Allergic rhinitis (commonly called hay fever) is an inflammation or irritation of the mucous membranes that form the inner lining of the nose. Common typical symptoms include sneezing and runny nose(watery rhinorrhea). Other symptoms include a stuffy nose, itchy eyes or nose, watery eyes.
Allergic rhinitis happens when an allergen (mainly house dust mite) causes your body to defend itself by producing antibodies. Allergic rhinitis is very hard to be treated.
Nasilen would be very good choice for this condition. In most cases the effect is not
temporary, it is radical.
