Key takeaways
Budesonide (Pulmicort Flexhaler) and albuterol (ProAir HFA, Ventolin HFA) are both inhaled medications used to manage asthma, but they belong to different medication classes and serve distinct purposes. Budesonide is an inhaled corticosteroid (ICS) used for the maintenance treatment of asthma in people aged 6 years and older. It works by reducing inflammation in the lungs and is typically taken twice daily. Albuterol, on the other hand, is a short-acting beta agonist (SABA) used as a rescue inhaler to quickly relieve sudden wheezing or shortness of breath in people aged 4 years and older. It is taken every 4 to 6 hours as needed. Budesonide is not used for immediate relief during an asthma attack, while albuterol provides quick relief within minutes. Budesonide is available in two strengths (90 mcg and 180 mcg per inhalation), whereas albuterol delivers 90 mcg per inhalation. Common side effects of budesonide include symptoms of the common cold and sore throat, while albuterol may cause sore throat and runny nose. Even though it's an inhaler, albuterol can interact with some oral medications, including beta blockers and digoxin.
