An allergy triggers a reaction in an individual's immune system. The body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.


Allergy symptoms vary from one individual to the next ranging from mild to severe reactions. The most common environmental allergy symptoms may include one or more of the following:


  • Sneezing
  • Runny nose
  • Nasal congestion
  • Coughing
