What is a rescue inhaler?

A rescue inhaler helps to expand a person’s airways during an asthma attack. Rescue inhalers dispense a type of medication called a bronchodilator, which expands (dilates) the airways, known as bronchioles. Here, we explore the different types of rescue inhalers. We also discuss how these inhalers are used and any associated side effects.

Can you use a rescue inhaler if you have asthma?

Someone with asthma may also use a rescue inhaler before a workout to prevent an attack. A person with chronic obstructive pulmonary disease (COPD) may also benefit from using a rescue inhaler if their symptoms worsen. Like asthma, COPD causes breathing difficulties.

How long does a rescue inhaler last?

Your rescue inhalers should relieve your symptoms in 15 to 20 minutes. The effects of the medication typically last between four and six hours. In addition to relieving the symptoms of an asthma attack, a rescue inhaler can be used prior to a strenuous workout to help prevent an asthma attack from occurring.

What are the side effects of a rescue inhaler?

Long-acting medications commonly used in rescue inhalers include budesonide and formoterol. Rare side effects include an upset stomach and sleeplessness. Any person diagnosed with asthma should keep their rescue inhaler close by at all times in case of an attack. Use a rescue inhaler for relief at the first sign of any of these symptoms.
