What should I know before taking azelastine?

Azelastine can cause significant drowsiness, so do not drive, operate machinery or do any other activities that require you to be alert until you know how this medication affects you. Alcohol can also increase the drowsiness or dizziness caused by azelastine, so it is best not to drink alcoholic beverages while using this medication. If you regularly use other medications that cause drowsiness, you should talk to your doctor about whether to take azelastine hydrochloride, since these drugs can combine to cause severe and sudden drowsiness.
