Hello. Thank you for asking at HCM. I went through your history and understand your concern. I would like to reply as follows: 1. Montek-LC can control most of the symptoms of allergic sinusitis but it does not cure allergy. So one has to take it as long as one has symptoms of allergic sinusitis. However, if it does not cause you side effects like sedation, drowsiness (which are most common), it is considered safe for long term intake. 2. For nose and sinus problems, personally I would suggest you regular steam inhalation which will hasten your process of recovery. 3. I would also suggest you regular nasal irrigation with saline sprays which can be helpful. 4. For asthmatic symptoms like wheezing, difficulty in breathing, I would suggest you to use salbutamol or levosalbutamol inhalers when you have symptoms. 5. Please avoid exposure to dusts, smokes and air pollution as much as possible. Please do not smoke if you smoke. 6. Regular breathing exercises and a healthy diet rich in vitamins and minerals (adequate amounts of green leafy vegetables, fruits, sprouts, etc) will also help you in a long run. 7. Personally I would suggest you to consult an Allergist-Immunologist who will suggest you allergy testing and may suggest you specific allergen immunotherapy depending upon results. Immunotherapy can provide long term relief from allergies by improving your immune responses. Hope above measures 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.
