What are year-round allergies?

An allergy is when your body's immune system reacts to something harmless, such as food, plants, or medicine. The substance that causes the allergic reaction is called an allergen.

Year-round allergies are:

  • Allergies that happen throughout the year

These allergies can happen at any time of year or all year long. They don't happen just in one season, like seasonal allergies.

  • Year-round allergies are your body’s reaction to substances in the air, most commonly house dust

  • Usually they cause a stuffy, runny, or itchy nose, an itchy throat, or red and itchy eyes

  • Avoiding the allergen is best, but medicine can help with your symptoms
