Seasonal allergic rhinitis is an allergy to some plant pollen. It is particularly common during the spring due to the spread of pollen.

Symptoms of hay fever include runny nose, itchy skin, increased tear production, and sneezing attacks. Hay fever can be treated with medications that relieve symptoms. As a radical solution to hay fever, specific immunotherapy can be used. This is where the patient is injected with the allergen that has been identified, to gradually accustom the immune system to it.
