Hello, Thank you for asking at HCM. I went through your history and would like to know about you like what kind of breathing difficulty, whether wheezing, how frequent symptoms are, your age, any other medical conditions, any other medications, etc etc. This will help me to know more about your health and therefore to make more specific suggestions for you. At present, from your provided history, I would like to make suggestions for you as follows: 1. I usually prescribe my such patients regular montelukast + levocetirizine for 2-4 weeks depending upon response. 2. Regular nasal saline washes and steam inhalation also help. 3. For breathing difficulty/wheezing, I usually prescribe salbutamol inhaler to be taken on as-and-when-needed basis. 4. For diagnosis of allergy, I would suggest you skin prick testing for common air-borne allergens such as house dust mites, molds, pollens, insect proteins, animal dander, etc. This will help you to identify the substances causing allergies to you as well as to know the measures to avoid them. 5. Based on allergy testing results, an Allergist-Immunologist may prescribe you allergen specific immunotherapy which works on immune system to gradually improve allergy symptoms for a long time period. 6. In general, please avoid exposure to dusts, smokes and air pollution as much as possible. 7. Regular physical exercise including breathing exercises and nutritive diet rich in vitamins & minerals will also help you in a long run by improving your lung capacity and immunity respectively. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health ahead. Thank you & Regards.
