Proventil HFA Uses
Proventil HFA is an inhaler licensed to treat asthma and other lung problems. Other approved Proventil HFA uses involve preventing asthma attacks and exercise-induced asthma. Some "off-label" uses of Proventil HFA include the treatment of hyperkalemia and difficulty breathing resulting from conditions such as pneumonia or the flu.
Proventil® HFA (albuterol inhaler) is a prescription medication used to treat asthma and other similar lung problems. It is part of a class of asthma drugs known as beta-adrenergic receptor agonists, or beta agonists for short.
Asthma is a chronic disease that affects your airways, which are the tubes that carry air into and out of your lungs. If you have asthma, the inside walls of your airways are inflamed (swollen). The inflammation makes the airways very sensitive, and they tend to react strongly to things that you are allergic to or find irritating. When the airways react, they narrow and less air flows to your lungs. This is called bronchospasm and causes asthma symptoms like wheezing (a whistling sound when you breathe), coughing, tightness in the chest, and trouble breathing.
While there is no asthma cure, asthma can be controlled. There are many different asthma treatments, and Proventil HFA represents one of the most basic and most important types of treatment for asthma relief. Proventil HFA is a "rescue" asthma inhaler, which can help improve breathing very quickly. Even if you take asthma controller medications, it is important to always have a rescue asthma medication available to relieve an attack.
Proventil HFA is approved to both treat and prevent asthma attacks. Because Proventil HFA is short-acting, it is not necessarily the best asthma medication for preventing asthma attacks in general. However, it is an excellent medication for treating asthma attacks or preventing exercise-induced asthma attacks (see Asthma and Exercise).
Asthma is not the only cause of bronchospasm. Proventil HFA can also treat bronchospasm due to other lung problems, such as chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis.
