What is post-nasal drip?

‘Post-nasal drip’ is when mucus from your nose or sinuses drips down the back of your throat.

Post-nasal drip can sometimes cause a cough.

What causes post-nasal drip?

The most common causes of post-nasal drip are:

  • viral infections in your nose and throat (such as a cold)
  • hay fever — inflammation of the inside lining of your nose, also called ‘allergic rhinitis’
  • sinusitis —inflammation of the hollow spaces in the bones of your face (sinuses)
  • cold air
  • some medicines

Other causes are asthma and gastro-oesophageal reflux disease (GORD).

Rarely, post-nasal drip can be a sign of a foreign object in the nose (usually in children).

What are the symptoms of post-nasal drip?

Symptoms of post-nasal drip include:

  • blocked or runny nose
  • a cough
  • a ‘tickle’ in your throat or a sore throat
  • needing to clear your throat regularly
  • a lot of mucus in your throat
  • a hoarse voice

People with post-nasal drip can also get bad breath.

How can I treat post-nasal drip?

The treatment for post-nasal drip depends on its cause.

If your post-nasal drip is caused by hay fever, then antihistamines, decongestant medicines and steroid nasal sprays can help relieve your symptoms. A saline nasal spray can also help.

You can prevent hay fever by avoiding substances you are allergic to. If you don’t know what you are allergic to, speak with your doctor who can refer you for allergy tests.

If your post-nasal drip is caused by sinusitis from a bacterial infection, your doctor might prescribe antibiotics to treat the infection.

If your post-nasal drip is caused by reflux or asthma, you should talk with your doctor about treatment.

Sinusitis and allergy - Australasian Society of Clinical Immunology and Allergy (ASCIA)

The sinuses are cavities within the skull. They drain into the nose through small holes. Sinusitis means inflammation of the nasal sinuses. Sinusitis is most commonly short-lived, such as after a viral cold. Blockage of the drainage pathways, however, creates an environment that favours the overgrowth of bacteria resulting in long-term (chronic) sinusitis. Hayfever and polyps are the most common reasons for having recurrent or chronic sinus infection.
