Your home, school or workplace may contain substances that can cause an allergic reaction. These environmental substances include dust or dust mites, animal dander (mostly cats), mold spores, mildew or pollen. While pollen allergies usually occur in certain seasons, these other substances can cause allergy problems all year round.
While avoidance is the best solution in most cases, some causes of symptoms, such as pollen, molds, and dust mites, cannot be eliminated. Exposure can be reduced, however, by environmental control measures prescribed by your allergist.
