1-2 g IV every 8 hours; maximum 12 g/day. For severe infections, 2 g every 8 hours.
Intravenous infusion; dosing based on patient's fluid and electrolyte needs. Typical adult dose: 500-1000 m L per hour as needed for volume replacement; adjust rate based on clinical response and serum electrolyte monitoring.
Terminal elimination half-life ~0.8-1.4 hours in adults with normal renal function. Prolonged to 4-8 hours in severe renal impairment (Cr Cl <20 m L/min).
Not applicable as a fixed half-life; components distribute and equilibrate rapidly. For administered volume, intravascular half-life is 20-30 minutes due to redistribution to interstitial space. Electrolyte half-lives: sodium ~8-12 hours, chloride ~8-12 hours, potassium ~12-24 hours, calcium ~24-48 hours, magnesium ~24-48 hours.
Partially metabolized in the liver to desacetylcefotaxime (active metabolite), primarily excreted unchanged via kidneys.
Acetate is metabolized via acetyl-Co A in the tricarboxylic acid cycle, yielding bicarbonate; primary sites include liver and skeletal muscle.
Renal: ~80-90% unchanged via glomerular filtration and tubular secretion. Biliary: <5%. Fecal: minimal.
Acetated Ringer's solution components are excreted primarily renally: water (100% via kidneys), sodium (90-95% renal, 5-10% sweat/feces), chloride (90-95% renal), acetate (metabolized to bicarbonate, then CO2 excreted via lungs; <5% renal), potassium (80-90% renal, 10-20% feces), calcium (98% renal reabsorption, <2% fecal), magnesium (70% renal, 30% fecal).
~35%, primarily to albumin.
Calcium: ~40% bound to albumin; magnesium: ~30% bound to albumin; other components (sodium, potassium, chloride, acetate) have negligible protein binding (<5%).
0.25-0.5 L/kg in adults; higher in neonates (0.5-0.7 L/kg). Reflects distribution into extracellular fluid.
Not a single value for all components. Water distributes into total body water (0.6 L/kg), sodium and chloride primarily into extracellular fluid (0.2 L/kg), potassium into intracellular fluid (0.4 L/kg), calcium and magnesium into bone and cells (Vd ~0.5-0.8 L/kg).
IM: ~100%.
Intravenous: 100% (only route administered). Oral: not applicable; not administered orally.
Cr Cl 50-80 m L/min: 1-2 g every 8-12 hours; Cr Cl 20-49 m L/min: 1-2 g every 12-24 hours; Cr Cl 5-19 m L/min: 1-2 g every 24 hours; Cr Cl <5 m L/min: 1-2 g every 48 hours. Hemodialysis: 1-2 g after each dialysis session.
No specific GFR-based dose adjustment required; however, use with caution in renal impairment due to risk of fluid overload and electrolyte imbalances. Monitor serum potassium and renal function.
No adjustment required for Child-Pugh A. Child-Pugh B/C: No specific guidelines; monitor for adverse effects.
No specific Child-Pugh dose adjustment; use with caution in severe hepatic impairment due to potential altered lactate metabolism. Monitor electrolytes and acid-base status.
Neonates 0-7 days: 50 mg/kg IV every 12 hours; Neonates 8-28 days: 50 mg/kg IV every 8 hours; Infants/children 1 month-12 years: 50 mg/kg IV every 8 hours (max 2 g/dose); Children >12 years: same as adult.
Weight-based dosing: 20-30 m L/kg as a bolus over 30-60 minutes for volume expansion; maintenance: adjust based on fluid deficit and ongoing losses. Maximum rate and volume vary by clinical condition.
No specific dose adjustment based on age alone; adjust dose based on renal function as per renal adjustment guidelines.
Consider reduced initial volume and slower infusion rate due to decreased cardiovascular reserve and higher risk of fluid overload. Monitor closely for signs of heart failure and electrolyte disturbances.
No FDA black box warning.
Not available; no FDA boxed warning.
Hypersensitivity reactions including anaphylaxis, Clostridioides difficile-associated diarrhea, seizures (especially in renal impairment), superinfection, prolonged use may lead to bacterial resistance, caution in patients with history of gastrointestinal disease (colitis), and renal impairment requires dose adjustment.
Monitor serum electrolytes and acid-base status; avoid in patients with severe renal impairment or alkalosis; caution in heart failure, pulmonary edema, and conditions causing sodium retention.
Hypersensitivity to cefotaxime or any cephalosporin, history of severe immediate hypersensitivity reaction to penicillins or other beta-lactams.
Hypernatremia, hyperkalemia, hypercalcemia, metabolic alkalosis, severe renal failure with oliguria/anuria, and known hypersensitivity to any component.
Avoid alcohol and alcohol-containing foods or medications (e.g., mouthwash, cough syrups) during treatment and for 72 hours after stopping due to risk of disulfiram-like reaction. No other food interactions known.
No specific food interactions. However, dietary intake of sodium and potassium should be considered in patients with electrolyte imbalances or renal impairment.
Cefotaxime is classified as FDA Pregnancy Category B. Animal studies have not demonstrated teratogenic effects. There are no adequate and well-controlled studies in pregnant women. Risks to the fetus are considered low; however, cefotaxime should be used during pregnancy only if clearly needed.
No fetal risks identified; acetated Ringer's solution is isotonic and used for fluid and electrolyte replenishment. No teratogenic effects reported in any trimester.
Cefotaxime is excreted into human breast milk in low concentrations. The M/P ratio has not been established. It is generally considered compatible with breastfeeding due to low oral bioavailability in infants. Caution is advised with monitoring for potential effects on infant gastrointestinal flora.
Considered safe during breastfeeding; components (sodium, chloride, potassium, calcium, acetate) are normal physiological constituents. M/P ratio not applicable.
Pregnancy-induced physiological changes (increased plasma volume, enhanced renal clearance) may necessitate higher doses of cefotaxime to achieve therapeutic concentrations. Dose adjustments should be based on clinical response and therapeutic drug monitoring if available. Standard dosing regimens are typically effective, but consider upward adjustment in severe infections.
No dose adjustments required due to pregnancy; pharmacokinetics of electrolytes and water unchanged; adjust dosing based on clinical status and losses.
Claforan (cefotaxime) is a third-generation cephalosporin with broad-spectrum gram-negative coverage, including many Enterobacteriaceae. In sodium chloride 0.9% (NS), it is stable for 24 hours at room temperature. Administer over 30 minutes for intermittent infusion. Note: Cross-allergenicity with penicillins occurs in ~10% of patients; use caution. Monitor renal function in elderly and high-dose therapy. For surgical prophylaxis, give within 60 minutes before incision. May cause a disulfiram-like reaction with alcohol due to the NMTT side chain. Adjust dose in severe renal impairment (Cr Cl <20 m L/min: decrease dose or extend interval).
Acetated Ringer's is an isotonic crystalloid containing acetate as a bicarbonate precursor; it does not require hepatic metabolism for alkalinization, unlike lactate, making it preferable in patients with hepatic impairment or lactic acidosis. Monitor serum electrolytes and acid-base status during infusion, especially in renal impairment. Do not administer through same IV line with blood products due to risk of hemolysis from calcium content. Avoid use in metabolic alkalosis.
