Suggest Treatment For Chronic Cough

post nasal drip is the most common cause
Detailed Answer:
HI, thanks for using healthcare magic
Chronic cough can be due to different possible causes but the most common causes are: (1) post nasal drip related cough (recently renamed upper airway cough syndrome)
This is the most common cause.
(2)GERD -reflux
(3)asthma
(4)non asthmatic eosinophilic bronchitis- there is a type of white blood cell called eosinophils.
This condition refers to the infiltration of eosinophils into the bronchi (part of the airway).
The airways are also very responsive and there may be some obstruction of the airways.
Because upper airway cough syndrome (post nasal drip) is the most common cause, this is normal addressed first in case this is the cause.
Treatment: (1) topical steroid nasal sprays eg nasonex or flonase or rhinocort along a decongestant and antihistamine
Cough suppressants are not normally used
This can take 2 to 4 weeks for an effect though may take months in some persons
(2) if there is a history of reflux, reflux medications can be used
(3)if there is no response after 2 to 4 weeks, then consider non eosinophilic bronchitis- this can be checked by a sputum (coughed up mucous) test.
When the sputum is sent to the lab, they would see increase in eosinophils.
Treatment involves the use of a course of inhalers, normally improvement in 4 weeks
Summary: (1) post nasal drip (upper airway cough syndrome) is the most common cause so treat first
Treat with nasal steroid sprays, decongestant and antihistamine
(2) non eosinophilic cough syndrome- diagnosed by finding eosinophils in the sputum
If present treat with inhalers, respond in 4 weeks
I hope this helps, feel free to ask any other questions
