Hi, Whether your are asthmatic or depends on lot of other factors- family history of asthma, similar episodes in the past, whether symptoms are more at day/night, summer/winter, and reports of investigations if any. If your cough is responding to seroflo, there is chance that this is asthma. Seroflo is used for treatment of severe asthma, not responding to low dose/first line inhalers. This, like any other drugs have some side effects, but much less than compared to oral drugs. kindly discuss with your doctor. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. Muhammed Aslam TK
