Ceftazidime Injection

• Type: Antibiotic injection

• Drug Class: Third-generation cephalosporin

• Form: Powder or solution for intravenous (IV) or intramuscular (IM) use

How It Works

• Ceftazidime stops bacteria from building their cell wall, causing them to weaken and die.

• It is especially good at fighting gram-negative bacteria, including Pseudomonas aeruginosa, a serious hospital-acquired pathogen.

Common Uses

Ceftazidime is prescribed for serious infections such as:

• Pneumonia (especially hospital-acquired)

• Sepsis (bloodstream infection)

• Complicated urinary tract infections

• Skin and soft tissue infections

• Bone and joint infections

• Meningitis (brain/spinal cord infection caused by susceptible bacteria)

• Intra-abdominal infections (often combined with other antibiotics)

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

Advantages

• Very effective against Pseudomonas and many other gram-negative bacteria

• Good penetration into cerebrospinal fluid, useful for meningitis

• Can be used alone or in combination with other antibiotics for severe infections

Possible Side Effects

• Pain or swelling at injection site

• Diarrhea, nausea, vomiting

• Mild allergic reactions (rash, itching)

• Changes in liver or kidney function tests

• Rare: severe allergic reaction (anaphylaxis)

• Very rare: seizures (especially if kidney function is poor and dose is not adjusted)

Precautions

• Kidney function monitoring is important, as dose adjustments are required in kidney disease

• Caution if allergic to penicillins or other cephalosporins

• Prolonged use can cause superinfections like fungal overgrowth or C. difficile diarrhea

• Should be given under medical supervision
