What is Azelastine?

How Azelastine Works

Azelastine blocks histamine receptors in the body. Histamine is responsible for many allergy symptoms.

By blocking histamine, Azelastine helps:

Reduce sneezing

Decrease nasal itching

Control runny nose

Relieve eye redness and itching

It may also have mild anti inflammatory effects.

The medication helps control symptoms but does not cure the underlying allergic condition. Continued exposure to allergens may still trigger symptoms.
