What to do with a lingering cough

If you’ve ever had a cough that lingers after a cold or respiratory infection, you’re not alone.
Post-viral cough affects nearly 40% of adults and is one of the most common reasons patients seek care after an illness. It can be frustrating, disruptive to sleep and work, and understandably concerning.
The good news is that in most cases, post-viral cough is not dangerous and is self-limited.
How long does post-viral cough last?
Most people seek medical attention if their cough has been ongoing for 2-3 weeks. Fortunately, symptoms typically improve on their own within another 2–3 weeks, depending on the virus involved.
Understanding what helps—and what doesn’t—can save you unnecessary medications, side effects, and worry.
Why common cough medicines often fall short
Despite being widely used, many medications commonly taken for post-viral cough show little to no consistent benefit in clinical studies.
These include:
Over-the-counter cough suppressants and expectorants
Antihistamine/decongestant combinations
Anti-inflammatory medications such as ibuprofen or naproxen
Prescription opioid cough medications
Steroids (prednisone), which are often prescribed despite limited evidence
Because post-viral cough usually resolves on its own, national chest medicine guidelines recommend against routine medication treatment. In addition to limited effectiveness, many of these medications carry side effects such as drowsiness, dizziness, gastrointestinal upset, mood changes, or sleep disturbances.
What actually helps with post-viral cough
Supportive, targeted care tends to be more effective and much safer for most patients.
Helpful strategies may include:
1. Supportive symptom relief
Honey can provide modest cough relief and is generally well tolerated (not recommended for children under 1 year).
Staying well hydrated and avoiding airway irritants like smoke or strong fragrances.
2. Upper airway care
Nasal saline irrigation can reduce irritation and post-nasal drip that often trigger coughing.
Certain specialized nasal sprays may help shorten symptom duration or reduce severity for some patients.
3. Addressing underlying triggers
Post-viral cough is often worsened by factors such as:
Post-nasal drip
Nasal inflammation
Acid reflux
Addressing these contributors—rather than suppressing the cough itself—can significantly improve symptoms.
When should you see your doctor?
While most post-viral coughs are harmless, medical evaluation is important if you have:
Cough lasting longer than 6–8 weeks
Fever, shortness of breath, or chest pain
Coughing up blood
Worsening symptoms instead of gradual improvement
Underlying lung or immune conditions
