Cefepime
Cefepime (Maxipime) is a powerful, broad-spectrum intravenous antibiotic commonly used in the inpatient and intensive care unit (ICU) settings to treat a myriad of infections. As a fourth generation cephalosporin, cefepime covers many gram positive and gram negative organisms (including Pseudomonas). As an intensivist, I use this antibiotic for everything from hospital acquired pneumonia and complicated urinary infections to empiric coverage for neutropenic fever. 💉👨🏽⚕️ . During my ICU fellowship, there were several instances where I encountered cefepime-related encephalopathy. Unlike more clear-cut drug-related side effects, this is a diagnosis of exclusion that can be confounded by the clinical situation itself (ie, overwhelming sepsis can certainly cause altered mentation). Nevertheless, it's prudent to always consider narrowing a patient's antibiotic regimen when appropriate! 😷👍 . It's important to understand that cefepime does not provide coverage for methicillin resistant Staphylococcus aureus (MRSA), Enterococci, and anaerobic organisms. This is why I often combine it with vancomycin (covers MRSA) and metronidazole (covers anaerobes) or replace cefepime with agents like meropenem or pipercillin/tazobactam. 🤓🏥 from @rishimd
