POTASSIUM CHLORIDE IN LACTATED RINGERS AND DEXTROSE

Intravenous solution with potassium chloride (I.V. solutions with KCl) is a sterile and nonpyrogenic solution in water for injection. This solution is for administration by intravenous infusion only. See Table 1 below for summary of content and characteristics of this solution. Table 1 COMPOSITION (g/L) Calculated Osmolarity (mOsmol/L) Potassium Chloride in Lactated Ringer's and 5% Dextrose Injection, USP mEq Potassium Added Size (mL) Dextrose, Hydrous Potassium Chloride Sodium Chloride Sodium Lactate, Anhydrous Calcium Chloride Dihydrate 20 mEq 1000 50 1.79 6 3.1 0.2 563 pH Approx. Ionic Concentrations (mEq/L) Approx. kcal/L Calcium (Ca++) Sodium (Na+) Potassium (K+) Chloride (Cl-) Lactate 4.9 (3.5 to 6.5) 2.7 130 24 129 28 179 May contain HCl for pH adjustment. The solution contains no bacteriostat, antimicrobial agent or added buffer and each is intended only for use as a single-dose injection. When smaller doses are required the unused portion should be discarded. This solution is a parenteral fluid, nutrient and/or electrolyte replenisher. Dextrose, USP is chemically designated D-glucose, monohydrate (C 6 H 12 O 6 • H 2 O), a hexose sugar freely soluble in water. It has the following structural formula: Potassium Chloride, USP is chemically designated KCl, a white granular powder freely soluble in water. Sodium Chloride, USP is chemically designated NaCl, a white crystalline powder freely soluble in water. Calcium Chloride, USP is chemically designated calcium chloride dihydrate (CaCl 2 • 2H 2 O), white fragments or granules freely soluble in water. Sodium Lactate, USP is chemically designated monosodium lactate [CH 3 CH(OH)COONa], a 50% aqueous solution miscible in water. It has the following structural formula: Water for Injection, USP is chemically designated H 2 0. The flexible plastic container is fabricated from a specially formulated non-plasticized, film containing polypropylene and thermoplastic elastomers ( free flex ® bag). Water can permeate from inside the container into the overwrap but not in amounts sufficient to affect the solution significantly. Solutions in contact with the plastic container may leach out certain chemical components from the plastic in very small amounts; however, biological testing was supportive of the safety of the plastic container materials. Exposure to temperatures above 25°C/77°F during transport and storage will lead to minor losses in the moisture content. Higher temperatures lead to greater losses. It is unlikely that these minor losses will lead to clinically significant changes within the expiration period. Dextrose Structural Formula Calcium Chloride Structural Formula

This solution is indicated in patients requiring parenteral administration of potassium chloride and the replacement of extracellular losses of fluids and electrolytes with minimal carbohydrate calories.

This solution should be administered only by intravenous infusion and as directed by the physician. The dose and rate of injection are dependent upon the age, weight and clinical condition of the patient. If the serum potassium level is greater than 2.5 mEq/liter, potassium should be given at a rate not to exceed 10 mEq/hour in a concentration less than 30 mEq/liter. Somewhat faster rates and greater concentrations (usually up to 40 mEq/liter) of potassium may be indicated in patients with more severe potassium deficiency. The total 24-hour dose should not generally exceed 200 mEq of potassium. As reported in the literature, the dosage and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low birth weight infants, because of the increased risk of hyperglycemia/hypoglycemia. Drug Interactions Additives may be incompatible. Consult with pharmacist, if available. When introducing additives, use aseptic technique, mix thoroughly and do not store. The presence of calcium limits their compatibility with certain drugs that form precipitates of calcium salts, and also prohibits their simultaneous infusion through the same administration set as blood because of the likelihood of coagulation. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. See PRECAUTIONS .

Solutions containing potassium chloride are contraindicated in diseases where high potassium levels may be encountered. Solutions containing lactate are NOT FOR USE IN THE TREATMENT OF LACTIC ACIDOSIS.

Reactions which may occur because of the solutions or 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. 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. Nausea, vomiting, abdominal pain and diarrhea have been reported with potassium therapy. The signs and symptoms of potassium intoxication include paresthesias of the extremities, flaccid paralysis, listlessness, mental confusion, weakness and heaviness of the legs, hypotension, cardiac arrhythmias, heart block, electrocardiographic abnormalities such as disappearance of P waves, spreading and slurring of the QRS complex with development of a biphasic curve and cardiac arrest. Potassium-containing solutions are intrinsically irritating to tissues. Therefore, extreme care should be taken to avoid perivascular infiltration. Local tissue necrosis and subsequent sloughing may result if extravasation occurs. Chemical phlebitis and venospasm have also been reported. Should perivascular infiltration occur, I.V. administration at that site should be discontinued at once. Local infiltration of the affected area with procaine hydrochloride, 1%, to which hyaluronidase may be added, will often reduce venospasm and dilute the potassium remaining in the tissues locally. Local application of heat may also be helpful. To report SUSPECTED ADVERSE REACTIONS, contact Fresenius Kabi USA, LLC at 1-800-551-7176 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
