Pulmicort vs. Xopenex
See how Pulmicort and Xopenex compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Pulmicort is an inhaled corticosteroid taken twice daily to prevent asthma symptoms over time, while Xopenex is a fast-acting bronchodilator used to treat or prevent sudden bronchospasm.
Pulmicort does not relieve an asthma attack in progress, so people who use it typically also carry a rescue medication like Xopenex for acute symptoms.
Xopenex works within minutes but does not treat the underlying airway inflammation that Pulmicort is designed to control long-term.
Pulmicort vs. Xopenex Drug Summary
Pulmicort
Pulmicort (budesonide) is an inhaled corticosteroid used for the long-term maintenance treatment of asthma in people 6 years and older. It is taken twice daily through a Flexhaler dry powder inhaler to reduce airway inflammation and prevent symptoms over time, not to relieve an attack in progress.
Xopenex
Xopenex (levalbuterol) is a short-acting beta2-agonist bronchodilator used to treat or prevent bronchospasm in people with reversible obstructive airway disease. It is delivered by nebulizer solution or HFA inhaler and works within minutes by relaxing the muscles around the airways.

Pulmicort vs. Xopenex Indications
Pulmicort
Pulmicort is FDA-approved for the maintenance treatment of asthma in patients 6 years and older, used regularly to prevent symptoms rather than treat them in the moment. It is sometimes used off-label to help manage eosinophilic esophagitis.
Long-term asthma control, not rescue therapy
Approved for ages 6 and up (Flexhaler)
Off-label use for eosinophilic esophagitis
Respules nebulizer form available for young children
Xopenex
Xopenex is FDA-approved to treat or prevent bronchospasm in people with reversible obstructive airway disease, such as asthma. It is used as needed for quick relief rather than as a daily controller medication.
Fast-acting relief for bronchospasm
Used as needed, not on a fixed schedule
Available as nebulizer solution or HFA inhaler
Not a substitute for daily corticosteroid use
Pulmicort vs. Xopenex Pros and Cons
Pulmicort
Pulmicort works by reducing the airway inflammation that drives asthma over time, which can lower how often flare-ups happen in the first place. It requires consistent daily use and provides no fast relief if symptoms flare up suddenly.
Pros
Treats the underlying inflammation behind asthma
Approved for children as young as 6
Respules option for younger kids not using Flexhaler
Not habit-forming since it is not a bronchodilator
Cons
Provides no relief during an active asthma attack
Requires twice-daily dosing even when feeling well
Contains trace milk protein, risky for severe milk allergy
Xopenex
Xopenex acts within minutes to open the airways during bronchospasm, making it useful for sudden symptoms. It does not address the inflammation behind asthma, so it works best alongside a controller medication rather than on its own.
Pros
Starts working within minutes for acute symptoms
No daily maintenance dosing required
Available in a portable HFA inhaler
Roughly $55 to $120 per month without insurance
Cons
Does not treat underlying airway inflammation
Can cause tachycardia or other cardiac effects
Overuse can be dangerous and needs careful dose limits
