Flovent vs. Xopenex
See how Flovent and Xopenex compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Flovent is a daily controller inhaler that reduces airway inflammation over time, while Xopenex is a fast-acting bronchodilator used to relieve or prevent sudden bronchospasm.
Flovent must be used on a fixed twice-daily schedule even when symptoms are absent, whereas Xopenex is typically used as needed or before a known trigger like exercise.
Neither drug replaces the other: Flovent will not stop an asthma attack already in progress, and Xopenex does not treat the underlying airway inflammation.
Flovent vs. Xopenex Drug Summary
Flovent
Flovent (fluticasone propionate) is an inhaled corticosteroid used for the long-term, twice-daily maintenance treatment of asthma in patients 4 years and older. It works by reducing airway inflammation over time and is not intended for treating a sudden asthma attack.
Xopenex
Xopenex (levalbuterol) is a short-acting beta2-agonist bronchodilator used to treat or prevent bronchospasm from asthma or other reversible airway conditions. It is taken as needed via a nebulizer or HFA inhaler and works within minutes to relax airway muscles.

Flovent vs. Xopenex Indications
Flovent
Flovent is FDA-approved for maintenance asthma treatment in patients aged 4 and older, including those who need oral corticosteroid therapy. It is taken on a fixed twice-daily schedule to control inflammation over time, not to stop an attack already underway.
Maintenance treatment of asthma in patients 4 years and older
Asthma in patients who require oral corticosteroid therapy
Not approved for relief of acute bronchospasm
Not approved for status asthmaticus or acute episodes
Xopenex
Xopenex is FDA-approved to treat or prevent bronchospasm caused by reversible obstructive airway disease, including asthma. It is used as needed, either during an attack or shortly before a known trigger, rather than on a fixed daily schedule.
Treatment of acute bronchospasm from reversible airway disease
Prevention of bronchospasm before exposure to a trigger
Available as nebulizer solution or HFA inhaler
Not approved for management of preterm labor
Flovent vs. Xopenex Pros and Cons
Flovent
Flovent's clinical role is long-term inflammation control, so its benefits build over weeks rather than minutes. Insurance coverage is generally good since inhaled corticosteroids are standard asthma therapy, and cost is typically modest with the current authorized generic.
Pros
Reduces frequency and severity of asthma flare-ups over time
Approved for maintenance therapy in children as young as 4
Available in two inhaler formats (HFA aerosol and Diskus powder)
Roughly $50 to $150 per month without insurance
Cons
Does not relieve symptoms during an active asthma attack
Can cause oral thrush; rinsing the mouth after use is needed
Long-term use may reduce bone density and slow growth in children
Brand-name product discontinued, so patients now rely on generics
Xopenex
Xopenex's clinical role is fast, short-term relief of airway constriction, with effects felt within minutes. It is commonly used as a rescue medication and must be paired with a controller drug like an inhaled corticosteroid for anyone with persistent asthma.
Pros
Works within minutes to relieve acute bronchospasm
Nebulizer form works well for patients who struggle with inhalers
Single-isomer formula may cause less heart stimulation than albuterol
Roughly $55 to $120 per month without insurance
Cons
Does not treat the underlying airway inflammation
Can cause tachycardia and other cardiovascular effects
Overuse can mask worsening asthma control
Needs a separate daily controller for chronic asthma management
