Suggest Treatment For Frequent Coughs And Itchy Throat
post nasal drip most common cause
Detailed Answer:
HI, thanks for using healthcare magic
One of the most common causes of persistent coughing in the absence of other cough and cold symptoms would be post nasal drip.
Rarely a person may not be aware of the drip and present only with symptoms such as coughing.
In addition to the decongestants and anti histamine, you may also need to use a topical nasal spray.
Examples are nasonex, nasocort, rhinocort, flonase
One of these would be able to help with the coughing.
The other causes of abnormal coughing are GERD (reflux). The reflux of the acid can cause coughing that would be worse on laying down and can also be worse on evenings.
I hope this helps, feel free to ask any other questions
