Question 1

What is Azelastine?

Accepted Answer

Azelastine is a medication that belongs to the antihistamine class of drugs. It works by inhibiting the activity of histamine, a chemical messenger released by the immune system during a hypersensitivity response.

By blocking these histamine receptors, the medication prevents the chemical from triggering common physical reactions.

Question 2

What is Azelastine used for?

Accepted Answer

Azelastine is used to treat allergic rhinitis and vasomotor rhinitis .

Question 3

How does Azelastine work?

Accepted Answer

Mechanism of Action

Azelastine belongs to a class of medications known as antihistamines. It works by competing with histamine for H1-receptor sites in the body. Histamine is a chemical released by the immune system when it encounters an allergen, such as pollen, mold, or pet dander. When histamine attaches to receptors in the nose or eyes, it triggers the physical symptoms of an allergic reaction.

By blocking these receptors, azelastine prevents histamine from binding to them. This interference helps to reduce or stop the following symptoms:

Sneezing

Itching of the nose or eyes

Runny nose and post-nasal drip

Redness and watering of the eyes

Targeted Relief

Azelastine is typically applied directly to the area affected by allergies, such as the nasal passages or the surface of the eye. This localized application allows the medication to work where it is needed most. In the nose, it helps decrease the swelling of nasal membranes and reduces mucus production. When used in the eyes, it helps stabilize the cells to prevent the further release of inflammatory substances that cause itching and redness.

Unlike some older antihistamines taken by mouth, azelastine applied locally can provide rapid relief of symptoms by acting directly on the tissues exposed to allergens.

Question 8

What is the dosage of Azelastine and how do I take it?

Accepted Answer

General Instructions

Azelastine is intended for use in the nose only. It should not be sprayed into the eyes or mouth. Before using a new bottle for the first time, the pump must be primed by spraying it into the air until a fine mist is released. If the medication has not been used for several days, it may need to be primed again.

How to Administer

To use the nasal spray, follow these steps:

Gently blow your nose to clear your nostrils.

Keep your head tilted slightly forward.

Insert the tip of the spray bottle into one nostril, pointing it toward the outer side of the nose and away from the center wall.

Close the other nostril with your finger.

Breathe in gently through the nose while activating the spray.

Repeat the process in the other nostril if instructed by a healthcare provider.

Avoid tilting your head back immediately after use to prevent the medicine from draining into the throat.

After use, wipe the tip of the bottle with a clean tissue and replace the protective cap.

Missed Dose

If you miss a dose, use it as soon as you remember. However, if it is nearly time for your next dose, skip the missed application and return to your regular schedule. Do not use double the amount of medication to make up for a missed dose.

Question 9

Is Azelastine safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There are no adequate and well-controlled studies on the use of azelastine in pregnant women. In animal studies, very high doses of the medication—significantly higher than the standard human dose—were associated with developmental issues, including skeletal abnormalities and lower birth weight. Because animal research does not always predict how a drug will affect humans, azelastine should be used during pregnancy only if a healthcare provider determines that the potential benefit justifies the potential risk to the fetus.

Breastfeeding

It is currently unknown whether azelastine is excreted in human breast milk. Because many medications can pass into milk and potentially affect a nursing infant, caution is advised. Individuals who are breastfeeding or planning to breastfeed should consult with their healthcare provider to discuss the risks and benefits of using azelastine.

Question 10

What forms and strengths does Azelastine come in?

Accepted Answer

Nasal Spray

Azelastine is commonly provided as a metered-dose nasal spray. This formulation is used to manage nasal symptoms associated with seasonal allergies or nonallergic vasomotor rhinitis.

Ophthalmic Solution

This medication is also available in the form of eye drops, known as an ophthalmic solution. It is used to treat itching of the eye caused by allergic conjunctivitis.

Question 11

What is the FDA approval status of Azelastine?

Accepted Answer

FDA Approval and Indications

Azelastine is approved by the U.S. Food and Drug Administration (FDA) for the management of symptoms related to allergies. Its approved uses vary by the method of administration:

Nasal Spray: This form is approved to treat seasonal allergic rhinitis in adults and children, perennial allergic rhinitis, and vasomotor rhinitis (non-allergic congestion and runny nose).

Ophthalmic Solution: These eye drops are approved to treat itchy eyes caused by allergic conjunctivitis.

Regulatory Status

Azelastine is available in several forms, and its regulatory status depends on the formulation:

Prescription Status: Higher concentrations and certain combination products that include other medications, such as steroids, are available by prescription only.

Over-the-Counter (OTC) Status: Some nasal spray versions of azelastine have been approved for over-the-counter sale, allowing consumers to purchase them without a prescription for the relief of allergy symptoms.

Safety and Warnings

The FDA has not issued any boxed warnings for azelastine, which are the most serious type of warning for medications. There are also no Risk Evaluation and Mitigation Strategies (REMS) required for this drug. Regulatory oversight continues through standard post-marketing surveillance to monitor for any new safety concerns.

Question 12

What should I know about Azelastine and nasal spray?

Accepted Answer

How Azelastine Nasal Spray Works

Azelastine is an antihistamine that works by blocking histamine, a substance in the body that causes allergic symptoms. Unlike many other antihistamines taken as pills, this medication is applied directly to the lining of the nose to reduce inflammation and congestion.

Common Uses

This nasal spray is used to treat symptoms such as sneezing, runny nose, and nasal itching caused by:

Seasonal allergies: Often referred to as hay fever.

Perennial allergies: Year-round triggers like dust mites or pet dander.

Nonallergic rhinitis: Conditions that cause a runny or stuffy nose but are not triggered by an allergen.

Administration Instructions

Proper technique is important for the medication to be effective and to minimize side effects:

Clear the nasal passages by blowing your nose gently.

If using the bottle for the first time or after a period of non-use, prime the pump by spraying it into the air until a fine mist is released.

Tilt your head slightly forward toward your toes.

Place the tip of the bottle into one nostril and point it slightly toward the outside of the nose, away from the center wall (septum).

Sniff gently while pressing the pump.

To avoid a bitter taste in the mouth, do not tilt your head back immediately after using the spray.

Safety and Side Effects

The most common side effect is a bitter taste in the mouth. Some users may also experience nasal irritation or a burning sensation. Because azelastine can cause drowsiness, users should be cautious when performing tasks that require alertness, such as driving, until they know how the medication affects them. Avoid consuming alcohol while using this spray, as it may increase sleepiness.
