What causes a chesty cough?

A cough is our body’s reflex action to clear the airways of mucus and irritants such as dust or smoke. Coughs usually short-term and are rarely a sign of something serious. A chesty cough involves phlegm that has been produced to clear out the airways. There are many causes of short-term chesty coughs including:

  • An upper respiratory tract infection (URTI) which affects the throat, windpipe or sinuses, such as a cold or the flu
  • An allergy
  • A flare-up of a long-term condition, such as asthma

There is usually no need to seek advice from your GP if you have a cough, however if you experience any of the following symptoms, you should seek medical advice:

  • You’ve had a cough for more than 3 weeks
  • The cough is severe
  • You cough up blood or experience shortness of breath, breathing difficulties or chest pain
  • You have other symptoms such as unexplained weightloss, a persistent change in your voice or lumps/swellings in the neck.

How can Robitussin Chesty Cough soothe unpleasant cough symptoms?

Robtussin Chesty Cough Medicine contains the active ingredient guaifenesin which belongs to a group of medicines known as cough expectorants. This ingredient works by changing the cough into a cough that is more productive and less frequent, to help reduce discomfort. The syrup format is easy to administer and can be taken up to 4 times a day to provide relief and improve symptoms of your cough.
