Aztreonam injection is a medication used for the treatment of a number of bacterial infections, such as bladder infections, lower respiratory tract infections, and skin infections. The antibiotic, which is available by prescription, is injected into a vein or a muscle every 6 to 12 hours. It works by preventing bacteria from growing and multiplying. Diarrhea, nausea, and vomiting are possible side effects.
Aztreonam injection (Azactam®) is a prescription antibiotic approved to treat a wide variety of infections, including infections of the urinary tract, lower respiratory tract, skin, abdomen (stomach), and pelvis. It is also used to manage infections that occur after surgery. It belongs to a class of antibiotics called monobactams.
Aztreonam injection is only effective against infections that are caused by bacteria classified as Gram-negative bacteria. Gram-negative bacteria include Escherichia coli (E. coli), Pseudomonas aeruginosa, Klebsiella, and several others.
The antibiotic contained in this medicine is also available in an inhaled form -- Aztreonam for inhalation (Cayston®). This form is approved to treat people with cystic fibrosis who have a chronic lung infection due to the bacterium Pseudomonas aeruginosa.
