Asthma Inhalers Guide – Types, Uses, and Benefits

Overview of the two main types of asthma inhalers: rescue inhalers (short-acting)

There are two main types of asthma inhalers commonly used to manage asthma symptoms: rescue inhalers and controller inhalers. In this article, we will focus on rescue inhalers, also known as short-acting inhalers, and discuss their purpose and key features.

What are rescue inhalers?

Rescue inhalers are medications that provide rapid relief from asthma symptoms by quickly opening the airways to make breathing easier. They are typically used during asthma attacks or when experiencing symptoms such as wheezing, shortness of breath, or chest tightness. Rescue inhalers are considered short-acting bronchodilators as they act quickly to relax the muscles around the airways.

Commonly used rescue inhalers

  • Albuterol (ProAir HFA, Ventolin HFA, Proventil HFA): A widely used rescue inhaler that helps relieve symptoms of bronchospasm and asthma attacks.
  • Levalbuterol (Xopenex): Another short-acting bronchodilator that works similarly to albuterol and is used for quick relief of asthma symptoms.

These are just a few examples of rescue inhalers available on the market, and your healthcare provider will recommend the most suitable one based on your individual needs.

How do rescue inhalers work?

Rescue inhalers contain a medication called a beta-agonist, which binds to beta-receptors in the lungs and airways. This binding activates these receptors, causing the muscles surrounding the airways to relax, allowing them to widen and improve airflow.

“Rescue inhalers are crucial for managing acute asthma symptoms and should be used as directed by your healthcare provider to prevent complications.”

Inhalers deliver the medication directly to the lungs, providing quick and targeted relief. They are easy to use and portable, making them convenient for individuals with asthma to carry with them at all times.

Best practices for using rescue inhalers

It is essential to use rescue inhalers correctly to ensure effective relief of asthma symptoms. Here are some best practices to keep in mind:

  • Follow your healthcare provider’s instructions on when and how to use the inhaler.
  • Keep track of the number of doses remaining in the inhaler to know when to refill it.
  • Carry your inhaler with you at all times, especially when engaging in physical activity or traveling.


Rescue inhalers play a crucial role in managing acute asthma symptoms and providing rapid relief when needed. By understanding how these inhalers work and following best practices for their use, individuals with asthma can effectively control their symptoms and improve their quality of life.
