  • Smoking – the main cause of chronic cough
  • Asthma – the second common cause of cough
  • Acid reflux – gastroesophageal reflux disease (GERD) arises once the stomach acid flows back into the esophagus with symptoms such as chest pain, heartburn, shortness of breath and wheezing. The irritation triggered by these symptoms can result to chronic cough.

  • Allergies
    Oftentimes, the cough itself is the only indication of chronic cough.

Indications of chronic cough

Oftentimes, the cough itself is the only indication of chronic cough.

Other symptoms that might be present include:

  • Stuffed or runny nose
  • Shortness of breath or wheezing
  • Postnasal drip
  • Coughing up blood or phlegm
  • Weight loss without any effort
  • Throat pain
  • Heartburn
  • Fever, usually higher than 101 degrees F
  • Excessive sweating
  • Frequent clearing of the throat


The treatment for chronic cough is based on the exact cause:

  • If due to asthma, inhaled bronchodilators and/or steroids are given which reduce airway inflammation and wheezing.
  • If brought about by GERD, various non-drug treatments and prescription medications might be used. The non-drug measures include elevating the head using pillows while lying down, avoidance of foods that trigger acid reflux and avoid eating before bedtime. The prescription medications such as esomeprazole, omeprazole and cimetidine are given to lower the stomach acid.
  • If bacterial pneumonia or bronchitis is the cause, antibiotics such as azithromycin or cefuroxime are prescribed.
  • If the cause is postnasal drip, over-the-counter decongestants such as pseudoephedrine or diphenhydramine can be given to relieve the postnasal drip symptoms. If the cause is sinusitis, antibiotics might be given.
  • If the cause is using specific high blood pressure medications, other high blood pressure medications might be prescribed.
  • In case other treatments fail to work and chronic cough is severe, a cough suppressant such as codeine might be given.
