Use of Azelastine in patients where oral antihistamines fail

Even in those patients who do not respond to the treatment of established orally taken antihistamines Azelastine nasal spray does still show an improvement in relief of symptoms with a long lasting effect for hours. This is thanks both to the way in which the substance is applied - directly to the nasal mucous membrane - and to its high degree of effectiveness. Azelastine is a very effective rescue medication in patients who do not respond to oral antihistamines and a good choice for treating allergy.
