What is ProAir Digihaler?

ProAir Digihaler (albuterol sulfate) is a digital rescue inhaler for the quick-relief of asthma symptoms. It contains a type of medication called a short-acting beta₂-adrenergic receptor agonist and is a bronchodilator that works by helping to relax the smooth muscles in your airways, making it easier to breathe.

ProAir Digihaler was the first digital inhaler to be approved for use by the US Food and Drug Administration (FDA) when it was granted approval in 2018. It has a built-in electronic sensor to detect, record and store your inhaler usage data. It is also breath-actuated, which means that it is activated to deliver a metered-dose of dry powder containing your medication when you inhale with you lips tightly closed around the mouthpiece of the inhaler.

ProAir Digihaler may be used with an app through Bluetooth wireless technology. It can check how you inhale by measuring your inspiratory flow rate and also track how often you use your inhaler.

Two other ProAir inhalers containing albuterol sulfate are also available including:

• ProAir HFA, which releases a fine mist of medication
• ProAir RespiClick, which is a dry powder inhaler without the electronic sensor

What is ProAir Digihaler used for?

It is not known if ProAir Digihaler is safe and effective in children under 4 years of age.
