Azelastine nasal spray
AllergyAlso known as Astepro
Azelastine is an antihistamine in spray form, so it goes straight to the source — the lining of your nose. It blocks histamine right where pollen and dust trigger it, which is why it works faster than steroid sprays like fluticasone, often within 15 to 30 minutes. Two honest heads-ups: it can leave a bitter taste in the back of your throat, and even though it's a spray, it can make some people drowsy.
How to take it
When
Use it as the label or your doctor directs — daily during allergy season works best, though it also relieves symptoms fairly quickly when they flare.
Food
Food doesn't matter. Tilting your head slightly down when you spray, and not sniffing hard afterward, helps keep the bitter taste out of your throat.
Avoid
Skip alcohol and be careful about driving until you know how it affects you — azelastine can cause drowsiness even as a nose spray.
How to use it
Blow your nose first, prime the pump if it's new or unused for a while, and aim the tip slightly outward, away from the middle wall of your nose, to prevent irritation and nosebleeds.
Missed a dose?
If you use it daily and miss a dose, use it when you remember. If it's nearly time for your next dose, just skip the missed one. Never double up.
