Albuterol Sulfate HFA
Albuterol Sulfate HFA is a prescription inhaler used to treat or prevent bronchospasm in individuals with reversible obstructive airway diseases, such as asthma and chronic obstructive pulmonary disease (COPD). It is also used to prevent exercise-induced bronchospasm. Albuterol belongs to the class of medications known as short-acting beta-agonists (SABAs) and works by relaxing the muscles in the airways, allowing easier breathing. The "HFA" in the name stands for hydrofluoroalkane, which is the propellant used in the inhaler.
Drug Availability and Controlled Substance Status
Albuterol Sulfate HFA is available by prescription and can be found in most pharmacies. It is commonly available in a metered-dose inhaler (MDI) form, delivering a specific amount of albuterol with each inhalation. Each inhaler typically contains 200 doses of 90 mcg of albuterol per spray. Albuterol Sulfate HFA is not classified as a controlled substance.

Comprehensive Drug Guide
How Does Albuterol Sulfate HFA Work?
Albuterol Sulfate HFA works by stimulating beta-2 adrenergic receptors in the lungs, leading to the relaxation of bronchial smooth muscle. This action helps to open the airways, making it easier to breathe. Albuterol is fast-acting, typically starting to work within minutes, and its effects can last for 4 to 6 hours. It is primarily used as a rescue medication for acute bronchospasm or as a preventative measure before exercise.
Common Dosages
Albuterol Sulfate HFA inhalers commonly deliver 90 mcg of albuterol per spray. The typical inhaler contains 200 metered doses. Dosage instructions usually involve taking 1 to 2 inhalations every 4 to 6 hours as needed for bronchospasm relief. For exercise-induced bronchospasm, 2 inhalations taken 15 to 30 minutes before exercise is common.
Typical Dosing
The typical dosing of Albuterol Sulfate HFA involves:
- For bronchospasm: 1 to 2 inhalations every 4 to 6 hours as needed.
- For exercise-induced bronchospasm: 2 inhalations taken 15 to 30 minutes before exercise.
Patients should follow their healthcare provider's instructions closely and should not exceed the recommended number of inhalations.
Typical Dosing
FDA Approved Indications

Advice From The Pharmacist
When using Albuterol Sulfate HFA, it is important to shake the inhaler well before each use and to follow the proper inhalation technique. If you find yourself using the inhaler more frequently than prescribed, this may be a sign that your asthma or COPD is not well-controlled, and you should consult your healthcare provider. Keep track of the number of doses used, and replace the inhaler when the counter shows zero. If you experience any unusual symptoms, such as increased heart rate or tremors, contact your healthcare provider.
