<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. I usually prescribe my such patients regular Levocetirizine + Montelukast for 4-6 weeks depending upon response.2. Furthermore, I also suggest them to have adequate amounts of liquids during day and a nutritious diet.3. Please avoid exposure to dusts, smokes and air pollution as much as possible.4. I would suggest you allergy testing for common air-borne allergens such as house dust mites, molds, pollen, insect proteins, animal dander, etc. This will help you identify the substances causing allergies to you as well as to know the measures to avoid them.5. If you have nose congestion, regular steam inhalation will also help you in a long run. 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.
