Overview

AZELASTINE NASAL SPRAY What is azelastine. Azelastine is an over-the-counter antihistamine nasal spray for seasonal or year-long allergy symptoms such as nasal congestion, a runny nose, sneezing, itching, and post-nasal drip. It can be given as one or two sprays in each nostril twice a day and is a suitable antihistamine option with fewer side effects compared to oral antihistamines.   How can azelastine help alleviate certain long COVID symptoms. Histamine is a chemical our immune system releases that causes our allergy symptoms. Cells in our body called mast cells release histamine, and in some patients after COVID, they may release too much, leading to some of the symptoms of long COVID.

How it works:

Blocks histamine type 1 receptors, reduces hyper-activity of nasal airways

Dosage Form: Tablet Nasal spray - 137mcg/spray, 205.5 mcg/spray

Common Usage: seasonal or year-long allergy symptoms such as stuffy or runny nose, itching, sneezing, post-nasal drip
