[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Nighttime excessive coughing is mostly seen with cough variant asthma. So in my opinion, you should definitely consult pulmonologist for your father and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).PFT will not only diagnose asthma, but it will also tell you about severity of the disease and treatment is based on severity only. He will mostly improve with inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone). Oral combination of antihistamine (levocetrizine or fexofenadine) and anti-allergic (montelukast) once a day at night is also beneficial. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
