# Genixim (Cefixime) ## Overview Genixim is a broad-spectrum, third-generation oral cephalosporin antibiotic. It acts by inhibiting bacterial cell wall synthesis through binding to penicillin-binding proteins (PBPs), leading to bacterial cell lysis. It is stable against many beta-lactamases. ## Primary Indications * Acute bronchitis (acute exacerbation). * Otitis media. * Pharyngitis and tonsillitis. * Uncomplicated urinary tract infections (UTIs). * Uncomplicated gonorrhea (cervical/urethral). ## Adult Dosing * **General infections:** 400 mg daily, administered as a single dose or divided into 200 mg every 12 hours. * **Uncomplicated gonorrhea:** 400 mg as a single oral dose. * **Maximum dose:** 400 mg per day. ## Pediatric Dosing * **Children (>6 months):** 8 mg/kg/day, administered as a single dose or divided into 4 mg/kg every 12 hours. * **Maximum dose:** 400 mg per day. * *Note: Safety and efficacy have not been established in infants under 6 months.* ## Dose Adjustments * **Renal Impairment (CrCl 21–60 mL/min):** Reduce dose by 25% (or 300 mg daily). * **Renal Impairment (CrCl <20 mL/min):** Reduce dose by 50% (or 200 mg daily). * **Hemodialysis:** No supplemental dose required; standard renal-adjusted dosing applies. ## Contraindications * Known hypersensitivity to cefixime or other cephalosporin antibiotics. * History of severe allergic reactions (e.g., anaphylaxis) to penicillins or other beta-lactams (potential for cross-reactivity). ## Adverse Effects * **Common:** Diarrhea (frequent), abdominal pain, nausea, dyspepsia, and flatulence. * **Serious:** *Clostridioides difficile*-associated diarrhea (CDAD), severe cutaneous adverse reactions (SCARs like Stevens-Johnson syndrome), and anaphylaxis. ## Key Drug Interactions * **Warfarin/Anticoagulants:** May enhance the effects of anticoagulants; monitor International Normalized Ratio (INR). * **Probenecid:** May increase serum concentrations of cefixime by inhibiting renal tubular secretion. ## Monitoring * Monitor for signs of hypersensitivity reactions during initial doses. * Assess renal function in patients with chronic kidney disease. * Monitor for persistent diarrhea, which may indicate *C. difficile* infection. ## Clinical Pearls * Cefixime has poor activity against *Staphylococcus aureus* and enterococci. * Diarrhea is a dose-dependent side effect; taking the medication with food may mitigate gastrointestinal distress. * The suspension form and tablet form are not necessarily bioequivalent; verify formulation before prescribing. * Local resistance patterns vary significantly; consult institutional antibiograms for empirical therapy decisions. *** **Educational Disclaimer:** This information is for educational purposes only.
