General information
Ceftriaxone is a broad-spectrum antibiotic effective in treating a variety of bacterial infections. It is frequently prescribed to treat infections of the renal, urinary, gastro-intestinal and respiratory tract, as well as meningitis, sepsis, gonorrhoea and certain infections of the bone, joints, skin, soft tissue and wounds caused by organisms that are susceptible to ceftriaxone.
It is important to note that this medication is only effective against bacterial infections - if your infection is the result of a viral or fungal infection, it will be ineffective.
Persons who are allergic to penicillin should take ceftriaxone with caution. Although it is not a penicillin, cross-sensitivity - meaning that you may also be allergic to this drug - may occur.
How does Ceftriaxone work?
Ceftriaxone weakens the bacterial cell wall and allows water to enter the cell, causing cells to burst.
