QNASL

Allergy Symptom Relief

QNASL is used to manage nasal symptoms caused by allergic rhinitis. This includes seasonal allergies, often referred to as hay fever, which are triggered by outdoor allergens like pollen. It is also used for perennial allergies, which occur year-round and are typically caused by indoor allergens such as dust mites, animal dander, or mold.

The medication helps relieve several common symptoms, including:

• Sneezing
• Runny nose
• Nasal congestion (stuffy nose)
• Itching of the nose

Patient Population

QNASL is approved for use in adults and children who are at least 4 years of age. It is designed for regular, daily use to manage symptoms rather than providing immediate relief for a sudden allergy attack.

Other Uses

In some cases, beclomethasone nasal products may be used to prevent nasal polyps from returning after they have been surgically removed. It works by reducing inflammation in the nasal passages to help keep the airway clear.

Mechanism of Action

QNASL contains beclomethasone dipropionate, which belongs to a class of medications known as corticosteroids. These drugs are designed to reduce inflammation in the body by mimicking the effects of natural hormones.

When the medication is sprayed into the nose, it works directly on the nasal lining to manage the body's immune response to allergens. It helps to:

• Reduce swelling: It decreases the inflammation of the nasal tissues that leads to a stuffy feeling or congestion.
• Block inflammatory chemicals: It inhibits the release of various natural substances in the body that trigger allergic reactions.
• Decrease mucus production: It helps limit the excess fluid that causes a runny nose.

While the precise mechanism of how corticosteroids work to treat allergic rhinitis is not fully understood, they are known to have multiple anti-inflammatory effects. By controlling these responses, the medication provides relief from common symptoms such as sneezing, itching, and nasal congestion.

Common Side Effects

Many people using this medication do not experience significant side effects. When they do occur, common issues may include:

• Nasal dryness, burning, or stinging
• Nosebleeds
• Headache
• Sore throat or cough
• Unpleasant taste or smell

Serious Side Effects

Contact a healthcare provider immediately if you experience any of the following serious symptoms:

• Signs of an allergic reaction, such as rash, hives, or swelling of the face, lips, or throat
• Vision problems, including blurred vision or eye pain
• White patches in the nose or back of the throat
• Persistent crusting or sores inside the nose
• Signs of infection, such as fever or chills
• Severe or frequent nosebleeds

In rare cases, long-term use of nasal corticosteroids may lead to a hole in the cartilage of the nose (nasal septum perforation) or slow the healing of wounds in the nose. Children using this medication should have their growth monitored by a doctor to ensure it is not affected by the steroid.

Local Nasal Effects

Nasal corticosteroids can cause localized adverse reactions, including nosebleeds (epistaxis), nasal ulceration, and fungal infections (Candida albicans) in the nose or throat. There is also a risk of nasal septal perforation. Due to the inhibitory effect of corticosteroids on wound healing, this medication is generally not used until healing has occurred following recent nasal surgery or trauma.

Immune System and Infection

This medication can suppress the immune system, increasing susceptibility to infections. Individuals who have not had chickenpox or measles should avoid exposure while using this treatment. It should be used with caution in patients with active or quiescent tuberculosis, untreated fungal or bacterial infections, or ocular herpes simplex.

Ocular Effects

Glaucoma, cataracts, and increased intraocular pressure have been reported with the use of nasal corticosteroids. Close monitoring is recommended for individuals with a history of these conditions or those who experience changes in vision.

Systemic Effects and Growth

High doses or prolonged use may lead to hypercorticism and adrenal suppression. In pediatric patients, nasal corticosteroids may cause a reduction in growth velocity. Healthcare providers typically monitor the growth of children receiving long-term treatment.

Hypersensitivity

Serious allergic reactions, including anaphylaxis, angioedema, rash, and hives, may occur. The medication is contraindicated in individuals with a known hypersensitivity to beclomethasone dipropionate or any of its ingredients.

Pregnancy

There are no adequate and well-controlled studies regarding the use of QNASL in pregnant women. While animal studies have shown that corticosteroids can cause birth defects when administered systemically at high doses, the amount of medication absorbed into the bloodstream after using the nasal spray is generally low.

If you are pregnant or planning to become pregnant, discuss the risks and benefits with your healthcare provider. In some cases, infants born to mothers who used corticosteroids during pregnancy may need to be monitored for signs of underactive adrenal glands, also known as hypoadrenalism.

Breastfeeding

It is not known if the active ingredient in QNASL passes into human breast milk. While other corticosteroids are known to enter breast milk, the low levels absorbed from nasal administration make it less likely to reach the infant in significant amounts. Because many drugs are excreted in human milk, caution is advised when using this medication while breastfeeding.

Consult with a healthcare professional to determine if the benefits of treatment outweigh any potential risks to the nursing infant.

Available Forms

QNASL is supplied as a non-aqueous, pressurized nasal aerosol. It is administered using a metered-dose inhaler designed for intranasal use. The medication is available in formulations specifically intended for different age groups, including adults, adolescents, and children.

• Nasal aerosol spray

FDA Approval History

The U.S. Food and Drug Administration (FDA) first approved QNASL (beclomethasone dipropionate) nasal aerosol in March 2012. The initial approval was for the treatment of nasal symptoms of seasonal and perennial allergic rhinitis in adults and adolescents 12 years of age and older. In October 2014, the FDA expanded this approval to include a formulation for children aged 4 to 11 years.

Approved Indications

QNASL is indicated for the management of nasal symptoms associated with:

• Seasonal Allergic Rhinitis: Nasal symptoms triggered by seasonal allergens such as pollen from trees, grasses, and weeds.
• Perennial Allergic Rhinitis: Year-round nasal symptoms triggered by indoor allergens such as dust mites, animal dander, and mold.

Regulatory Status

QNASL is available only by prescription. It is not currently subject to a Boxed Warning, which is the FDA's most serious warning level, nor is it under a Risk Evaluation and Mitigation Strategy (REMS) program. As a corticosteroid, its regulatory labeling includes standard precautions regarding the monitoring of growth in pediatric patients and the risk of increased intraocular pressure, glaucoma, or cataracts with long-term use.

Delivery Method and User Experience

A primary feature of QNASL is its delivery system. Unlike many liquid nasal sprays that may drip down the throat or feel wet in the nose, QNASL is a non-aqueous (dry) aerosol. This dry sensation is often a significant factor for patients who find liquid sprays uncomfortable or irritating.

Effectiveness for Allergy Symptoms

QNASL is used to treat symptoms of allergic rhinitis, including sneezing, runny nose, and nasal congestion. It is important to note that this medication does not provide immediate relief. Most users will need to use the medication consistently for several days before noticing the full benefits.

Commonly Reported Side Effects

While many people tolerate the medication well, some users may experience side effects that influence their overall experience. These can include:

• Nasal dryness or irritation
• Nosebleeds
• Headaches
• Unpleasant taste or smell

If severe irritation or damage to the nasal tissue occurs, users are advised to stop use and consult a healthcare provider.
