Allergic Rhinitis and Mast Cell Inhibitors
Mast cell inhibitors for allergic rhinitis come in the form of nasal sprays that have anti-histamine effects. Intal (cromolyn sodium) is an example of a mast cell inhibitor, and it is unique because it can be used to prevent symptoms from developing.
Cromolyn changes the body's immunological response to allergens, possibly preventing the symptoms of allergic rhinitis.
Cromolyn is most effective when used before coming into contact with substances that cause allergies or before allergy season. It may be used alone or with other medicines.
