Astelin for Allergies

Astelin® (azelastine hydrochloride) is a medication approved to treat sneezing, a runny or stuffy nose, and nasal itching (known medically as rhinitis). This prescription medication is approved to treat these symptoms when they are due to either seasonal allergens (known as seasonal allergic rhinitis) or to other irritants (known as rhinitis or vasomotor rhinitis).
Allergies occur when the body's immune system reacts to a normally harmless substance -- one that does not bother most people. This reaction is partly caused by the release of histamine from certain cells, known as mast cells. Astelin is an antihistamine nasal spray that acts in at least two different ways. It helps prevent the release of histamine from mast cells, and if any histamine is released, Astelin prevents it from binding to histamine receptors. Because histamine is responsible for many of the symptoms of allergies, blocking it can be helpful.
Astelin comes in the form of a nasal spray and is typically taken twice a day. It comes in one strength -- Astelin nasal spray, containing 200 sprays in each bottle, with 137 mcg of medication in each spray. Studies have shown that Astelin begins working within 3 hours and lasts at least 12 hours.
