Hello. Thank you for asking at HCM. I went through your history and would like to make suggestions to you as follows: 1. I usually prescribe my such patients montelukast and levocetirizine. 2. If symptoms are very much, I usually suggest my patients to take intranasal corticosteroids for 2 weeks. It is important to mention here that all the above medicines can only control symptoms. 3. I would suggest you allergy testing which will help you identify the substances causing allergies to you and also to know the measures to avoid them. Based on allergy report, an Allergist-Immunologist may prescribe you allergen specific immunotherapy which works on immunity to improve your allergy symptoms on a long run. 4. I would also suggest you to avoid exposure to dusts, smokes and air pollution in general. 5. Regular breathing exercises and a healthy diet rich in vitamins & minerals (adequate amounts of green leafy vegetables, fruits, sprouts, etc) 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. Thank you & Regards.
