When allergic reactions affect the eyes, nose, and throat, the symptoms are often categorized as rhinitis. Allergic rhinitis is an extremely common illness that is often mistaken for an ordinary cold. However, rhinitis may develop into more severe problems such as asthma. It is common to over diagnose allergic rhinitis. Studies have shown that approximately 65% of patients diagnosed as having allergic rhinitis and prescribed antihistamines were actually not allergic. That is why recurring or drawn-out symptoms should always be investigated.
Rhinitis occurs when airborne allergens start an inflammation that triggers fluid production in the nose, sinuses, and in the eyes. Rhinitis is often seasonal, occurring during pollen seasons, but it can also be perennial, and persistent throughout the year.
