Chronic cough: GP-approved management tips

Overview

A chronic cough is defined as one that continues for eight weeks or more. It is prevalent in Australia and is frequently associated with conditions like asthma, gastroesophageal reflux, or allergies. While it can be quite bothersome, most underlying causes can be effectively managed with appropriate management.

What is a chronic cough?

A chronic cough persists for over eight weeks and differs from temporary coughs that result from viral infections. Unlike acute or subacute coughs, it typically indicates an underlying issue that requires evaluation. Cough is a normal protective reflex that expels unwanted materials from the respiratory tract. Most coughs are short-lived, not serious, and resolve fully in a week or two. However, cough sometimes can be a sign of serious underlying respiratory tract disease.

Types of coughs

Coughs are generally classified based on their duration and underlying causes, as outlined below:

Types of cough	Duration	Common causes
Acute	< 3 weeks	Colds, flu, viral infections
Subacute	3–8 weeks	Post-viral cough
Chronic	> 8 weeks	Asthma, reflux, post-nasal drip, smoking, medications

Wet cough and dry cough: What could cause it?

Coughs are classified as wet (productive) or dry (non-productive), and the reasons are different for each kind. Knowing whether a cough is wet or dry can help determine the best course of action for management and management by pointing to the underlying source of the problem.

Wet (productive) cough:

Usually linked to respiratory illnesses such as the common cold, flu, bronchitis, or pneumonia, these infections cause increased mucous formation in the airways, which the body attempts to eliminate through coughing. Other reasons include chronic illnesses such as chronic obstructive pulmonary disease (COPD) or bronchiectasis, which are characterised by mucus accumulation.

Dry (non-productive) cough:

This kind of cough is typically caused by irritation or inflammation in the throat and upper airways. Common reasons include viral infections (in the early stages), allergies, asthma, acid reflux, medications (particularly ACE inhibitors), and environmental factors such as smoking or pollution. Dry coughs can also be triggered by psychological causes like stress or worry.

Causes of a chronic cough

A chronic cough is usually linked to one or more underlying conditions, including:

• Asthma – inflammation of the airways that leads to coughing, wheezing, or sensations of tightness.
• Post-nasal drip – mucus flowing down the throat, leading to irritation.
• Gastro-oesophageal reflux (GORD) – irritation of the throat from stomach acid, particularly at nighttime.
• Smoking or vaping – irritants that can result in ongoing coughing.
• Chronic lung diseases (such as COPD) – more frequently seen in individuals who smoke long-term.
• Environmental irritants – bushfire smoke, dust, mould, and air pollution.
• Medications – ACE inhibitors (commonly prescribed for hypertension) can trigger a dry cough.
• Post-infection cough – often occurs after infections such as COVID-19, the flu, or other respiratory viruses.
• Whooping cough (pertussis) – during outbreaks, pertussis can cause intense, prolonged coughing episodes that may last for weeks.

Symptoms

A persistent cough is often accompanied by other symptoms, depending on the underlying cause.

• Wheezing
• Shortness of breath
• Chest tightness
• Hoarse voice
• Heartburn (if related to GORD)
• Nasal congestion or postnasal drip
• Cough that worsens at night

When a chronic cough needs urgent care

You should obtain immediate medical attention if you experience:

• Coughing up blood
• Unexplained weight loss
• Fever or excessive night sweating
• Chest discomfort
• Difficulty breathing
• A consistently hoarse voice
• A history of smoking coupled with an increasing cough

Note: If you are experiencing severe difficulty breathing or are coughing up significant amounts of blood, call 000 immediately or visit your nearest Emergency Department.

When to see a GP

You should seek medical advice promptly if you experience any of the following symptoms.

• Cough lasting more than 8 weeks
• Cough accompanied by fever or chest pain
• Coughing up blood
• Shortness of breath
• Unexplained weight loss
• Night sweats
• If you are pregnant or immunocompromised
• Persistent cough in children under 5 years

Diagnosed

Diagnosis is guided by the duration of the cough, associated symptoms, and potential triggers. Your GP may suggest a range of investigations to help identify the underlying cause.

• Chest X-ray or advanced imaging
• Spirometry (for asthma)
• Allergy testing
• Respiratory swabs (for COVID-19, RSV, or flu)
• Full blood count
• Evaluation for reflux
• Review of smoking or vaping history
• Review of current medications

In short, diagnosis depends on the combination of symptoms, cough duration, and potential triggers.

GP-approved management tips

Handling triggers at home

Simple lifestyle adjustments can help reduce cough triggers at home:

• Stay away from smoke, dust, and intense fragrances
• Utilise a humidifier if the atmosphere is dry
• Maintain good hydration
• Honey to alleviate throat irritation (not suitable for children under one year)

Addressing issues based on the underlying cause

Management strategies may vary depending on the cause of your chronic cough:

• Asthma: Adhere to your asthma action plan and check the usage of your inhaler
• Allergies/post-nasal drip: Consider antihistamines, saline rinses, and nasal sprays
• Reflux: Eat earlier, avoid spicy or acidic foods, and raise the head of your bed
• Dry cough: Consume warm liquids, use lozenges, and maintain humidity levels
• Smoker's cough: Look for support for quitting smoking (such as Quitline)

Over-the-counter solutions

Some over-the-counter options may provide short-term relief. Always seek advice before starting new management.

• Cough suppressants (only for short-term use)
• Saline nasal sprays
• Antacids (if related to reflux)

Consult with a pharmacist or online GP before initiating any new management.

When a GP might recommend medication

In some cases, a GP may recommend prescription management options such as:

• Asthma inhalers
• Nasal corticosteroids
• Proton pump inhibitors (for reflux)
• Antibiotics (only if a bacterial infection is suspected)
• Changing ACE inhibitors if they are contributing to the cough

Chronic cough among children

A continuous cough in children should be evaluated by a GP, particularly if it persists beyond four weeks. Over-the-counter cough syrups are generally not recommended for children and may be unsafe. In children, a persistent cough often follows a viral illness, but it may also be linked to asthma, allergies, or conditions such as pertussis. If a child's cough continues or is associated with difficulty breathing, feeding, or sleeping, or if there is a history of choking, a medical review is important. Early diagnosis is especially crucial in young children. Yes, online doctors can provide helpful support for coughing through virtual consultations. They can analyse symptoms, and medical history and correlate factors to identify potential causes of the cough. According to their evaluation, they may suggest appropriate management, and lifestyle changes, or prescribe medications if necessary. They may also recommend in-person visits or diagnostic tests to exclude significant underlying concerns. Online consultations offer ease of access, convenience, and professional medical guidance, ensuring timely care from coughing. If you are coughing constantly and seeking medical advice, there's no need to leave your couch or wait in clinics. Speak to a registered online GP within few minutes through a telehealth appointment. Note: While many aspects of a chronic cough can be managed via telehealth, a physical examination or in-person diagnostic test (such as listening to your lungs) may be required for an accurate diagnosis.

Conclusion

A chronic cough can be uncomfortable, frustrating, and disruptive, but most causes are treatable once properly identified. Paying attention to triggers, managing underlying conditions, and seeking timely GP advice can make a significant difference. With the right care, long-lasting coughs usually improve and become much easier to manage. While coughing is an innate and favourable reflex, prolonged or unusual coughing requires attention and assessment. Understanding the different causes and types of coughs can help in prompt identification and suitable care. Whether it is a momentary reaction to an irritant or a manifestation of a more severe problem, treating the root cause of coughing is crucial for supporting respiratory health and general wellness.
