( 5.4 , 5.5 , 5.6 , 5.7 , 5.8 , 5.9 )
5.1Serious Risk with Concomitant Use with Ceftriaxone Precipitation of ceftriaxone-calcium can occur when ceftriaxone is mixed with calcium-containing solutions, such as Lactated Ringer’s Injection in the same intravenous administration line. Deaths have occurred in neonates (28 days of age or younger) who received concomitant intravenous calcium-containing solutions with ceftriaxone resulting from calcium-ceftriaxone precipitates in the lungs and kidneys, even when separate infusion lines were used. Lactated Ringer’s Injection is contraindicated in neonates who receive ceftriaxone [see Contraindications (4) , Use in Specific Populations (8.4) ].
However, in patients older than 28 days, ceftriaxone and Lactated Ringer’s Injection may be administered sequentially if the infusion lines are thoroughly flushed between infusions with a compatible fluid .
5.2Air Embolism Cases of air embolism have been reported with pressurized administration of intravenous fluids. Air embolism may result in stroke, organ ischemia and/or infarction, and death. Use a non-vented infusion set or close the vent on a vented set and use a dedicated line without any connections.
If administration is controlled by a pumping device, care must be taken to discontinue the pumping action before the container is empty. Pressure infusion is not recommended to increase flow rates, but if necessary, ensure all air is removed from the bag before infusion. Refrain from applying excessive pressure (>300mmHg) causing distortion to the container such as wringing or twisting.
Such handling could result in breakage of the container [see Dosage and Administration (2.3) ] .
5.3Hypersensitivity Reactions Hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with Lactated Ringer’s Injection . Stop the Lactated Ringer’s Injection infusion immediately and treat patient accordingly if signs or symptoms of a hypersensitivity reaction develop. Initiate appropriate treatment as clinically indicated.
5.4Potassium Imbalances Hyperkalemia Potassium-containing solutions, including Lactated Ringer’s Injection , may increase the risk of hyperkalemia. This risk is increased in patients predisposed to hyperkalemia including those with severe renal impairment, acute dehydration, extensive tissue injury or burns, heart failure, or in those using concomitant drugs that are associated with hyperkalemia. Avoid use of Lactated Ringer’s Injection in patients with, or at increased risk for, hyperkalemia.
If use cannot be avoided in these patients, closely monitor serum potassium concentrations. Hypokalemia The potassium concentration in Lactated Ringer’s Injection is similar to the concentration in plasma. It is insufficient to normalize the serum potassium in patients with severe hypokalemia.

7 DRUG INTERACTIONS Drugs that Affect Electrolyte and/or Fluid Balance : Avoid concomitant use. If concomitant use cannot be avoided, closely monitor electrolyte concentrations and fluid balance. ( 7.1 ) Lithium : Avoid concomitant use.
If concomitant use is unavoidable monitor serum lithium concentrations more frequently. ( 7.2 ) Digoxin : Consider reducing the volume or rate of Lactated Ringer’s Injection due to the increased risk of digoxin toxicity with calcium-containing solutions. ( 7.3 ) Drugs with pH-Dependent Renal Elimination : Renal clearance of acidic drugs may be increased.
In contrast, renal clearance of alkaline drugs may be decreased. ( 7.4 )
7.1Drugs that Affect Electrolyte and/or Fluid Balance Hyperkalemia Administration of Lactated Ringer’s Injection to patients concomitantly treated or recently treated with drugs that are associated with hyperkalemia increases the risk of severe and potentially fatal hyperkalemia, especially in the presence of other hyperkalemia risk factors . Avoid use of Lactated Ringer’s Injection in patients receiving drugs that are associated with hyperkalemia (e.g., potassium-sparing diuretics, ACE inhibitors, angiotensin II receptor antagonists, or calcineurin inhibitors).
If concomitant use cannot be avoided, closely monitor serum potassium concentrations during concomitant use [see Warnings and Precautions (5.4) ]. Hyponatremia Administration of Lactated Ringer’s Injection to patients treated concomitantly with drugs associated with hyponatremia may increase the risk of developing hyponatremia. These drugs include diuretics and those that cause SIADH (e.g., arginine vasopressin analogs, certain antiepileptic, psychotropic, or cytotoxic drugs).
Avoid use of Lactated Ringer’s Injection in patients receiving such drugs. If use cannot be avoided, closely monitor serum sodium concentrations during concomitant use [see Warnings and Precautions (5.5) ] . Hypercalcemia Avoid the use of Lactated Ringer’s Injection in patients treated with thiazide diuretics or vitamin D because these drugs can increase the risk of hypercalcemia.
If use cannot be avoided, closely monitor serum calcium concentrations during concomitant use [see Warnings and Precautions (5.6) ]. Hypernatremia and Fluid Retention Administration of Lactated Ringer’s Injection to patients treated concomitantly with drugs associated with sodium and fluid retention (e.g., corticosteroids or corticotropin) may increase the risk of hypernatremia and volume overload. Avoid use of Lactated Ringer’s Injection in patients receiving such drugs.
If use cannot be avoided, closely monitor serum electrolytes, fluid balance, and acid-base balance during concomitant use.
7.2Lithium Renal sodium and lithium clearance may be increased during concomitant use of Lactated Ringer’s Injection and lithium and may result in decreased lithium concentrations. Avoid use of Lactated Ringer’s Injection in patients receiving lithium. If use cannot be avoided, increase the frequency of monitoring of serum lithium concentrations during concomitant use.
7.3Digoxin Administration of calcium via use of Lactated Ringer’s Injection may increase digoxin’s effects and lead to digoxin toxicity including serious or fatal cardiac arrhythmias. In digoxin-treated patients, consider reducing the volume and/or rate of Lactated Ringer’s Injection administration .
7.4Drugs with pH-Dependent Renal Elimination Due to the alkalinizing action of lactate (formation of bicarbonate), Lactated Ringer’s Injection may interfere with the elimination of drugs with pH-dependent renal elimination. Renal clearance of alkaline drugs may be decreased. In contrast, renal clearance of acidic drugs may be increased.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Closely monitor plasma electrolyte concentrations in young pediatric patients with immature kidney function. ( 8.4 ). Geriatric patients are more likely to have decreased renal function.
Consider monitoring renal function and starting the infusion at the low end of the dosing range. ( 8.5 ) Avoid in patients with severe renal impairment. ( 8.6 ) Patients with severe hepatic impairment may have impaired lactate metabolism.
Closely monitor serum lactate levels and acid-base status. ( 8.7 )
8.1Pregnancy Risk Summary Lactated Ringer’s as a source of water and electrolytes has been used for decades during labor and delivery. Although there are no reports of use of Lactated Ringer’s in other stages of pregnancy, exposure during pregnancy is not expected to cause major birth defects, miscarriage, or adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted with this drug .
The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
8.2Lactation Risk Summary Lactated Ringer’s as a source of water and electrolytes has been used for decades and is not expected to cause harm to a breastfed infant. There are no data on the presence of Lactated Ringer’s Injection in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Lactated Ringer’s Injection and any potential adverse effects on the breastfed infant from Lactated Ringer’s Injection or from the underlying maternal condition.
8.4Pediatric Use Lactated Ringer’s Injection is contraindicated in neonates (28 days of age or younger) who are receiving ceftriaxone due to reported deaths that occurred when neonates received ceftriaxone and intravenous calcium-containing solutions concomitantly [see Warnings and Precautions (5.1) ]. The safety and effectiveness of Lactated Ringer’s Injection for use as a source of water and electrolytes or as an alkalinizing agent have been established in pediatric patients of all ages, including neonates. Closely monitor plasma electrolyte concentrations in young pediatric patients with immature kidney function who may have decreased ability to maintain fluid and electrolyte balance [see Warnings and Precautions ( 5.4 , 5.5 , 5.8 , 5.9 )].
Administration of a lactate-containing intravenous solution, including Lactated Ringer’s Injection to pediatric patients should account for liver and kidney maturation (the kidney function affects the biotransformation and renal excretion of lactate) [see Warnings and Precautions (5.9) ].
8.5Geriatric Use Geriatric patients treated with Lactated Ringer’s Injection are at increased risk of developing electrolyte imbalances. Lactated Ringer’s Injection is substantially excreted by the kidney, and the risk of adverse reactions to Lactated Ringer’s Injection may be greater in patients with renal impairment than in patients with normal renal function. Because geriatric patients are more likely to have decreased renal function, consider monitoring renal function in geriatric patients and consider starting the infusion at the low end of the dosing range.
8.6Renal Impairment Administration of Lactated Ringer’s Injection to patients with or at risk of severe renal impairment, may result in hyperkalemia and/or fluid overload [see Warnings and Precautions ( 5.4 , 5.7 , 5.9 )]. Avoid Lactated Ringer’s Injection in patients with severe renal impairment. If use cannot be avoided in such patients, monitor for development of these adverse reactions.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Lactated Ringer’s Injection is a source of water, electrolytes, and produces an alkalinizing effect. Sodium, the major cation of the extracellular fluid, functions primarily in the control of water distribution, fluid balance, and osmotic pressure of body fluids. Sodium is also associated with chloride and bicarbonate in the regulation of the acid-base equilibrium of body fluid.
Potassium, the principal cation of intracellular fluid, participates in carbohydrate utilization and protein synthesis and is critical in the regulation of nerve conduction and muscle contraction, particularly in the heart. Chloride, the major extracellular anion, closely follows the metabolism of sodium, and changes in the acid-base balance of the body are reflected by changes in the chloride concentration. Calcium, an important cation, provides the framework of bones and teeth in the form of calcium phosphate and calcium carbonate.
In the ionized form, calcium is essential for the functional mechanism of the clotting of blood, normal cardiac function, and regulation of neuromuscular irritability. Sodium lactate provides sodium and lactate ions. The lactate anion is in equilibrium with pyruvate and has an alkalinizing effect resulting from simultaneous removal by the liver of lactate and hydrogen ions.
The sodium ion combines with bicarbonate ion produced from carbon dioxide of the body and thus retains bicarbonate to combat metabolic acidosis (bicarbonate deficiency).
12.2Pharmacodynamics The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of Lactated Ringer’s Injection have not been fully characterized.
12.3Pharmacokinetics Elimination Metabolism/Excretion Potassium: Normally about 80 to 90% of the potassium intake is excreted in the urine; the remainder is excreted in feces and to a smaller extent, in perspiration. Sodium and Chloride: The distribution and excretion of sodium (Na + ) and chloride (Cl − ) are largely under the control of the kidney which maintains a balance between intake and output. Lactate: In the liver, lactate is metabolized to carbon dioxide and water by oxidative metabolism and consumption of hydrogen cations.
