Contact your doctor if:

  • you develop a rash - this could mean that you have an allergic reaction to aztreonam
  • you have difficulty breathing (bronchospasm) immediately after inhalation.  Bronchospasm is a potential side effect with inhalation therapies such as this.

When aztreonam is inhaled, it enters the lungs and come in contact with the P. aeruginosa bacteria that are present. It binds to certain P. aeruginosa proteins and interferes with the development of the bacterial cell wall causing the cell wall to break and killing the bacteria. By decreasing the number of P. aeruginosa bacteria living in the lungs, lung infection is reduced and respiratory symptoms and lung function are improved.
