Hello and welcome to HCM
The presence of persistent cough
and itching in the throat points towards 'dry cough'.
Dry cough is the cough which is not associated with sputum production.
causes of dry cough are:
1. Chronic respiratory infections
5. Common in patients with cystic fibrosis
Dry cough gets worse during sleep and after exertion.
The above mentioned factors cause irritation and thus cause the cough reflex.
The treatment of dry cough is to suppress this cough reflex.
This is done by syrups which act by suppressing this reflex and provide soothing effect to the throat.
Taking the syrup at night is beneficial as they also contain mild sedatives which help the individual to have a good and undisturbed sleep at night. This will give symptomatic relief.
However, if you have any of the above mentioned problem then treating the underlying cause is important.
Thanks and take care
