Ceftavit injection is a combination of two medications, ceftriaxone, and tazobactam. Ceftriaxone is a cephalosporin antibiotic that is used to treat bacterial infections that work by stopping the growth of the bacteria. At the same time, tazobactam is a beta-lactamase inhibitor that prevents antibacterial resistance and allows the antibiotic to take effect. As a combination medication, it is used to treat a wide range of bacterial infections across the body.
