Cefepime Injection

• Type: Antibiotic injection

• Drug Class: Fourth-generation cephalosporin antibiotic

• Form: Injectable powder or solution, given intravenously (IV) or sometimes intramuscularly (IM)

How It Works

• Cefepime works by inhibiting bacterial cell wall synthesis.

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

• Being a fourth-generation cephalosporin, it has broad-spectrum activity and is especially effective against gram-negative bacteria, including some resistant strains.

Common Uses

Cefepime is typically used for serious infections, such as:

• Hospital-acquired pneumonia

• Sepsis (bloodstream infections)

• Complicated urinary tract infections (UTIs)

• Complicated intra-abdominal infections (usually with another antibiotic like metronidazole)

• Skin and soft tissue infections

• Febrile neutropenia (fever with very low white blood cell count, often in cancer patients)

Advantages

• Broad coverage against both gram-positive and gram-negative bacteria

• Effective against Pseudomonas aeruginosa, a common and difficult-to-treat hospital-acquired pathogen

• More stable against some beta-lactamase enzymes compared to earlier cephalosporins

Possible Side Effects

• Pain, redness, or swelling at injection site

• Diarrhea, nausea, vomiting

• Rash, itching, or mild allergic reactions

• Headache or fever

• Changes in liver or kidney function tests

• Rare but serious: severe allergic reaction (anaphylaxis), seizures (especially in patients with kidney impairment if dose is not adjusted)

Precautions

• Kidney function must be monitored, and the dose adjusted if kidneys are not working well

• People allergic to penicillins or other cephalosporins should use with caution

• Prolonged use may cause superinfections like Clostridium difficile-associated diarrhea

• Should be given under medical supervision, usually in a hospital setting
