Key takeaways
Formoterol (Perforomist) and albuterol (ProAir HFA, Ventolin HFA, and others) are both bronchodilators used to help with breathing problems, but they work differently and have important differences. Formoterol is a long-acting beta-agonist (LABA) used for long-term control of chronic obstructive pulmonary disease (COPD) and is not used for asthma or sudden breathing problems. It is inhaled using a nebulizer twice daily. Albuterol, on the other hand, is a short-acting beta-agonist (SABA) used every 4 to 6 hours as needed for sudden wheezing or shortness of breath caused by conditions like asthma and COPD. It can also be used to prevent exercise-induced asthma. Both medications are available as a brand and a lower-cost generic. Common side effects of formoterol include diarrhea and nausea, while albuterol may cause sore throat and throat irritation. Both medications can affect your heart rate and blood pressure.
