Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Dextrose 5% provides a source of calories and fluid for hydration, preventing ketosis by providing a minimal carbohydrate source. Sodium chloride 0.9% supplies electrolytes and maintains osmotic pressure in extracellular fluid.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, causing misreading of m RNA and inhibiting bacterial protein synthesis.
Fluid and electrolyte replacement in patients with isotonic dehydration,Maintenance of hydration and electrolyte balance when oral intake is inadequate,Vehicle for intravenous administration of compatible drugs,Hypovolemia (off-label),Shock (off-label)
Treatment of serious gram-negative bacterial infections (e.g., Pseudomonas aeruginosa, Escherichia coli, Klebsiella species),Used in combination for severe infections such as sepsis, pneumonia, complicated urinary tract infections, and intra-abdominal infections
Intravenous infusion; typical adult dose is 500-1000 m L as a single dose, administered at a rate determined by clinical condition (e.g., 100-200 m L/h for maintenance).
15 mg/kg/day IV divided every 8-12 hours or 15-20 mg/kg IV once daily; typical adult dose: 500-1000 mg IV every 8-12 hours.
Glucose has a plasma half-life of approximately 1.5-2.5 hours in normal individuals, reflecting rapid cellular uptake and metabolism. Sodium and chloride have no definable half-life as they are actively regulated; however, the half-life of infused sodium is approximately 2-4 hours depending on renal function.
The terminal elimination half-life is approximately 2-3 hours in adults with normal renal function. In neonates, it may be prolonged to 4-8 hours. In patients with impaired renal function, half-life can extend to 30-80 hours or more, necessitating dose adjustment based on creatinine clearance.
Dextrose is metabolized via glycolysis and the Krebs cycle to carbon dioxide and water; insulin-dependent. Sodium chloride is not metabolized; excreted renally.
Amikacin is minimally metabolized; primarily eliminated unchanged by glomerular filtration.
Glucose is completely metabolized to CO2 and water; renal excretion of unchanged glucose is negligible (<1%) in normoglycemic patients. Sodium and chloride are primarily excreted renally (90-95% of infused load) with small fecal and sweat losses. In dextrose 5% and sodium chloride 0.9%, both components are eliminated renally; the dextrose is metabolized, not excreted unchanged.
Amikacin is eliminated primarily by glomerular filtration. Approximately 94-98% of an administered dose is excreted unchanged in the urine within 24 hours in patients with normal renal function. Less than 1% is excreted in bile or feces.
Dextrose: negligible (<1%) binding to plasma proteins. Sodium: not protein-bound. Chloride: not protein-bound.
Amikacin has low protein binding, ranging from 0-11%. It binds primarily to albumin, but due to low binding, protein binding alterations do not significantly impact pharmacokinetics.
Dextrose: Vd approximately 0.15-0.25 L/kg (primarily extracellular fluid). Sodium and chloride: Vd approximately 0.25 L/kg (distributes into extracellular space). Total body water distribution occurs only if free water is present.
The volume of distribution is approximately 0.25-0.4 L/kg in adults. It reflects distribution primarily into extracellular fluid. The Vd is increased in conditions such as edema, ascites, and sepsis, and is decreased in dehydration. In neonates, the Vd is larger (0.5-0.6 L/kg) due to higher extracellular fluid volume.
Intravenous: 100% bioavailability. Not administered orally for these purposes; if ingested, dextrose undergoes first-pass metabolism (oral bioavailability ~50-60% due to hepatic extraction) and sodium chloride is fully absorbed.
Intramuscular: Nearly complete, with bioavailability >90%. Oral: Not bioavailable due to negligible gastrointestinal absorption (<1%). Intravenous: 100%.
Not applicable; contains sodium chloride and dextrose; monitor serum sodium and glucose in renal impairment. For GFR <30 m L/min, use with caution due to risk of hypernatremia and fluid overload.
Cr Cl 30-60 m L/min: administer every 12-24 hours; Cr Cl 15-29 m L/min: administer every 24-48 hours; Cr Cl <15 m L/min: administer every 48-72 hours. Use therapeutic drug monitoring.

Neonates: 15-20 mg/kg IV every 24 hours; Infants and children: 15-20 mg/kg IV every 8-24 hours depending on age and renal function. Not to exceed 1.5 g/day.
Use with caution; lower infusion rates recommended due to reduced renal function and higher risk of fluid overload and electrolyte disturbances; monitor serum sodium and glucose closely.
Reduce initial dose based on renal function; monitor serum creatinine and drug levels; typical starting dose: 7.5 mg/kg IV every 24 hours adjusted for Cr Cl.
No FDA black box warnings.
Aminoglycosides, including amikacin, are associated with nephrotoxicity and ototoxicity (both auditory and vestibular), which can occur even at therapeutic doses. Risk is increased with prolonged use, higher doses, renal impairment, and concurrent use of other nephrotoxic or ototoxic drugs. Monitoring of renal function and serum drug levels is essential.
Hyperglycemia in patients with diabetes or stress-induced hyperglycemia,Fluid overload in patients with heart failure, renal impairment, or edematous states,Hyponatremia (especially in children, elderly, and post-operative patients),Hypernatremia with excessive administration,Osmotic demyelination syndrome with rapid correction of hyponatremia,Phlebitis or extravasation at infusion site
Neurotoxicity (including ototoxicity and nephrotoxicity) may occur. Risk of neuromuscular blockade, especially in patients with neuromuscular disorders or receiving anesthetics. Monitor renal function, audiometric tests, and serum drug concentrations. Use with caution in elderly, dehydrated, or renally impaired patients. Avoid concomitant use of other nephrotoxic or ototoxic agents.
Hyperglycemia (severe) when dextrose use is inadvisable,Hypernatremia,Acute intracranial hemorrhage (if using hypotonic solutions, but not applicable here),Severe renal impairment (oliguria/anuria) with volume overload risk,Patients with known hypersensitivity to dextrose or corn-based products
Hypersensitivity to amikacin or any aminoglycoside; history of aminoglycoside-associated ototoxicity or nephrotoxicity; myasthenia gravis (risk of neuromuscular blockade).
No direct food interactions. However, monitor total sodium and glucose intake if patient is on a restricted diet for diabetes or hypertension.
No significant food interactions. Maintain adequate hydration unless contraindicated. No specific dietary restrictions.
Dextrose and sodium chloride are physiologic substances. No teratogenic risk at standard doses. Excessive sodium may cause maternal hypernatremia with fetal effects indirectly. No trimester-specific risks.
Amikacin is an aminoglycoside antibiotic. There are no adequate and well-controlled studies in pregnant women. Aminoglycosides can cause fetal harm when administered to a pregnant woman. There is a potential for fetal ototoxicity and nephrotoxicity. First trimester: Risks unknown but avoid if possible. Second/Third trimester: Use only if clearly needed and if benefit outweighs risk; associated with irreversible bilateral congenital deafness when administered during pregnancy.
Exogenous dextrose and sodium chloride are normal blood constituents; negligible transfer into milk. M/P ratio not applicable. Compatible with breastfeeding.
Amikacin is excreted in human milk in low concentrations. The M/P ratio is approximately 0.15-0.5. Based on limited data, the dose to the infant is estimated to be <1% of maternal dose. Use with caution in nursing mothers; monitor infant for diarrhea, candidiasis, and potential allergic reactions. Consider the benefits of breast-feeding and the importance of amikacin to the mother.
No specific dose adjustments for dextrose 5% and sodium chloride 0.9%; use standard dosing. Monitor for gestational hyperglycemia and edema; adjust rate based on clinical status.
Pregnancy may alter pharmacokinetics due to increased volume of distribution and renal blood flow. However, specific dosing adjustments for amikacin in pregnancy are not well established. Monitor serum drug concentrations (peak and trough) to guide dosing, especially in patients with renal impairment or prolonged therapy. Use standard dosing with careful monitoring.
Must confirm IV access patency before infusion; hypertonic 0.9% Na Cl may cause phlebitis. Use with caution in heart failure, renal impairment, or hypernatremia. Monitor serum glucose and sodium levels during prolonged administration. Not suitable for dilution of incompatible medications.
Avoid concomitant use with other nephrotoxic or ototoxic drugs (e.g., loop diuretics, vancomycin). Monitor peak (25-35 mcg/m L) and trough (<8 mcg/m L) serum levels to guide dosing and reduce toxicity risk. Extended-interval (once-daily) dosing is preferred in many patients; adjust for renal function using ideal body weight. In obese patients, dose based on adjusted body weight. Rapid infusion can cause neuromuscular blockade; use with caution in myasthenia gravis or concurrent neuromuscular blocking agents.

"Lithium cation may increase the excretion rate of Sodium chloride which could result in a lower serum level and potentially a reduction in efficacy."
"The risk or severity of adverse effects can be increased when Sodium chloride is combined with Tolvaptan."
"Amikacin, an aminoglycoside antibiotic, may competitively inhibit the renal tubular secretion and potentially reduce the clearance of masoprocol, a dicarboxylic acid derivative used as a chemotherapeutic agent. This interaction could lead to increased systemic exposure to masoprocol, elevating the risk of dose-dependent toxicities such as severe enteritis, myelosuppression, and hepatotoxicity. Given the narrow therapeutic index of masoprocol, even modest elevations in serum levels may result in clinically significant adverse outcomes."
"Amikacin, an aminoglycoside antibiotic, may competitively inhibit the tubular secretion of mycophenolic acid (MPA) in the renal proximal tubules, leading to reduced renal clearance of MPA. This interaction can result in elevated serum levels of MPA, increasing the risk of dose-related toxicities such as bone marrow suppression (leukopenia, thrombocytopenia), gastrointestinal disturbances, and increased susceptibility to infections. Patients receiving this combination should be closely monitored for signs of MPA toxicity, especially those with pre-existing renal impairment."
"Coadministration of Metocurine, a nondepolarizing neuromuscular blocking agent, with Amikacin, an aminoglycoside antibiotic, may result in enhanced and prolonged neuromuscular blockade. Aminoglycosides can impair acetylcholine release from presynaptic nerve terminals and reduce postsynaptic sensitivity, synergistically augmenting the effects of nondepolarizing agents. This interaction can lead to excessive muscle relaxation, including respiratory muscle paralysis, increasing the risk of apnea and postoperative respiratory depression."
