Hello, Thank you for asking at HCM. I went through your history and would like to make suggestions for you as follows: 1. Any medicine apart from allopathy - there are systems which offer treatment for allergic rhinitis such as ayurveda, homeopathy, chinese medicine, etc. It is best to contact the qualified persons from respected branches to know more about treatment in a particular system. 2. Montek-LC is generally considered very safe from long term use. Common side effects are sedation, drowsiness, stomach upset. If you are not experiencing any of these side effects, you can continue it for long term use in my opinion. 3. From allopathy, as an Allergist-Immunologist, I would suggest you allergy testing, especially for house dust mites, indoor molds, common pollens in your area, insect proteins, and pet dander (if you have pets). This will help you identify the substances that may be causing allergies to you as well as to know the measures to avoid them. 4. Based on allergy testing report, an Allergist-Immunologist may prescribe you allergen specific immunotherapy which works on immune system to improve allergy symptoms gradually over a long time. 5. In general, I would suggest you to avoid exposure to dusts, smokes and air pollution. 6. A healthy diet and regular breathing exercises will help you in a long run by improving your immunity and lung capacity 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.
