Rhinitis is an umbrella term for the inflammation of the nasal passages. 1 Symptoms of rhinitis are sneezing and a runny and/or itchy nose. 1

Rhinitis can be divided into allergic rhinitis and non-allergic rhinitis: 1


Allergic rhinitis: 1

  • This is an over reaction by the body’s immune system to allergens like pollen, mould, dust, or smoke
  • The immune system produces a chemical called histamine in response to allergens
  • Histamine causes sinus membranes to swell, resulting in congestion and sneezing

Non-allergic rhinitis: 1

  • This is not linked to an allergic reaction
  • Can be triggered by smoke and other pollutants, as well as strong smells, alcohol, or cold temperatures
  • It may also be caused by nasal blockages, infections, and overuse of some medications

Sinusitis (also known as rhinosinusitis) symptoms are similar to those of rhinitis. 1 Sinusitis very often occurs after rhinitis and involves the nasal passages and the blockage of parts of the sinus cavities. 2 The fluid produced in the sinuses and the blockage of the nasal passages can lead to bacterial infection and chronic sinusitis. 1

If you are still having problems determining whether you have allergic rhinitis or sinusitis, visit one of the Medicare Pharmacies for a Videomed consult with a doctor in pharmacy.

Allergic rhinitis and sinusitis can often seem like the same thing. Here is a table to help you compare your symptoms:
