A cough is termed "chronic", which means persisting, if it has hung around for more than eight weeks. A shorter-term cough, lasting up to three weeks, is called "acute", and if it is somewhere in the middle, it's called "subacute". Infections (such as the common cold or a chest infection) are the most common reason for acute coughs, but these usually settle within about three weeks.

If you have had a cough which is not settling after three weeks then always see your doctor. Particularly see your doctor if you have a cough along with:

  • Weight loss
  • Chest pain
  • Breathing problems
  • Sweats.

This will depend on the cause. Smoking irritates the airways and is one of the biggest causes of cough. If it isn't causing the cough, it certainly won't be helping it. So if you smoke, please consider quitting.

Other than that, the treatment will be specific to the cause. For example, inhalers may be prescribed for asthma, antacid medicines may be prescribed for reflux, nasal sprays may be prescribed for catarrh coming from the nose.
