Treatment of chronic cough depends upon the underlying cause, explains MedicineNet.

Codeine and other prescribed narcotics can alleviate severe cases. Home remedies, such as keeping the head elevated during sleep, avoiding tobacco products, consuming honey, gargling warm saltwater and using cough drops, may prove effective.
