Cough is not the disease it is the symptoms of underlying disease so it important to rule out the cause of the disease. For the proper diagnosis I need more details regarding the case so I would like to suggest you consult with doctor first then take any medicine. Because long term cough could be due to TB, bronchitis etc.

Please consult over phone for detailed case history and right prescription for your husband. Case is already going towards chronic. Dry non productive cough is often allergic in nature although other underlying pathology need to be ruled out after proper case history. Dont use over the counter syrup.

Since its from long time only cough sy ll not help,better chat online n with details ll prescribe medication. Chat online for consultation and treatment.

There are plenty of medicines for cough..Depending upon your cough pattern ,symptoms medicine will be selected and your cough will be better.. Consult online

Mostly it is an allergic cough and it will never go by any syrup. The syrup may suppress it for few hours or day. Ignoring and taking blind treatment is most common mistakes patients do and later get into major trouble. It can be cured completely by homoeopathic treatment. You can consult me online.

Please consult online for the best consultation Thanks

Cough Syrups in Homoeopathy has no place and if you find one in homoeopathic chemist shop then that is not as per principles of homoeopathy. It is advised that patient may regularly inhale steam four times a day, and after 30 minutes of taking steam he may do gargles with hot saline water. He may avoid moving out in dusty environment.
