What to tell us about your symptoms

Acute bronchitis commonly causes a cough, sometimes with mucus. A cough can also come from other conditions; its cause cannot be settled just by how it sounds.

What the video visit can help with

Tell us how long you have been coughing, what makes it worse and whether you have fever, chest discomfort or breathing problems. Mention smoking, asthma and other lung conditions as part of the history.

When an examination or testing may be needed

Listening to the lungs, checking oxygen levels or arranging other tests may require in-person care. The clinician can explain when those steps matter rather than treat every persistent cough as bronchitis.

Discussing treatment

Most acute bronchitis is caused by a virus, so antibiotics usually do not help. For concerns suitable for video, the clinician can discuss symptom management and whether a different evaluation is needed.

When to get care in person

Trouble breathing, coughing up blood or feeling seriously unwell calls for prompt medical assessment. Severe breathing difficulty or chest pain needs emergency care.

Before your visit

Note when the cough began and what you have taken for it. Include inhalers and over-the-counter combination products so the clinician understands the full picture.

Questions about this care

Does a chest cold need an antibiotic?

Usually not when it is ordinary acute bronchitis caused by a virus. The important question is whether your symptoms fit that pattern or need another assessment.
