Hi Jody,
Thanks for posting in HCM.
I understand your concern.
Well, smoking per say does not cause persistent cough or
laryngitis. It causes irritation and decreased mobility of cilia of mucosa of upper
respiratory tract, which would lead to stagnation of mucous and superseded by infection causing laryngitis and symptoms like cough.
Kindly quit smoking, as that would be the permanent solution.
To overcome cough, you can take mucolytic agents like syrup containing
Bromhexine with
Chlorpheniramine maleate.
For laryngitis problem, you can do salt water gargling with warm water. You can also take medicated lozenges. In case it doesn't subside, you may need to take a course of antibiotics like
Azithromycin.
Avoid consumption of cold items like cool drinks and ice cream tillnthe symptoms subside completely.
Hope the information provided would be helpful.
All the best.
