A mixture of the allergens identified from your allergy tests is prepared. You then receive weekly injections of this mixture. However, you will probably need to continue the shots for 2 to 3 years or longer. Proper treatment of allergy symptoms is the best way to prevent complications of allergic rhinitis, such as ear and sinus infections. If childhood allergies persist into adulthood, they will likely be present for a lifetime.
New allergies can develop any time, even in previously nonallergic persons.
Allergy symptoms are dependent not only on season and weather but also on location. Hence, your allergies may wax and wane, depending on where you are living. There are no known ways to prevent the development of allergic rhinitis. Once allergies have developed, you can try to limit exposure to the things that cause them, for example, pollens or animals. In severe cases, you may need to move to another area, but you may develop allergies there as well.
