Long lasting relief (dosing)
Azelastine has a long-acting effect with fast relief of symptoms. Unless otherwise specified by a doctor, one puff of Azelastine should be applied to each nostril twice daily (morning and evening).
The same applies to eye drops: trickle one drop in each eye twice daily (morning and evening). In case of severe symptoms, this dose can be increased to one drop per eye up to four times daily.
