ProAir (albuterol) is a fast-acting rescue inhaler used to quickly relieve asthma symptoms and bronchospasm.
The typical adult dose is 2 inhalations every 4 to 6 hours as needed for symptoms. Do not exceed 12 inhalations within 24 hours unless directed by a healthcare provider.
Children ages 4 to 11 are usually prescribed 2 inhalations every 4 to 6 hours as needed, but dosing should always follow a doctor’s instructions.
Using the inhaler correctly is important so the medication reaches the lungs and provides effective symptom relief.
If you miss a dose, use ProAir when you remember if you still need symptom relief, but do not exceed the recommended maximum daily dose.

ProAir is a brand name for albuterol sulfate, a bronchodilator that helps open up airways in the lungs. It’s commonly prescribed for people with asthma, chronic obstructive pulmonary disease (COPD), or other conditions that cause bronchospasm. When you experience wheezing, shortness of breath, or chest tightness, ProAir can provide quick relief by relaxing the muscles around your airways.
Because it acts fast, ProAir is often called a “rescue inhaler.” It’s not meant for daily long-term control but rather for immediate symptom management. Understanding the correct dosage and timing is crucial to getting the most benefit without risking side effects.

For asthma symptoms, adults typically use 2 inhalations of ProAir (albuterol) every 4 to 6 hours as needed to relieve sudden breathing problems caused by bronchospasm. If symptoms do not improve or continue to worsen after using the inhaler, you should seek medical attention promptly.
Children ages 4 to 11 generally follow the same dosing pattern, but the inhaler should always be used under adult supervision to ensure the correct technique and dose.
ProAir can also be used to prevent breathing problems triggered by exercise. The usual recommendation is:
2 inhalations taken 15 to 30 minutes before exercise
This helps open the airways and reduce the chance of bronchospasm during physical activity.
People with COPD may use ProAir to relieve sudden breathing symptoms. The dosing is usually similar to asthma treatment:
2 inhalations every 4 to 6 hours as needed
However, COPD treatment plans often include multiple medications, so it’s important to follow your healthcare provider’s specific instructions.
Most adults use:
2 inhalations every 4 to 6 hours as needed
The maximum recommended amount is 12 inhalations in 24 hours unless directed otherwise by a healthcare provider.
Using more than the recommended amount can increase the risk of side effects such as:
rapid heartbeat
shakiness or tremors
nervousness
headache
If you need the inhaler more often than usual, it may mean your asthma or lung condition is not well controlled and you should contact your healthcare provider.
Children ages 4 to 11 usually take:
2 inhalations every 4 to 6 hours as needed
Children under age 4 should only use ProAir if prescribed and directed by a healthcare provider.
Because inhaler technique is important, adult supervision and proper instruction help ensure the medication reaches the lungs effectively.
ProAir is generally used only when symptoms occur, rather than on a fixed schedule.
If you forget to use it when symptoms start, use the inhaler when you remember if symptoms are still present. Do not take extra doses or exceed the maximum daily limit.
People with heart conditions, such as arrhythmias or high blood pressure, should use ProAir carefully. Albuterol can sometimes increase heart rate or blood pressure, so your doctor may monitor your symptoms or adjust your treatment plan.
People with hyperthyroidism may be more sensitive to stimulatory effects of albuterol, such as palpitations, nervousness, or tremors. Your healthcare provider may recommend closer monitoring or dose adjustments.
Using too much ProAir can cause serious side effects, including:
chest pain
very rapid or irregular heartbeat
severe tremors
headache
seizures
If you believe you have taken too much ProAir, seek emergency medical care immediately.
ProAir is a rescue inhaler, meaning it is used to relieve sudden symptoms. It does not replace long-term asthma control medications. If you rely on your rescue inhaler frequently, your treatment plan may need to be reassessed.
Use proper inhaler technique: shake the inhaler, breathe out fully, then inhale slowly while pressing the canister.
Keep track of doses so you know when the inhaler is running low.
Store the inhaler at room temperature, away from extreme heat or freezing.
Contact your healthcare provider if side effects occur or if breathing symptoms worsen.
Using ProAir correctly and following your treatment plan helps ensure the medication provides fast and effective relief when you need it most.

Yes, taking two inhalations 15 to 30 minutes before exercise can help prevent exercise-induced bronchospasm.
If symptoms persist after using ProAir, seek emergency medical care immediately, as this could indicate a severe asthma attack.
ProAir is intended for quick relief, not daily control. Frequent use may signal poorly controlled asthma and requires a doctor’s evaluation.
Yes, children 4 years and older can use ProAir under adult supervision and doctor guidance.
Keep track of doses used. Most inhalers have a dose counter. Replace it before it runs out to ensure you always have medication when needed.
