Allergic rhinitis is generally caused by exposure to allergens.

Clinically, the most common allergens are mainly pollen and dust mites.

Once the condition flares up, symptoms such as repeated sneezing, itchy nose, runny nose, and nasal congestion may occur.

During the spring when flowers are in bloom, it is advisable to wear a mask.

If the condition often flares up in a particular season, preventive medications can usually be used in advance, such as Flonase nasal spray and Montelukast sodium.
