ABOUT ALLERGIES
Nasal Allergies and You: About allergies
When you come into contact with an allergen, or a trigger, your body produces higher levels of certain types of substances. You may have heard of one type called histamine. Another type is called leukotrienes (loo-ko-TRY-eens). Leukotrienes play an important role in causing allergy symptoms.
These types of substances signal your body to respond to allergens with symptoms such as:
- Congestion
- Runny nose
- Sneezing
- Itchy nose
The medical term for these symptoms is allergic rhinitis. You probably know it better as hay fever or, simply, indoor and outdoor allergies.
Allergy symptoms can bother you when you are trying to:
- Enjoy outdoor activities, such as a spring fair, a summer picnic, or a fall hike
- Play outdoors
- Join in sports
- Get your work done
- Stay alert at school
- Get a good night's sleep
This allergy season, think about an allergy medicine that works differently by blocking leukotrienes.
