Prevention & Expectations
What can be done to prevent the condition?
Many allergens are present in the air, so it may be very difficult for some people to prevent nasal allergies.
Antihistamines, such as diphenhydramine or chlorpheniramine, can block the symptoms. Nasal steroid sprays, such as cromolyn, help to stop mast cells from releasing their substances. Nasal steroids stop the mast cell from discharging and thus prevent early symptoms.
What are the long-term effects of the condition?
Most of the long-term effects occur in those who have prolonged or frequent periods of allergic disease. The presence of allergic rhinitis increases the risk of asthma four times. People with chronic allergies, such as those who are sensitive to dust, are more likely to develop chronic long-term symptoms.
Individuals who have allergic disease for long periods, such as spring through fall, may also develop long-term symptoms. These long-term symptoms include:
Nasal allergies can predispose an individual to sinus infections and asthma. Lost productivity costing billions of dollars per year occurs because of allergic disease.
