Do I need to prepare the dispenser before I can use Astelin?

Yes, the first time you use a bottle of Astelin (azelastine) spray you need to prepare the bottle. This involves taking off the cap and replacing it with the pump that comes with it. Before using it, you should spray it several times until a mist appears. If you do not use the spray for several days, you should spray it again several times before using it.
