Successful treatment with allergy shots

Successful treatment with allergy relief shots generally requires three to five years of regular injections. But, allergy relief shots can provide relief from symptoms that may continue after treatment is complete. Allergy relief shots may offer the best relief if you have persistent allergies that don't respond.
Pollen allergy affects about 1 out of 10 Americans, according to the National Institute of Allergy and Infectious Diseases (NIAID). For some, symptoms can be controlled by using over-the-counter medicines. Some molds, another allergy trigger, may also be seasonal. For example, leaf mold is more common in the fall. FDA regulates medications that offer allergy relief.
