- A upper respiratory tract infection, such as the common cold
- Respiratory tract irritants such as dust, smoke, or air pollution
- Change in temperature2
Do I have a dry cough?
Identifying the type of cough you have is an important step in getting the right treatment. A dry cough can also be described as non-productive, tight, tickly and irritating.2 Some symptoms associated with dry coughs include:
- Nagging tickle in the airways
- No mucus associated with the cough
- The cough sounds dry
- May get worse at night and impact sleep quality2
If you have different symptoms you may have a chesty cough.
How to treat a dry cough?
For a dry cough, the aim is to reduce cough symptoms and to identify and treat the underlying cause of the dry cough.3 A cough suppressant such as dextromethorphan may be used to reduce the urge to cough.2
Dextromethorphan is a cough suppressant, which acts on the cough control centre to provide soothing relief from dry, irritating coughs.4
