No, Ventolin HFA isn’t a steroid. Ventolin HFA is a short-acting beta2-agonist (SABA). It works by relaxing the muscles around your airways. This allows air to flow better as it moves in and out of your lungs. SABAs work quickly to make it easier for you to breathe.
Steroids, on the other hand, work by reducing inflammation in your body, including in your lungs. Steroids work over time to improve airflow through your lungs. Many people with asthma need to take both a SABA and a steroid to control their asthma symptoms.
