Allergy symptoms kick in when your immune system overreacts to substances called allergens. Indoor allergens, including mold, dust, and pet dander can cause allergy symptoms at home and at work. Since indoor allergies can be triggered any time of year, they can often be easily confused with a cold. Understanding and recognizing the symptoms is half the battle. Outdoor pollen from the spring, summer, and fall can be present inside your home too. Speak to your doctor or pharmacist. To be sure this product is right for you, always read and follow the label.
