According to Berger, author of Allergies and Asthma for Dummies,the best way to treat nasal allergies is with prevention.
First, get a skin test to find out which allergens -- such as dust, pollen, mold, and pet dander -- are triggering your allergic reaction. Try to clear those allergens out of your indoor environment, and away from your yard as much as possible.
If you still have symptoms, it's time to turn to allergy medicines.
Berger explains that the first line of allergy treatment is inhaled nasal corticosteroids. Inhaled nasal steroids decrease inflammation and reduce mucus formation, so you have fewer allergy symptoms.
"You need to start about two weeks before pollen season with the inhaled nasal corticosteroids," Berger explains, "and possibly stay on the inhaled allergy medicine for months, if you have ongoing nasal allergies."
