Allergic Rhinitis

The main cause of allergic rhinitis is due to the inhalation of allergens that triggers an inflammatory reaction in the nasal cavity. The symptoms are very similar to common colds such as, sneezing, runny nose, nasal congestion and itching, etc., and will last for a period of time. Most patients who suffer from allergic rhinitis also tend to suffer from allergic conjunctivitis, with symptoms such as itching, redness, watery eyes, and swollen eyes. The first priority is to avoid any exposure to allergens. Some allergens can be avoided, such as animal dander from house pets and house dust mites. The second type of nasal allergy drugs are antihistamines. Histamine will trigger mucosa swelling, increased secretions, nasal congestion, itching and allergic reactions such as sneezing, hence, the use of Antihistamines can reduce the symptoms of itching, sneezing and runny nose.
