Thanks for your query
You may use cough suppressants containing codeine
along with the home remedies
you are taking. Benz pearl tablets may be of immense help along with steam inhalation. You should also take pantoprazole
tablets twice daily before food. Take plenty of water around 3-4 litre per day. With these you should start an antibiotic course preferably azithromycin
500 mg once daily after food for 6 days. From your history it seems to me that you are suffering from upper airway cough syndrome though you should consult a pulmonologist
if cough persists in the same intensity despite these treatments to get yourself examined and treatment accordingly.
