If symptoms are severe, treatment of hay fever is aimed at making you more comfortable and allowing you to function better in your daily life. Medications such as antihistamines, decongestants, and steroid nasal sprays are available, although most people do not require medication. If symptoms persist, you may want to consider having more allergy tests.
There is no known way to prevent allergies, though some researchers believe that breast-fed babies are less likely to develop allergies. Allergies last different amounts of time for everyone. Some people suffer from allergies for their entire lives while others develop them only during childhood or adulthood. Allergies may stop if you move to an area free of the substances causing your allergies.
