Allergic rhinitis is a medical condition that affects a great number of people, both adults and children. Its symptoms are usually torturous and may occur in the form of runny or stuffy nose, difficulty in breeding, watery eyes, sneezing, or headache. The most common season for the symptoms to manifest is spring, due to the intense flowering in urban centers as well as in the country. But when allergy is due to factors that can affect throughout the year (e.g. mites) then symptoms of allergic rhinitis may last during the whole year. This way, the correct diagnosis of the specific allergic agent and its identification is of primary importance for planning the treatment of the causes for allergic rhinitis, which is custom-made for each patient.
