Learn more about the side effects of Breztri Aerosphere and what you can do to avoid them.

What is Breztri Aerosphere?

Breztri Aerosphere is a combination of budesonide, an inhaled corticosteroid (ICS), glycopyrrolate, a long-acting anticholinergic (sometimes called a long-acting muscarinic antagonist (LAMA)), and formoterol fumarate, a long-acting beta2-agonist ((LABA) bronchodilator).

What is the Breztri Aerosphere used for?

Breztri Aerosphere is used for the maintenance treatment of COPD (chronic obstructive pulmonary disease). COPD is a chronic lung disease that includes chronic bronchitis, emphysema, or both. Breztri aerosphere will reduce the annual rate of moderate or severe COPD exacerbations.

Breztri Aerosphere is not for the treatment of asthma, sudden breathing problems, or acute bronchospasm. It is not a rescue inhaler. LABA medicines increase the risk of hospitalizations and death when used alone. Breztri Aerosphere contains an ICS, an anticholinergic, and a LABA. When an ICS and LABA are used together, there is not a significant risk of hospitalizations and deaths from asthma problems. Breztri Aerosphere can improve lung function and reduce the number of COPD flare-ups you have.

How does Breztri Aerosphere work?

Budesonide reduces irritation and swelling of airways in your lungs. Glycopyrrolate and formoterol help to relax muscles around airways in the lungs, opening them up and allowing you to breathe easier.

  • Upper respiratory tract infection, pneumonia

  • Paradoxical bronchospasm
  • Glaucoma and cataracts, worsening of narrow-angle glaucoma, eye pain
  • Changes in vision such as seeing halos around lights, and blurred vision
  • Worsening of urinary retention
  • Hypokalemia – low levels of potassium may cause symptoms of muscle spasm, muscle weakness, or abnormal heart rhythm
  • Hyperglycemia (high blood sugar levels)
  • Effects on your heart – increased blood pressure, fast heart rate (palpitations), irregular heartbeat, or chest pain
