How Does Qvar Work?

Qvar contains beclomethasone dipropionate, a corticosteroid that acts on glucocorticoid receptors in airway tissues. It reduces inflammatory activity, swelling, and other processes that contribute to airway sensitivity and narrowing in asthma. Regular inhalation helps decrease the frequency and severity of asthma symptoms and may improve lung function over time. Beclomethasone is converted into an active metabolite that contributes to its anti-inflammatory effects. Qvar does not directly relax airway muscles quickly enough to treat acute bronchospasm. Patients should continue to have an appropriate rescue medication when prescribed.

What Type of Asthma Does Qvar Treat?

Qvar RediHaler is approved for maintenance treatment of asthma in adults and children aged four years and older. It is used as preventive therapy for patients who need regular inhaled corticosteroid treatment to control airway inflammation. A healthcare professional evaluates symptom frequency, previous asthma medication use, exacerbation history, and lung function before determining the appropriate dose. Qvar RediHaler is not intended as the primary treatment for status asthmaticus or other acute asthma episodes requiring immediate intervention. It is also not approved specifically for chronic obstructive pulmonary disease. Patients experiencing sudden worsening of asthma symptoms require prompt assessment.

How Should Qvar Be Used?

Qvar RediHaler is administered by oral inhalation twice daily, generally about 12 hours apart. For children aged four through 11 years, the recommended starting dose is 40 mcg twice daily, with a maximum of 80 mcg twice daily. For patients aged 12 years and older, starting doses commonly range from 40 mcg to 80 mcg twice daily when not previously using an inhaled corticosteroid, with a maximum recommended dose of 320 mcg twice daily. The breath-actuated device does not require priming or shaking and must not be used with a spacer. Rinse the mouth with water and spit it out after each dose to reduce the risk of oral thrush.

What Are the Side Effects and Warnings of Qvar?

Common adverse effects include oral thrush, throat discomfort, upper respiratory symptoms, and irritation of the nose or throat. Long-term or higher-dose corticosteroid exposure can contribute to adrenal suppression, reduced bone mineral density, and slowed growth in children. Glaucoma, cataracts, and increased intraocular pressure have also been reported with inhaled corticosteroids. Patients with active infections or a history of certain eye conditions require additional monitoring. Qvar should not replace a rescue inhaler during acute asthma symptoms. Persistent mouth soreness, significant vision changes, or worsening breathing problems require medical evaluation.
