Cough
Cough is a protective reflex of the airways. Acute (< 3 weeks) is almost always due to a benign viral infection (cold, viral bronchitis). Subacute (3–8 weeks) may follow a resolving infection. Chronic (> 8 weeks) requires a workup with the doctor to rule out asthma, reflux, allergy, smoking, or a more serious cause.
Red flags
- Coughing up blood (haemoptysis)
- Shortness of breath at rest or while talking
- Acute chest pain
- High fever with chills
- Unexplained weight loss, night sweats
- Cough > 3 weeks in a smoker
Relieving a benign cough
Hydrate abundantly to thin secretions. A spoonful of honey at night (avoid in children < 1 year) effectively soothes the throat according to several clinical trials. Avoid cough syrups for productive cough: they prevent mucus clearance. Air your room and humidify if possible. Stopping smoking, even temporarily, significantly speeds recovery. Paracetamol relieves associated fever and aches.
When to consult
Book a consultation if the cough lasts > 3 weeks, with persistent fever, unusual fatigue or deterioration of general state. Auscultation and sometimes a chest X-ray help rule out pneumonia, asthma or other pathology. For smokers, any chronic cough deserves an opinion. At Maison Médicale Parc Astrid, your GP provides follow-up and refers to a pneumologist if needed.

Should I take antibiotics for a cough?
No. > 90% of acute coughs are viral and antibiotics are useless, even harmful (resistance, side effects).
Is night cough more concerning?
A cough that systematically wakes you at night can suggest asthma, gastro-oesophageal reflux or heart failure. Mention it to your doctor.
