I've been really worried about my dad's heavy cough. It's been going on for a while, and whoever sleeps in the same room as him can't get a good night's sleep. We've seen so many doctors, and he's tried all sorts of medicines. Some think it's bronchitis or asthma, while others have just prescribed general cough medicine. Despite trying everything, including rotahealermedicines, nothing seems to work. Could you please suggest what might be wrong or recommend something that could finally help with his cough?

Based on the information provided, it seems like your father's cough is persistent and impacting his quality of life. Since he has already tried various medications without much improvement, I would recommend trying a combination of Montelukast (brand name Singulair) 10mg once daily in the evening and FluticasoneSalmeterol (brand name Advair) inhaler 25050mcg two puffs twice daily. These medications can help manage symptoms of asthma-related cough and provide relief. Additionally, steam inhalation and staying hydrated can also help alleviate cough symptoms. It's important to follow up with a healthcare provider for further evaluation and management.
