This product is intended for intravenous administration in a single dose container. The formulas of the active ingredients are: Ingredients Molecular Formula Molecular Weight Sodium Chloride USP NaCl 58.44 Sodium Lactate CH 3 CH(OH)COONa 112.06 Potassium Chloride USP KCl 74.55 Calcium Chloride Dihydrate USP CaCl 2 •2H 2 O 147.02 Not made with natural rubber latex, PVC or DEHP. The plastic container is made from a multilayered film specifically developed for parenteral drugs. The solution contact layer is a rubberized copolymer of ethylene and propylene. The container is nontoxic and biologically inert. The container-solution unit is a closed system and is not dependent upon entry of external air during administration. The container is overwrapped to provide protection from the physical environment and to provide an additional moisture barrier when necessary. Addition of medication should be accomplished using complete aseptic technique. The closure system has two ports; the one for the administration set has a tamper evident foil cover and the other is a medication addition site. Refer to the Directions for Use of the container.

This solution is indicated for use in adults and pediatric patients as a source of electrolytes and water for hydration.

This solution is for intravenous use only. Dosage is to be directed by a physician and is dependent upon age, weight, clinical condition of the patient and laboratory determinations. Frequent laboratory determinations and clinical evaluation are essential to monitor changes in blood glucose and electrolyte concentrations, and fluid and electrolyte balance during prolonged parenteral therapy. Fluid administration should be based on calculated maintenance or replacement fluid requirements for each patient. The presence of calcium ions in this solution should be considered when phosphate is present in additive solutions, in order to avoid precipitation. Some additives may be incompatible. Consult with pharmacist. When introducing additives, use aseptic techniques. Mix thoroughly. Do not store. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Ceftriaxone must not be administered simultaneously with calcium-containing intravenous solutions such as Lactated Ringer’s Injection USP via a Y-site. However, in patients other than neonates, ceftriaxone and Lactated Ringer’s Injection USP may be administered sequentially if the infusion lines are thoroughly flushed between infusions with a compatible fluid [see Contraindications, Warnings, Drug Interactions, Pediatric Use ].

The use of Lactated Ringer’s Injection USP is contraindicated in neonates (28 days of age or younger) receiving concomitant treatment with ceftriaxone, even if separate infusion lines are used, due to the risk of fatal ceftriaxone-calcium salt precipitation in the neonate’s bloodstream [see Warnings, Drug Interactions, Pediatric Use ]. This solution is contraindicated where the administration of sodium, potassium, calcium, lactate, or chloride could be clinically detrimental. Lactate administration is contraindicated in severe metabolic acidosis or alkalosis, and in severe liver disease or anoxic states which affect lactate metabolism.

Allergic reactions or anaphylactoid symptoms such as localized or generalized urticaria and pruritus; periorbital, facial, and/or laryngeal edema; coughing, sneezing, and/or difficulty with breathing have been reported during administration of Lactated Ringer's Injection USP. The reporting frequency of these signs and symptoms is higher in women during pregnancy. Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation and hypervolemia. Symptoms may result from an excess or deficit of one or more of the ions present in the solution; therefore, frequent monitoring of electrolyte levels is essential. Hypernatremia may be associated with edema and exacerbation of congestive heart failure due to the retention of water, resulting in an expanded extracellular fluid volume. Reactions reported with the use of potassium-containing solutions include nausea, vomiting, abdominal pain and diarrhea. The signs and symptoms of potassium intoxication include paresthesias of the extremities, areflexia, muscular or respiratory paralysis, mental confusion, weakness, hypotension, cardiac arrhythmias, heart block, electrocardiographic abnormalities and cardiac arrest. Potassium deficits result in disruption of neuromuscular function, and intestinal ileus and dilatation. If infused in large amounts, chloride ions may cause a loss of bicarbonate ions, resulting in an acidifying effect. Abnormally high plasma levels of calcium can result in depression, amnesia, headaches, drowsiness, disorientation, syncope, hallucinations, hypotonia of both skeletal and smooth muscles, dysphagia, arrhythmias and coma. Calcium deficits can result in neuromuscular hyperexcitability, including cramps and convulsions. Although the metabolism of lactate to bicarbonate is a relatively slow process, aggressive administration of sodium lactate may result in metabolic alkalosis. Careful monitoring of blood acid-base balance is essential during the administration of sodium lactate. The physician should also be alert to the possibility of adverse reactions to drug additives. Prescribing information for drug additives to be administered in this manner should be consulted. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures and save the remainder of the fluid for examination if deemed necessary.

Ceftriaxone Precipitation of ceftriaxone-calcium can occur when ceftriaxone is mixed with calcium-containing solutions, such as Lactated Ringer’s Injection USP, in the same intravenous administration line. Do not administer ceftriaxone simultaneously with Lactated Ringer’s Injection USP via a Y-site. However, in patients other than neonates, ceftriaxone and Lactated Ringer’s Injection USP may be administered sequentially if the infusion lines are thoroughly flushed between infusions with a compatible fluid [see Warnings, Dosage and Administration ]. 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 [see Contraindications, Warnings, Pediatric Use, Dosage and Administration ]. Some additives may be incompatible. Consult with pharmacist. When introducing additives, use aseptic techniques. Mix thoroughly. Do not store.
