Educational Pearls:

What is a Rescue Inhaler?

• A rescue inhaler is a medication for people with asthma to quickly reverse the symptoms of an asthma attack.

• Historically albuterol (Short Acting Beta Agonist (SABA)) monotherapy has been the mainstay rescue inhaler. This is because albuterol works fast and is relatively cheap. \n\n

What are Combination Rescue Inhalers?

• Combination rescue inhalers contain a fast-acting bronchodilator as well as an inhaled corticosteroid (ICS)

• The steroid helps to reduce some of the chronic airway inflammation that is worsening the asthma attack and can help to prevent future attacks

• Examples include budesonide-formoterol and albuterol-budesonide

• Global Initiative for Asthma (GINA), states that combination therapy is now the preferred reliever for adults and adolescents with mild asthma

What are the drawbacks of Combination Rescue Inhalers?

• These inhalers are generally more expensive than just using a SABA inhaler which can be a barrier for some people \n\n

• Improper use can also lead to conditions like thrush due to the addition of the steroid
