Temporarily relieves allergy symptoms from hay fever or respiratory allergies such as sinus congestion, sneezing, nasal discharge, itchy or burning eyes, and headache.
Allergies are an abnormal response of the immune system. Not everyone has allergies. People inherit a tendency to be allergic, although not to any specific allergen. When one parent is allergic, their child has a 50% chance of having allergies. That risk jumps to 75% if both parents have allergies. People who have allergies have an immune system that reacts to a usually harmless substance in the environment. Allergies affect at least two out of every 10 Americans. Most environmental allergens contact the skin, eyes, or are inhaled. That's why, most symptoms affect the skin, eyes or the respiratory passages.
Risk factors for allergies can be placed in two general categories, personal and environmental.
Personal factors include:
• hereditary - the most significant
Four major environmental factors:
• changes in exposure to infectious diseases during early childhood
• environmental pollution
• allergen levels
• dietary changes
