# Tabgenixim (Cefixime)
## Overview
Tabgenixim is a brand/generic alternative name for **Cefixime**, a third-generation cephalosporin antibiotic. It possesses broad-spectrum activity against Gram-negative organisms and stable activity against beta-lactamases compared to earlier generations.
## Primary Indications
* Uncomplicated urinary tract infections (UTIs)
* Otitis media
* Pharyngitis and tonsillitis
* Acute bronchitis/exacerbations of chronic bronchitis
* Uncomplicated gonorrhea (cervical, urethral, rectal)
## Adult Dosing
* **General infections:** 400 mg once daily or 200 mg every 12 hours.
* **Uncomplicated gonorrhea:** 800 mg as a single oral dose (note: dual therapy with ceftriaxone injection is often preferred by current CDC guidelines; confirm local institutional protocol regarding monotherapy).
## Pediatric Dosing
* **Children ≥ 6 months:** 8 mg/kg/day administered as a single dose or divided into two doses (4 mg/kg every 12 hours).
* **Maximum Dose:** 400 mg per day.
* **Otitis Media:** 8 mg/kg/day once daily or divided BID.
## Dose Adjustments
* **Renal Impairment (CrCl 21–60 mL/min):** Administer 75% of the standard dose.
* **Renal Impairment (CrCl < 20 mL/min):** Administer 50% of the standard dose.
* **Hemodialysis/CAPD:** No supplemental dose required; remain at 50% of standard dose.
## Contraindications
* Known hypersensitivity to cefixime or other cephalosporins.
* History of severe allergic reaction (e.g., anaphylaxis) to penicillins or other beta-lactams due to potential cross-reactivity.
## Adverse Effects
* **Common:** Diarrhea (often dose-related), abdominal pain, nausea, dyspepsia, and flatulence.
* **Serious:** *Clostridioides difficile*-associated diarrhea (CDAD), hypersensitivity reactions (rash, urticaria, pruritus), and rare instances of Stevens-Johnson syndrome or toxic epidermal necrolysis.
## Key Drug Interactions
* **Anticoagulants:** May enhance the anticoagulant effect of warfarin (monitor INR).
* **Probenecid:** Can increase serum concentrations of cefixime by reducing renal tubular secretion.
* **Carbamazepine:** May increase serum levels of carbamazepine, necessitating monitoring for toxicity.
## Monitoring
* **Clinical:** Monitor for resolution of infection symptoms.
* **Safety:** Monitor for signs of severe diarrhea or signs of hypersensitivity (rash).
* **Renal:** In cases of prolonged therapy, monitor renal function periodically.
## Clinical Pearls
* **Administration:** May be administered with or without food.
* **Dosing Form:** Oral suspension should be shaken well.
* **Spectrum:** While a broad-spectrum agent, it is generally ineffective against *Staphylococcus aureus* and has variable activity against *Streptococcus pneumoniae*. It is not indicated for empiric coverage when these pathogens are suspected.
* **Stability:** Once reconstituted, the oral suspension is generally stable for 14 days at room temperature; follow specific manufacturer labels.
