Qvar

Asthma Maintenance

Qvar is used for the long-term prevention and control of asthma symptoms. It is a maintenance medication that helps manage the underlying inflammation in the airways, making it easier to breathe over time.

Symptom Prevention

When used daily as directed, Qvar helps to reduce the frequency and intensity of asthma-related issues, including:

• Wheezing
• Shortness of breath
• Coughing
• Chest tightness

This medication is typically prescribed for patients who require consistent, daily treatment to keep their asthma under control and to decrease the severity of future attacks.

Important Limitations

Qvar is not a rescue medication. It is important to understand the specific situations where it should not be used:

• It will not stop an asthma attack that has already started.
• It should not be used for the immediate relief of sudden breathing problems or acute bronchospasm.
• It is not intended for use in children under 4 years of age.

Patients are generally advised to have a separate fast-acting rescue inhaler available at all times to treat sudden symptoms.

Reducing Airway Inflammation

Qvar contains beclomethasone, which belongs to a class of drugs known as corticosteroids. When inhaled, the medication travels directly into the small passages of the lungs. It works by preventing certain cells in the lungs from releasing substances that cause inflammation.

Preventing Symptoms

By reducing swelling and irritation in the airways, Qvar helps to:

• Decrease the sensitivity of the airways to asthma triggers.
• Reduce the production of excess mucus.
• Keep the bronchial tubes open over time.

This medication is designed for long-term maintenance. It does not provide immediate relief during a sudden asthma attack. Instead, it works gradually over days or weeks of regular use to improve overall lung function and prevent breathing difficulties from occurring.

Common Side Effects

Many people using this medication do not experience serious side effects. Common symptoms may include:

• Headache
• Throat irritation or hoarseness
• Dry mouth or an unpleasant taste
• Cough
• Sinus pain or a stuffy nose
• Nausea

Serious Side Effects

Contact your doctor immediately if you experience any of the following serious side effects:

• Oral Thrush: White patches in your mouth or on your tongue.
• Breathing Problems: Sudden wheezing or increased trouble breathing immediately after using the inhaler.
• Signs of Infection: Fever, chills, or persistent sore throat.
• Vision Changes: Blurred vision, eye pain, or seeing halos around lights.
• Allergic Reactions: Rash, itching, swelling (especially of the face, tongue, or throat), or severe dizziness.
• Adrenal Issues: Extreme tiredness, muscle weakness, or unexplained weight loss.

To help prevent oral thrush and dry mouth, it is recommended to rinse your mouth with water and spit it out after each use of the inhaler.

Acute Asthma Episodes

Qvar is not a bronchodilator and is not intended for the rapid relief of acute bronchospasm. A separate rescue inhaler should be used for sudden asthma symptoms.

Fungal Infections

Localized infections of the mouth and throat with Candida albicans, also known as thrush, may occur. Rinsing the mouth with water without swallowing after each use can help reduce this risk.

Adrenal Insufficiency

Particular care is needed when individuals are transferred from systemic corticosteroids to inhaled corticosteroids. This transition can lead to adrenal insufficiency, which may be life-threatening during periods of physical stress, surgery, or severe asthma attacks.

Immunosuppression

Inhaled corticosteroids can weaken the immune system. People using this medication should avoid exposure to chickenpox or measles and should consult a healthcare provider if exposure occurs. Caution is advised for those with existing infections, such as tuberculosis or ocular herpes simplex.

Other Long-term Risks

• Paradoxical Bronchospasm: Inhaled medications may cause an immediate increase in wheezing after dosing. If this occurs, the medication should be discontinued.
• Bone Density: Long-term use of inhaled corticosteroids may lead to a decrease in bone mineral density, which is a risk factor for osteoporosis.
• Growth: Inhaled corticosteroids may cause a reduction in growth velocity when administered to children and adolescents.
• Eye Problems: Glaucoma, increased intraocular pressure, and cataracts have been reported with long-term use. Regular eye exams may be necessary.

Pregnancy

There are no adequate and well-controlled studies of Qvar in pregnant women. While animal studies have shown that corticosteroids can cause fetal harm when administered systemically at high doses, the amount of medication absorbed into the bloodstream from inhaled beclomethasone is relatively low.

It is important to consider that poorly controlled asthma during pregnancy increases the risk of complications for both the parent and the fetus, including:

• Preeclampsia (dangerously high blood pressure)
• Low birth weight
• Preterm delivery

Healthcare providers typically weigh the necessity of maintaining asthma control against the potential risks of the medication to determine the best course of treatment.

Breastfeeding

It is not known whether beclomethasone dipropionate is excreted in human milk. Other corticosteroids are known to be excreted in small amounts in breast milk. Because many drugs are excreted in human milk, caution is advised when using Qvar while nursing.

Parents should discuss the benefits of breastfeeding and the clinical need for the medication with their doctor to make an informed decision.

Available Forms

Qvar is supplied as a breath-actuated inhalation aerosol. This delivery system is designed to release the medication automatically when the patient breathes in through the mouthpiece, which removes the need to coordinate pressing a canister with inhalation.

The device includes the following components:

• A breath-actuated inhaler unit.
• A built-in dose counter to track remaining medication.
• A hinged cap to protect the mouthpiece.

FDA Approval Status

Qvar (beclomethasone dipropionate) is approved by the U.S. Food and Drug Administration (FDA) for the maintenance treatment of asthma. It is classified as a prophylactic therapy, meaning it is used to prevent symptoms by reducing inflammation in the airways over time.

Approved Indications

The FDA has approved Qvar for the following specific use:

• Maintenance treatment of asthma as preventative therapy in patients 4 years of age and older.

Qvar is not indicated for the treatment of acute bronchospasm. It is not a rescue medication and will not stop an asthma attack that has already started.

Regulatory and Safety Information

There are currently no boxed warnings or Risk Evaluation and Mitigation Strategies (REMS) required by the FDA for Qvar. It is available only by prescription. Regulatory labeling for this medication emphasizes that it must be used consistently to be effective, and patients should not stop treatment abruptly without consulting a healthcare provider.

How Qvar Manages Asthma

Qvar is prescribed as a maintenance medication to help control asthma symptoms and prevent future attacks. It contains beclomethasone, a corticosteroid that targets inflammation directly in the lungs. By reducing the swelling and mucus production in the airways, it makes the lungs less sensitive to triggers like allergens or cold air.

Preventative Use

It is important to understand that Qvar is a controller medication and not a rescue inhaler. It will not stop an asthma attack that has already started. Patients should always have a separate fast-acting rescue inhaler available for sudden breathing problems. To be effective, Qvar must be used every day at the same time, even if the patient feels well and has no symptoms.

Treatment Goals

The primary goals of using Qvar for asthma include:

• Reducing the frequency and severity of asthma attacks.
• Improving overall lung function.
• Decreasing the need for rescue medications.
• Allowing for better participation in daily activities and exercise.

Full benefits of the medication may not be noticed for one to two weeks after starting treatment. If asthma symptoms do not improve or if they get worse while using this medication, patients should contact a healthcare provider.
