What causes a cough?

A cough is a reflex that helps to clear your airways of irritants such as dust, smoke and mucus. There are many different reasons why you may be experiencing a cough and it is rarely a sign of something serious.

Occasional coughs

Common causes of occasional coughs are:

  • An upper respiratory tract infection (URTI) such as cold, flu, laryngitis, sinusitis or whooping cough
  • A lower respiratory tract infection (LRTI) that affects your lungs or lower airways such as acute bronchitis or pneumonia
  • An allergy, such as allergic rhinitis or hay fever
  • A flare-up of long term conditions such as asthma
  • After inhalation of dust or smoke

Long-term coughs

Common causes of long-term coughs:

  • A long term respiratory tract infection
  • Asthma
  • An allergy
  • Smoking
  • Bronchiectasis
  • Postansal drip
  • Gastro-oesophageal reflux disease
  • Some prescribed medicines

How can Covonia Mucus Cough help to relieve chesty coughs?

Covonia Mucus Cough syrup contains liquorice and squill which belong to a group of medicines known as expectorants. They work by helping to remove phlegm in people with chesty coughs. Covonia Mucus cough also contains menthol which helps to relieve congestion in chesty coughs and bronchitis. These ingredients work together to remove the phlegm that is causing your uncomfortable chesty cough, helping you to breathe easier.
