Good allergy treatment is based on your medical history, what type of allergy you have, and if your symptoms are mild or severe.
Antihistamines relieve sneezing and itching in the nose and eyes. They also reduce a runny nose and, to a lesser extent, nasal stuffiness. ( Ex: Clarinex )
Corticosteroid nasal (nose) sprays These types of nasal sprays reduce inflammation (swelling) in the nose and block allergic reactions from developing. They are the most effective medicine type for allergic rhinitis (nose allergy symptoms) because they can reduce all nasal symptoms, including congestion (stuffiness).
An allergic reaction occurs when the body’s immune system identifies a typically harmless substance, such as pollen, dust, or animal fur, and overreacts to it. The substance it reacts to is known as an allergen.
When an allergic reaction occurs, allergens bind to antibodies that the body produces called immunoglobin E (IgE). Antibodies combat foreign and potentially harmful substances in the body.
Once the allergen binds to IgE, specific types of cells — including mast cells — will release chemicals that trigger the symptoms of the allergic reaction.
Histamine is one of these chemicals. It causes the muscles in the airways and walls of the blood vessels to tighten. It also instructs the lining of the nose to produce more mucus.
