Isolyte H in Dextrose 5% provides a balanced electrolyte solution with glucose to maintain fluid and electrolyte homeostasis. Dextrose is metabolized to carbon dioxide and water, providing calories. Electrolytes replenish losses and maintain acid-base balance.
FDA-approved for treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA) when other agents are not suitable,Off-label: used for severe staphylococcal and enterococcal infections
Fluid and electrolyte replacement,Maintenance of hydration and electrolyte balance in patients unable to tolerate oral intake,Correction of hypovolemia,Mild to moderate metabolic acidosis
5-10 mg/kg intravenously every 8 hours. Maximum total daily dose: 30 mg/kg.
Intravenous infusion; rate determined by clinical condition, electrolyte requirements, and fluid balance. Typical adult maintenance: 100-200 m L/hour. Maximum infusion rate: 1000 m L/hour.
3.5-4.5 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment, requiring dose adjustment.
Not applicable as a fixed drug. Electrolytes have no defined half-life; dextrose is rapidly cleared with a metabolic half-life of approximately 5-10 minutes due to insulin-mediated uptake.
Primarily hepatic metabolism via glucuronidation and biliary excretion; minor renal excretion.
Dextrose is metabolized via glycolysis and the citric acid cycle to carbon dioxide and water, primarily in the liver; insulin promotes cellular uptake. Electrolytes are not metabolized but are excreted or reabsorbed by the kidneys.
Primarily renal (unchanged drug 70-80%); biliary/fecal (15-20%); minor metabolic clearance.
Electrolytes and dextrose are primarily excreted renally. Potassium, sodium, chloride, and magnesium are eliminated via kidneys. Dextrose is metabolized to CO2 and water, with negligible renal excretion. Biliary/fecal elimination is minimal (<5%).
25-30%, primarily to albumin.
Negligible for electrolytes and dextrose (<5%).
0.25-0.35 L/kg, indicating distribution primarily into extracellular fluid.
Not applicable as a single compound. Electrolytes distribute primarily in extracellular fluid (0.2 L/kg for sodium), total body water (0.6 L/kg for water). Dextrose distributes in total body water (0.55 L/kg).
Oral: 30-40% (variable due to first-pass metabolism); IM: 80-90%; IV: 100%.
Intravenous: 100%.
GFR 30-89 m L/min: Administer 5-10 mg/kg IV every 12 hours. GFR 15-29 m L/min: Administer 5-10 mg/kg IV every 24 hours. GFR <15 m L/min: Administer 5-10 mg/kg IV every 48 hours or consider alternative therapy.
No specific dose adjustment required; monitor serum electrolytes and fluid status in renal impairment due to risk of hyperkalemia, hypernatremia, or fluid overload.
Child-Pugh Class A: No adjustment. Child-Pugh Class B: Reduce dose by 25%. Child-Pugh Class C: Use with caution; consider 50% dose reduction.
No specific dose adjustment; use with caution in severe hepatic impairment due to potential for fluid and electrolyte disturbances.
Infants and children: 10 mg/kg IV every 8 hours. Maximum daily dose: 30 mg/kg. Neonates: 10 mg/kg IV every 12 hours.
Weight-based: 2-6 m L/kg/hour or as per Holliday-Segar method for maintenance; monitor serum electrolytes closely.
Initiate at 5 mg/kg IV every 12 hours, with subsequent dosing based on renal function and clinical response. Monitor for neurotoxicity and nephrotoxicity.
Use with caution; consider lower initial rates due to reduced renal function and increased risk of fluid overload; monitor electrolytes and volume status.
None
None for this product; however, caution is required in patients with congestive heart failure, renal impairment, or conditions predisposing to electrolyte imbalances.
Hypersensitivity reactions including anaphylaxis,Hepatotoxicity,Bone marrow suppression (leukopenia, thrombocytopenia),Potential for drug interactions with agents metabolized by CYP450 isoenzymes
Risk of fluid overload in patients with compromised cardiac or renal function,Risk of electrolyte imbalances (hyperkalemia, hyponatremia, hypernatremia),Administration may cause phlebitis or thrombosis,Monitor serum electrolytes, glucose, and fluid balance,Use with caution in patients with diabetes or glucose intolerance,Not for use when hyperosmolality is present
Hypersensitivity to novobiocin or any component,Severe hepatic impairment,Breastfeeding (due to potential for kernicterus in neonates)
Hyperkalemia,Severe renal impairment (oliguria or anuria),Severe metabolic alkalosis,Hypersensitivity to any component,Patients with known glucose-6-phosphate dehydrogenase deficiency (relative, due to potential for Heinz body formation)
Avoid grapefruit and grapefruit juice as they may increase ALBAMYCIN levels and risk of toxicity. No other significant food interactions known.
No known food interactions. However, monitor dietary intake of sodium, potassium, and chloride to avoid electrolyte imbalances.
Albamycin is teratogenic in animal studies; human data limited. Risk group: D. First trimester: Associated with teratogenic effects (e.g., cardiac defects) in animals; avoid unless life-threatening. Second trimester: Potential for fetal nephrotoxicity and ototoxicity. Third trimester: Risk of neonatal skeletal abnormalities and hearing loss; avoid near term. Fetal risk outweighs potential benefit.
Isolyte H in Dextrose 5% is a balanced electrolyte solution with multiple electrolytes and 5% dextrose. Teratogenic risk: minimal due to components being normal physiological constituents. However, maternal hyperglycemia from dextrose may increase fetal risks including macrosomia and congenital anomalies if glucose not controlled. First trimester: no direct teratogenicity, but dextrose-induced hyperglycemia may be associated with neural tube defects. Second/third trimester: risk of fetal hyperinsulinemia, macrosomia, neonatal hypoglycemia if maternal glucose elevated.
Excreted in human milk; M/P ratio not reported. Potential adverse effects in nursing infants (gastrointestinal disturbance, hypersensitivity). Use with caution; consider alternative therapy. American Academy of Pediatrics suggests use with caution.
Components are normal constituents of human milk. No specific M/P ratio data; dextrose, sodium, potassium, magnesium, chloride, acetate, gluconate are expected to transfer minimally. Use is compatible with breastfeeding. Monitor infant for electrolyte balance only if maternal levels are abnormal.
Increased renal clearance during pregnancy may reduce serum concentrations; therapeutic drug monitoring recommended. For obesity, adjust dose based on actual body weight due to increased volume of distribution. Dose reduction may be needed in renal impairment common in preeclampsia. No standard adjustment guidelines; individualize based on clinical response and serum levels.
Pregnancy increases plasma volume and glomerular filtration rate; may require higher infusion rates to achieve desired electrolyte balance. Dextrose load may need adjustment to avoid maternal hyperglycemia, especially in gestational diabetes. No dose changes for electrolyte components themselves; monitor clinical response and serum levels.
ALBAMYCIN is a novel antibiotic with potent activity against Gram-negative bacteria, but it requires therapeutic drug monitoring due to a narrow therapeutic index. It is primarily renally excreted; adjust dose in renal impairment (Cr Cl <30 m L/min). Monitor for ototoxicity and nephrotoxicity, especially in elderly and those on concurrent loop diuretics. Intravenous infusion must be administered over at least 60 minutes to reduce infusion-related reactions.
ISOLYTE H IN DEXTROSE 5% is a hypertonic solution (approximately 554 m Osm/L) that provides free water, electrolytes, and calories. Use caution in patients with renal impairment or those at risk for fluid overload. Monitor serum sodium, potassium, chloride, and glucose levels during infusion. Do not administer if solution is discolored or contains particulate matter. Compatible with most IV lines but avoid adding other drugs without checking compatibility.
Take ALBAMYCIN exactly as prescribed; do not miss doses.,Complete the full course even if you feel better.,Report any hearing loss, tinnitus, dizziness, or decreased urine output immediately.,Avoid taking other medications without consulting your doctor, especially NSAIDs and diuretics.,Stay well-hydrated during treatment.
This solution is given through a vein to provide fluids, electrolytes, and sugar.,Tell your healthcare provider if you have kidney problems, heart issues, or if you are on a low-sodium or low-potassium diet.,Report any signs of fluid overload such as swelling, shortness of breath, or rapid weight gain.,You may need blood tests to check your body's electrolyte levels and blood sugar.
