<human>: I have a chronic running nose. I have known seasonal allergies and allergies to pet dander. I take allergy medicine regularly and I don t catch the flu very often, however I m plagued with a clogged running nose year round for the past few years. My earliest memory of my issues was 4th grade and I am now 21 years old. What can be the cause of this?
<bot>: Hello, Thank you for asking at Chat Doctor. I went through your history and would like to make suggestions for you as follows:1. Usually most of the medicines (except allergen specific immunotherapy) control the symptoms but not "cure" the allergies. Hence, if you have known allergies, I would suggest you to take medicines regularly and consider allergen specific immunotherapy which is usually prescribed by qualified Allergists.2. For allergic rhinitis, I usually prescribe my such patients regular montelukast + levocetirizine.3. I would also suggest you to avoid exposure to dusts, smokes and air pollution as much as possible.4. Regular steam inhalation and nasal saline washes will also help you in a longer run.5. If clogged nose does not improve with above medicine, I would suggest you intranasal corticosteroids for 7-14 days under guidance of a physician.6. Please avoid the allergens you are allergic to. Hope above suggestions 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 ahead. Thank you & Regards.
