Cough syncope treatment and safety steps

A clinician will ask about the cough, the position in which you fainted, warning symptoms, medicines, medical history and recovery. They may check blood pressure, heart rhythm and breathing, with further tests guided by the findings. Treatment is directed at the cause of the cough rather than at the blackout alone.

Low fluid levels, low blood glucose, anaemia and an irregular rhythm can all change how the body responds to a forceful cough. Information on [Dehydration](/conditions/dehydration/), [Hypoglycaemia](/conditions/hypoglycaemia/), [Anaemia](/conditions/anaemia/) and [Atrial Fibrillation](/conditions/atrial-fibrillation/) may help you prepare for the discussion.

At the first hint of light-headedness, stop and lie down somewhere safe. Avoid driving, heights, water activities alone and machinery until you have received individual advice. Keep a record of coughing spells, fainting, injuries, palpitations and new medicines. Follow the treatment prescribed for the cough; do not start antibiotics or sedating cough medicines without advice, because the right option depends on the cause and your health.

Call emergency services for fainting with chest pain, severe breathing difficulty, a serious head injury, blue or grey lips, prolonged confusion, seizure-like movements or a heartbeat that remains very fast or irregular. Arrange prompt medical review after any first faint, repeated episode, blackout without a cough, or episode occurring during exertion. A cough-related explanation should not delay assessment of these signs.

What is the likely cough trigger, and how will we treat it? Could any of my medicines worsen fainting? Should I have heart-rhythm or blood tests? When can I safely drive or return to exercise?
