Bronchitis in Adults: Symptoms, Treatment and Recovery

What are the symptoms of bronchitis?

Cough is the main symptom and may be dry or bring up mucus. A sore throat, tiredness, blocked or runny nose and mild aches may accompany the illness. Coughing can make the chest muscles uncomfortable. The symptoms often begin with a respiratory infection. [1], [2]

Neither the sound of a cough nor the color of the mucus can establish the diagnosis. Yellow or green sputum does not, by itself, show that antibiotics are needed. Read our guide to coughing up mucus for other causes and warning signs. [3]

How long does a bronchitis cough last?

NICE advises that an acute cough can take three to four weeks to settle. Improvement is usually gradual: you may feel better before the cough disappears. A cough lasting several days is therefore not, on its own, evidence that treatment has failed. [4]

Arrange review if the cough has lasted more than three weeks without improvement, returns repeatedly, or is getting worse. Seek help sooner for warning signs. Our persistent cough guide explains why a longer-lasting cough needs a broader assessment. [2]

Acute bronchitis, pneumonia and chronic bronchitis

An infection can also trigger an asthma or COPD flare-up. Someone with established lung disease should follow their action plan and seek advice about a change from their usual breathing. The guidance for an otherwise healthy adult with uncomplicated bronchitis may not fit that situation. See our COPD assessment service or asthma service.

A persistent cough with weight loss, night sweats, fever or a history of TB exposure needs assessment for tuberculosis and other causes. It should not simply be treated repeatedly as bronchitis. [6]

How is bronchitis diagnosed?

The doctor asks about the illness, examines the chest and checks observations such as temperature, breathing rate and oxygen saturation when appropriate. The first task is to identify pneumonia or another explanation for the symptoms. [3]

An otherwise healthy adult with a typical illness and reassuring findings often does not need a chest X-ray. Imaging or other tests may be appropriate when the examination, risk factors or course of the illness raises concern. No single home reading can replace that assessment. [3]

Bring a medication list and describe when the cough began, whether it is improving, any fever, blood in sputum, smoking or vaping, and any previous asthma or COPD. If episodes keep recurring, the clinician may plan further investigation after the acute illness.

What helps, and when are antibiotics appropriate?

For uncomplicated acute bronchitis, care usually focuses on comfort while the illness resolves. Rest, suitable fluids and a warm drink may help. Honey can soothe a cough in adults; it must never be given to infants under one year. Ask a pharmacist or clinician which pain or fever medicine is suitable for you. [1], [2]

Do not automatically start an antibiotic, steroid course or someone else’s inhaler. NICE does not recommend routine antibiotics for patients who are not very unwell or at increased risk of complications. A clinician may prescribe them for selected higher-risk patients or when a different diagnosis, such as pneumonia or pertussis, is suspected. [1], [4]

Antibiotics can cause adverse effects and contribute to resistance. Cough medicines may offer limited symptom relief but do not reliably shorten the illness; combination products can duplicate ingredients. Review the label and your other medicines with a pharmacist. [1], [3]

Avoid tobacco smoke and other airway irritants. Cover coughs, clean hands and keep recommended vaccinations up to date. During poor air quality, reduce exposure and choose a cleaner indoor environment. Our Lahore smog guide explains practical exposure reduction. [1]

When should you seek urgent help?

Arrange prompt medical review for coughing up blood, chest pain, persistent or returning fever, new breathlessness or feeling too unwell for normal activities. Older adults, pregnant people and those with significant heart or lung disease or reduced immunity should seek advice earlier. [1], [2]
