Azelastine

What is Azelastine?

Azelastine is an antihistamine medication used to treat allergy symptoms affecting the nose and eyes. It belongs to the second generation antihistamine drug class, which works by blocking histamine, a chemical released during allergic reactions.

It is commonly prescribed for:

• Seasonal allergic rhinitis hay fever

• Allergic conjunctivitis eye allergies

What is the Recommended Dosage of Azelastine?

Dosage varies based on:

• Severity of symptoms
• Response to therapy

Patients should:

• Use the medication exactly as prescribed
• Follow device instructions carefully
• Avoid exceeding recommended frequency

Dosing must be guided by an allergist, ENT specialist, ophthalmologist, or primary care physician. Do not change dosing without medical advice.

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.

Patients should:

• Consult a licensed allergist, ENT specialist, or ophthalmologist
