthma get worse in any particular season? Etc. Your exact requirement of medicines can be decided only after knowing your asthma symptoms. However, from your history, I would like to make suggestions as follows:1. First, I would like to appreciate that you are not smoking.2. Personally I would suggest you to take regular montelukast. If it is not sufficiently controlling asthma symptoms, I would add inhaled corticosteroids.3. I would suggest you to take inhaled albuterol/levosalbutamol when you feel wheezing or shortness breath despite regular medications.4. Please avoid exposure to dusts, smokes and air pollution as much as possible. A diet rich in vitamins, minerals and anti-oxidants (e.g. adequate green leafy vegetables, fruits, sprouts, etc.) will be helpful to you in a long run.5. I would also suggest you regular breathing exercises which may improve your lung capacity.6. I would suggest you to get allergy testing done to identify if you have any allergies. You may be able to avoid the allergens which are causing troubles to you. Hope above measures will be helpful to you. Should you have any further query, please feel free to ask at Chat Doctor. Wish you the best of the health. Thank you & Regards.
