We don't get good freezes to hold down the molds, we have a long-growing season and, just when other things go dormant, cedar trees send out clouds of pollen. We just don't get a break. Every time you come in contact with an allergen, you put a little more histamine in the bucket. The winter break in cold climates allows you to empty the bucket, and it takes awhile to fill it up again. Knowing what allergens trigger your attacks, and avoiding them, is the first line of defense.
Testing is most useful for airborne allergies, such as pet dander, pollens and molds.
Immunotherapy is effective for about 75 percent of patients, reducing or eliminating symptoms for the identified allergens. It requires bi-weekly injections for several months and, depending on the person, monthly maintenance shots for several years. When you start allergy shots, plan on having a long-term relationship with your allergist. Wait until you expect to be in the same general area for awhile, and avoid changing insurance unless you know your allergist is on the new plan. For this reason, many allergists recommend waiting until after puberty to begin immunotherapy unless the child's symptoms are affecting his or her health.
