When should you see a doctor about a cough?
There are two main types of coughs:
- A wet cough (or productive cough) – Generates phlegm or mucus
- A dry cough – Doesn’t generate phlegm, often caused by a tickly throat
What causes a cough?
Viruses usually cause most coughs. They typically inflame the throat, windpipe or lungs. On average, a cough lasts for up to about three weeks. In most cases, they fade on their own without any medication. This is because the body is usually fighting off the infection. If a virus causes a cough, antibiotics won’t help.
Antibiotics only help if bacteria caused the cough. These coughs tend to make a person more unwell than a viral cough.
The most common causes of a cough in adults are:
- Influenza (the flu)
- Viral upper respiratory infections
- Bacterial pneumonia and bronchitis
- Lung cancer
- Post nasal drip
- Congestive heart failure
- Some medication side effects
How long should a cough last?
An average person in Australia will get 2-4 coughs in a year, and these will typically fade in less than three weeks. If your cough lasts for longer than three to eight weeks (four in children), it is considered ‘chronic’.
When to see a doctor about a cough
If your cough is chronic or accompanied by other symptoms, do not self-diagnose. See a doctor for an accurate examination, prescription, and advice on potential risks.
One of the cases, when you should see a doctor, is when you have a chronic cough as described above. In such a case, you will need to work with your doctor so you can be accurately diagnosed and know the cause of the cough.
You should also see a doctor if:
Your cough is severe or is just getting worse day by day
- You’re coughing up blood
- You’re having chest pain
- You’re experiencing shortness of breath or breathing difficulties
- You’re taking medicine for another illness
- A cough is accompanied by some other symptoms such as a rash or an ongoing headache

What will the doctor do about your cough?
A GP will be able to examine and carefully diagnose your cough. First, the doctor will ask about the symptoms before performing a physical examination. Depending on the seriousness of your cough, he may recommend;
- Sputum analysis
- A chest X-ray
- Lung function test
- Blood tests
Your doctor will only prescribe antibiotics for your cough if there is a high likelihood they will make a difference.
