About this symptom
A cough may be dry or productive, begin suddenly or continue for several weeks. The type of cough alone cannot tell you whether antibiotics are needed.
How are different causes considered?
With a cold, a cough is often accompanied by a runny nose, sore throat or fever. It can linger after other symptoms of a viral illness have resolved.
A nighttime cough, wheezing or symptoms triggered by exercise may warrant assessment for asthma. Heartburn or acid regurgitation can occur with reflux, but these symptoms alone do not establish the diagnosis.
What should you tell the doctor?
Explain when the cough started, how it has changed, and whether you have a fever, breathlessness, chest pain or contact with people who are ill. Mention smoking, allergies, regular medicines and treatments already tried.
The clinician decides whether blood tests, a chest X-ray or breathing-function tests are appropriate. Investigations are ordered based on the clinical findings rather than routinely for everyone.
Treatment depends on the cause
For an uncomplicated viral illness, rest, adequate fluids and symptom monitoring can be useful. Antibiotics do not treat an ordinary viral cough. Taking cough suppressants or inhaled medicines without advice may carry risks.
A cough that worsens, persists or repeatedly returns may require a revised diagnosis and investigation plan rather than continued use of the same medicine.
Describing your cough before the appointment
A brief diary can help: date of onset, daytime or nighttime symptoms, temperature, breathlessness and links with exercise or body position. Report changes in mucus if present, but sputum color alone does not determine whether antibiotics are needed.
Tell the clinician about recent infections, exposure to airborne irritants, smoking, allergies and current medicines. Certain medications can themselves contribute to a cough. A clear history helps select targeted tests and avoid unnecessary investigations.
Other useful topics include heartburn and gastroesophageal reflux disease (GERD).
Signs and symptoms
Dry or productive cough, throat irritation, mucus, nighttime worsening and sometimes fever. Breathlessness, coughing up blood or chest pain are separate warning signs.
Diagnosis and tests
The clinician takes a history and examines breathing, temperature and associated symptoms. Laboratory tests, imaging or specialist assessment are arranged when clinically indicated.
Care and treatment approaches
Management depends on the cause. Antibiotics are generally unnecessary for a viral infection, while asthma, pneumonia and other conditions require different treatment.
When to seek urgent care
Call 103 immediately if the person is struggling to breathe, has severe chest pain, blue lips, altered consciousness or a cough with substantial bleeding.
Frequently asked questions
Does every cough need antibiotics?
No. Many coughs are caused by viral infections, which antibiotics do not treat. The decision depends on examination and diagnosis.
When should I see a doctor?
When the cough becomes much worse, occurs with breathlessness or fever, or lasts longer than expected after an infection.
Is a chest X-ray always necessary?
No. The need for imaging depends on the symptoms, examination and suspected cause.
Important information
A medical consultation is needed for diagnosis and treatment recommendations.
Self-treatment can be harmful to your health.
