Ceftazidime Injection

• Type: Antibiotic injection

• Drug Class: Third-generation cephalosporin antibiotic

• Form: Sterile powder for reconstitution, given intravenously (IV) or intramuscularly (IM)

How It Works

• Ceftazidime kills bacteria by blocking bacterial cell wall synthesis.

• This weakens the bacterial cell wall, causing it to burst and leading to bacterial death.

• It is particularly effective against gram-negative bacteria, including Pseudomonas aeruginosa, a frequent cause of hospital-acquired infections.

Common Uses

Doctors prescribe ceftazidime for serious bacterial infections such as:

• Hospital-acquired pneumonia (including ventilator-associated pneumonia)

• Sepsis (bloodstream infections)

• Febrile neutropenia (fever in patients with low white blood cell count)

• Complicated urinary tract infections (UTIs)

• Complicated skin and soft tissue infections

• Bone and joint infections

• Bacterial meningitis (especially caused by gram-negative bacteria)

• Intra-abdominal infections (often used with metronidazole)

Advantages

• Strong activity against Pseudomonas aeruginosa

• Good penetration into cerebrospinal fluid (CSF), making it useful in meningitis

• Suitable for use in both community and hospital settings

• Well-studied and widely available

Possible Side Effects

• Pain, swelling, or redness at injection site

• Diarrhea, nausea, vomiting

• Headache or fever

• Rash, itching, or other mild allergic reactions

• Changes in kidney or liver function (seen in blood tests)

• Rare: severe allergic reaction (anaphylaxis)

• Very rare: seizures (especially in patients with kidney problems if dose is not adjusted)

Precautions

• Kidney function must be monitored — dose adjustment is needed in kidney impairment

• Caution in people with a history of penicillin or cephalosporin allergy

• Long-term or inappropriate use can lead to superinfections (such as Clostridium difficile diarrhea)

• Should always be administered under supervision of healthcare professionals
