INFORMATION FOR WOMEN WHO HAVE ALLERGIC RHINITIS DURING PREGNANCY OR BREASTFEEDING

 

What is allergic rhinitis?

Allergic rhinitis, also called hayfever, is a condition in which the inner lining of your nasal passage becomes inflamed. This is due to a sensitivity to allergens, which cause a response that is driven by a type of immunoglobulin (antibody) called IgE. The condition can be perennial (present throughout the year), episodic (happens in episodes due to the presence of an inhaled allergen, such as dust), or it can be seasonal, meaning that it happens at certain times of the year, due to an increase in certain out-door allergens, such as pollen. Other agents that cause allergic rhinitis are dust mites, molds, and pets.
