ProAir is a brand name for albuterol sulfate, a short-acting beta agonist (SABA) bronchodilator used as a rescue inhaler for asthma and chronic obstructive pulmonary disease (COPD). It is one of the most widely prescribed medications in the United States, used by tens of millions of patients.
ProAir is FDA-approved for the treatment or prevention of bronchospasm in patients 4 years of age and older with reversible obstructive airway disease, and for the prevention of exercise-induced bronchospasm (EIB). It begins working within 5 minutes of inhalation and provides 4–6 hours of bronchodilation.
ProAir has been available in three formulations: ProAir HFA (pressurized metered-dose inhaler, discontinued as brand in October 2022 — authorized generic continues), ProAir RespiClick (breath-activated dry powder inhaler, still available as brand), and ProAir Digihaler (smart inhaler, discontinued). Other albuterol brands include Ventolin HFA and Proventil HFA.

ProAir (albuterol) works as a beta-2 adrenergic agonist. When inhaled, albuterol binds to beta-2 receptors on the smooth muscle surrounding the bronchial airways. This binding triggers an intracellular signaling cascade that increases cyclic AMP (cAMP), which reduces calcium levels inside the smooth muscle cells, causing the muscle to relax.
The result is bronchodilation — the airways widen, air can flow more freely in and out of the lungs, and breathing becomes easier. This effect begins within 5 minutes of inhalation and peaks within 30–60 minutes, with duration of 4–6 hours.
Important: albuterol treats bronchospasm (airway muscle tightening) but does NOT treat the underlying airway inflammation that drives chronic asthma. Inhaled corticosteroids (ICS) address the inflammation component and are essential in most persistent asthma treatment plans.
90 mcg/actuation — HFA metered-dose inhaler (200 actuations)
Standard ProAir HFA / generic albuterol HFA rescue inhaler. Shake before use.
90 mcg/actuation — Dry powder inhaler (RespiClick, 200 doses)
Breath-activated DPI. No shaking or priming needed. Contains lactose.
2.5 mg/3 mL — Inhalation solution (nebulizer)
Unit-dose vials for use with nebulizer machine. Shortage affected formulation.
ProAir and generic albuterol HFA inhalers are available at most pharmacies in 2026, but local stock-outs occur — particularly during peak respiratory virus season (October through March). The ProAir HFA brand was discontinued by Teva in October 2022; authorized generics continue to be manufactured and distributed. The albuterol nebulizer solution form has been on the FDA shortage list since October 2022 but is improving with new manufacturers approved in late 2025 and early 2026.
Availability challenges are most common during flu and RSV season when demand spikes, or during pollen season. When your pharmacy is out of stock, other brands (Ventolin HFA, Proventil HFA) contain the same active ingredient and may be available nearby. ProAir RespiClick (dry powder form) has not been significantly affected by the same supply issues.

Telehealth availability: ProAir can be prescribed via telehealth without in-person visit requirements. Telehealth platforms like Teladoc, MDLive, and Sesame can connect patients with providers for albuterol prescriptions and refills. This makes access particularly convenient when a patient has moved, doesn't have an established prescriber, or needs a prescription for an alternative brand quickly due to a pharmacy shortage.
No. ProAir (albuterol) is NOT a controlled substance. It is not scheduled by the DEA and has no special federal restrictions on prescribing or dispensing.
Because albuterol is not a controlled substance, any licensed prescriber (MDs, DOs, NPs, PAs) can prescribe it without special DEA registration. It can be prescribed via telehealth without in-person visit requirements that apply to controlled substances. Refills can be provided without quantity restrictions that apply to scheduled medications, and pharmacy transfers are straightforward.
Most common side effects (usually mild and temporary):
Tremor or shakiness (especially hands)

Ventolin HFA (albuterol)
Same active ingredient (albuterol sulfate 90 mcg/actuation), different manufacturer (GSK). Slightly cooler spray, lower fine particle dose than ProAir HFA in studies. Requires new prescription to switch.
Proventil HFA (albuterol)
Same active ingredient as ProAir, Merck brand. Less commonly stocked but an effective alternative. Requires new prescription.
Levalbuterol (Xopenex HFA)
Purified R-enantiomer of albuterol; delivers 45 mcg/actuation. May suit patients with significant albuterol side effects. Typically more expensive ($60–$100+ without insurance).
Airsupra (albuterol/budesonide)
Combination rescue inhaler adding anti-inflammatory budesonide. For adults with asthma. High cost without insurance; savings card available for commercially insured patients.

MAO Inhibitors (phenelzine, tranylcypromine, selegiline)
majorCan dramatically amplify albuterol's cardiovascular effects — potentially causing dangerous blood pressure spikes or arrhythmias. Avoid use within 2 weeks of stopping an MAOI.
Tricyclic Antidepressants (amitriptyline, nortriptyline, imipramine)
majorCan potentiate albuterol's cardiovascular effects. Avoid combination when possible; if necessary, use lowest effective albuterol dose and monitor cardiovascular status.
Beta-Blockers (propranolol, metoprolol, atenolol, carvedilol)
majorBlock beta-2 receptors — the same receptors albuterol needs to open the airways. Non-selective beta-blockers can make albuterol less effective and potentially cause bronchospasm. Cardioselective beta-blockers have less impact at lower doses.
Digoxin (Lanoxin)
moderateAlbuterol may decrease digoxin blood levels by up to 22%, potentially reducing its effectiveness. Monitor digoxin levels if albuterol is used frequently.
Diuretics (furosemide, hydrochlorothiazide)
moderateAdditive potassium-lowering effect. Combined use can lead to significant hypokalemia. Monitor potassium levels, especially in patients using albuterol frequently.
Other Short-Acting Bronchodilators
moderateUsing multiple SABAs simultaneously increases cardiovascular side effect risk. Avoid using two albuterol products at the same time without medical guidance.
ProAir (albuterol) is one of the most important rescue medications in respiratory care. For patients with asthma or COPD, having a working, in-stock rescue inhaler is essential to safety. The albuterol supply challenges since 2022 have made this more complicated than it should be — but with improving manufacturer supply in 2026 and smart strategies for finding your medication, most patients can stay protected.
Key takeaways: refill your inhaler before it's empty, know the alternative brands that contain the same medication, use GoodRx or SingleCare to reduce costs, and don't ration your rescue inhaler during an asthma flare. If you're unsure whether your asthma is adequately controlled, talk to your doctor about whether additional controller therapy might reduce your reliance on rescue medication.
