This page contains brief details about the drug , it's indication, dosage & administaration, mechanism of action, related brands with strength, warnings and common side effects.

Background and Date of Approval

Ceftizoxime is an amino thiazolyl cephalosporin with an extended spectrum of activity against many gram-negative, nosocomially acquired pathogens. It is a 'third generation' cephalosporin. 

Mechanism of Action of undefined

Ceftizoxime interferes with bacterial cell wall synthesis by inhibiting the formation of peptidoglycan, a crucial cell wall component. This weakens the cell wall's integrity, leading to bacterial cell lysis and death. This medication primarily targets Gram-negative bacteria and is effective against many bacterial species.

Uses of undefined

Ceftizoxime, an antibiotic from the cephalosporin class, is used to treat a range of bacterial infections. Its versatility extends to conditions such as urinary tract infections, respiratory tract infections, skin and soft tissue infections, intra-abdominal infections, gynecological infections, sepsis, and surgical prophylaxis.

undefined Drug administaration and Dosage available

Ceftizoxime can be administered through two main routes: intravenous (IV), where the medication is directly infused into a vein for rapid effect, and intramuscular (IM), involving injection into a muscle for slower absorption. The choice between these routes depends on the severity of the infection and the patient's condition, as determined by healthcare professionals.

Warnings, Precautions and Side Effects of undefined


Ceftizoxime can cause severe allergic reactions, including anaphylaxis. The use of antibiotics like this medication can lead to the development of infections caused by antibiotic-resistant bacteria. This medication can disrupt the normal gut flora and lead to CDAD, a severe bacterial infection. If persistent or severe diarrhea occurs during or after treatment, it could indicate CDAD. This medication can interfere with certain glucose tests, potentially leading to false-positive results. Be cautious about using this medication for viral infections or non-bacterial conditions.


If any signs of allergic reactions like rash, itching, swelling, or difficulty breathing occur, seek medical attention immediately.  Using ceftizoxime responsibly, as prescribed, and only for bacterial infections is essential to mitigate this risk of infections caused by antibiotic-resistant bacteria.  If you have diabetes or are undergoing glucose testing, inform your healthcare provider. Unnecessary use can contribute to the development of antibiotic-resistant organisms.

Side Effects

Ceftizoxime can cause a range of side effects. Common side effects include gastrointestinal disturbances like nausea, vomiting, diarrhea, and skin reactions such as rash and itching. Injection site discomfort can also occur. Serious but rare side effects encompass severe allergic reactions, including anaphylaxis, requiring immediate medical attention. Additionally, persistent and severe diarrhea might indicate Clostridium difficile-associated diarrhea (CDAD), a bacterial infection requiring medical intervention. Fever and liver enzyme elevation has been reported. Consulting a healthcare provider is recommended if any side effects are severe, worsen, or cause concern. 

Word Of Advice

Individuals with known allergies to cephalosporin antibiotics or penicillins must exercise caution due to the potential for allergic reactions. Before starting ceftizoxime, give a complete medical history, including kidney disorders, gastrointestinal conditions like colitis, liver problems, bleeding disorders, and diabetes, to the doctor. Special attention is needed for pediatric and older adult patients, as dosages might require adjustment based on age-related factors. 

Those with lung conditions or bleeding disorders require close attention. Prolonged or inappropriate antibiotic use can lead to antibiotic-resistant organisms' development, so use it only as the doctor prescribes. Individuals with impaired renal function require close monitoring, and caution should be exercised in immunosuppressed patients. Individuals should for check regularly the signs of allergic reactions, bleeding issues, or changes in glucose test results. Sticking to the complete course of treatment, even if symptoms improve, is important. Maintaining a open communication with healthcare providers and adhering to their guidance is important for safety.
