Precautions
In patients with impaired hepatic or renal function, appropriate monitoring is recommended during therapy
If aminoglycoside is used concurrently, especially if high dosages of former are used or if therapy is prolonged, renal function should be monitored because of potential nephrotoxicity and ototoxicity of aminoglycoside antibiotics
Use of antibiotics may promote overgrowth of nonsusceptible organisms, including Gram-positive organisms (Staphylococcus aureus and Streptococcus faecalis) and fungi; take appropriate measures if superinfection occur during therapy
Rare cases of toxic epidermal necrolysis reported in association with therapy in patients undergoing bone marrow transplant with multiple risk factors including sepsis, radiation therapy, and other concomitantly administered drugs associated with toxic epidermal necrolysis
Clostridium difficile–associated diarrhea (CDAD)
Reported with use of nearly all antibacterial agents and may range in severity from mild diarrhea to fatal colitis; treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile
If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued; appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated
Monitoring Parameters
Monitor for signs of anaphylaxis during 1st dose; periodic LFT.
Monitor infusion/injection sites carefully; administer around-the-clock to minimize variations in peak and trough serum levels

Mechanism of Action
Aztreonam inhibits bacterial cell wall synthesis due to its high affinity for penicillin-binding protein 3 (PBP-3) of gm-ve bacteria. It is highly resistant to hydrolysis by many narrow-spectrum β-lactamases. It is also active against most Enterobacteriaceae (including E. coli, Citrobacter, Enterobacter, Klebsiella, Proteus, Providencia, Salmonella, Serratia, Shigella, Yersinia spp. and Morganella morganii).
