13. What is the difference between a chesty and a dry cough?

There are two kinds of cough: chesty (productive) and dry (non-productive).

Chesty cough1: A chesty cough, also known as productive cough, is often the result of a viral upper respiratory tract infection, such as the common cold. Infection causes the mucus membrane of the airways to become inflamed and produce thick, sticky mucus, which is no longer removed by the body’s normal clearing action and clogs up the airways. Coughing helps push out this sticky phlegm. When there is inflammation and abundance of thick mucus, this can narrow the airways and make breathing difficult.

Dry cough1,2: A dry cough is non-productive and tickly – it involves a repeated irritation of the respiratory tract and usually no phlegm is produced. This cough can, for example, be caused by cigarette smoke, dust or allergies. Sometimes it remains for a couple of days or 1 – 2 weeks after the the end of a common cold.

14. Is it possible for a dry cough to turn into a chesty cough?

Yes. In the case of a common cold, there are often different cough phases: first there can be a dry cough, which can later turn more and more into a chesty cough3. The chesty cough can once again be followed by a dry cough, which then might last for a longer time-period. Please see your doctor if your cough lasts longer than 5 days.

15. At what point should I see a doctor about a cough?

Whether you should consult a doctor is dependent on the individual situation. In general, contact a doctor if your cough lasts longer than 5 days, if you have a fever, or if you have persistent chest pain or difficulty breathing. See your doctor immediately if you are coughing up blood.

16. In the first few days of taking Bisolvon® Chesty Forte, I seem to cough up more phlegm than before. Is this normal?

When you use Bisolvon® Chesty Forte Oral Liquid or tablets, you may notice an increase in thin watery mucus from your air passages. This is common when you take Bisolvon Chesty Forte and is due to the way it works, helping to remove mucus by making it easier to cough up. If symptoms persist, seek medical advice4.
