Hello. Thank you for asking at HCM. I went through your history and your query. i would like to ask you further questions like - Do you have any other allergy conditions? Do you have frequent colds, sneezing, nasal obstruction? Have you ever had wheezing? etc. However, from your history, I would like to suggest you as follows: 1. As your siblings have asthma, you are at a high risk of developing asthma. But there are so many causes of chronic cough. So even they responded to inhaler, it is not possible to decide whether you are having asthma. So please do not worry at present. 2. Were I treating you, I would prescribe you montelukast, levocetirizine and a cough syrup containing guanphensin & terbutalin for at least 7-10 days. 3. I would also suggest you daily warm saline gargles, which may hasten your recovery. 4. To diagnose or rule out asthma, I would suggest you a spirometry testing which can definitely indicate whether you have asthma. 5. Please avoid exposure to dusts, smokes and air-pollution as much as possible. Also, please avoid smoking if you smoke. Hope above measures will be helpful to you. Wish you the best of the health. Should you have any further query, please feel free to ask at HCM. Thank you & Regards.
