Potassium Chloride In Sodium Chloride Injection, Usp

Potassium Chloride in Sodium Chloride Injection, USP is indicated as a source of water and electrolytes.

Potassium Chloride in Sodium Chloride Injection, USP is contraindicated in patients with:

• Known hypersensitivity to potassium chloride and/or sodium chloride (see WARNINGS).
• Clinically significant hyperkalemia (see WARNINGS).

The following adverse reactions associated with the use of Potassium Chloride in Sodium Chloride Injection, USP were identified in clinical trials or postmarketing reports. Because postmarketing reactions were reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency, reliably, or to establish a causal relationship to drug exposure.

• General disorders and administration site conditions: Chills, and infusion site pain. Hypersensitivity reactions: generalized papules and erythema, rash, fever, vomiting, hypertension, tachycardia.
• Metabolism and nutrition disorders: Hyperkalemia, hyponatremia, hypernatremia, hyperchloremia acidosis, fluid overload.
• Cardiac disorders: Cardiac arrest as a manifestation of rapid intravenous administration and/or of hyperkalemia.
• Nervous System Disorders: Hyponatremic encephalopathy.

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.

20 mEq/L Potassium Chloride in 0.45% Sodium Chloride Injection, USP is supplied in 1000 mL single-dose flexible plastic containers (NDC 0409-9257-39) (NDC 0990-9257-39).

ICU Medical is transitioning NDC codes from the "0409" to a "0990" labeler code. Both NDC codes are expected to be in the market for a period of time.

Potassium Chloride in Sodium Chloride Injection, USP is a sterile, nonpyrogenic, solution for fluid and electrolyte replenishment in a single dose container for intravenous administration. It contains no antimicrobial agents. Composition, osmolarity, pH and ionic concentration are shown in Table 1.

The flexible plastic container is fabricated from a specially formulated polyvinyl chloride (PL 146 Plastic). The amount of water that can permeate from inside the container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the plastic container can leach out certain of its chemical components in very small amounts within the expiration period. However, the safety of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers.

Renal sodium and lithium clearance may be increased during administration of Potassium Chloride in Sodium Chloride Injection, USP and result in decreased lithium concentrations. Monitor serum lithium concentrations during concomitant use.

There are no adequate and well controlled studies from the use of Potassium Chloride in Sodium Chloride Injection, USP in pregnant or lactating women and animal reproduction studies have not been conducted with this drug. Therefore, it is also not known whether Potassium Chloride in Sodium Chloride Injection, USP can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Potassium Chloride in Sodium Chloride Injection, USP should be given to a pregnant woman only if the potential benefit justifies the potential risk to the fetus.

An increased infusion rate of Potassium Chloride in Sodium Chloride Injection, USP can cause:

• hyperkalemia, manifestations may include disturbances in cardiac conduction and arrhythmias, including bradycardia, heart block, asystole, ventricular tachycardia, ventricular fibrillation.

The presence of any ECG findings that are suspected to be caused by hyperkalemia should be considered a medical emergency.

If hyperkalemia is present or suspected, discontinue the infusion immediately and institute close ECG, laboratory and other monitoring and, as necessary, corrective therapy to reduce serum potassium concentrations.

Muscle weakness (up to and including muscular and respiratory paralysis, paresthesia of extremities) may occur as a complication of hyperkalemia.

• hyponatremia, manifestations may include seizures, coma, cerebral edema and death).
• hypernatremia, especially in patients with severe renal impairment.
• hypotension.
• gastrointestinal symptoms (ileus, nausea, vomiting, abdominal pain).
• fluid overload (which can lead to central and/or peripheral edema). See WARNINGS and ADVERSE REACTIONS.

When assessing an overdose, any additives in the solution must also be considered. The effects of an overdose may require immediate medical attention and treatment.

Interventions include discontinuation of Potassium Chloride in Sodium Chloride Injection, USP administration, dose reduction, and other measures as indicated for the specific clinical constellation (e.g., monitoring of fluid balance, electrolyte concentrations and acid base balance).

Potassium-containing solutions, including Potassium Chloride in Sodium Chloride Injection, USP may increase the risk of hyperkalemia. Hyperkalemia can be asymptomatic and manifest only by increased serum potassium concentrations and/or characteristic electrocardiographic (ECG) changes. Cardiac conduction disorders (including complete heart block) and other cardiac arrhythmias, some fatal, can develop at any time during hyperkalemia. Continuous electrocardiogram (ECG) monitoring may be necessary to aid in the detection of cardiac arrhythmias due to hyperkalemia (see ADVERSE REACTIONS).

To avoid life threatening hyperkalemia, do not administer Potassium Chloride in Sodium Chloride Injection, USP as an intravenous push (i.e., intravenous injection manually with a syringe connected to the intravenous access) without a quantitative infusion device.

Patients at increased risk of developing hyperkalemia and cardiac arrhythmias include those:

• with conditions predisposing to hyperkalemia and/or associated with increased sensitivity to potassium, such as patients with severe renal impairment, acute dehydration, extensive tissue injury or burns, certain cardiac disorders such as congestive heart failure or atrioventricular (AV) block (especially if they receive digoxin).
• who are at risk of experiencing hyperosmolality, acidosis, or undergoing correction of alkalosis (conditions associated with a shift of potassium from intracellular to extracellular space).
• treated concurrently or recently with agents or products that can cause or increase the risk of hyperkalemia (see DRUG INTERACTIONS).
• with cardiac arrhythmias.

Avoid use of Potassium Chloride in Sodium Chloride Injection, USP in patients with, or at risk for, hyperkalemia. If use cannot be avoided, use a product with a low amount of potassium chloride, infuse slowly and monitor serum potassium concentrations and ECGs.

Potassium Chloride in Sodium Chloride Injection, USP may cause hyponatremia.

Hyponatremia can lead to acute hyponatremic encephalopathy characterized by headache, nausea, seizures, lethargy, and vomiting. Patients with brain edema are at particular risk of severe, irreversible and life-threatening brain injury.

The risk of hospital-acquired hyponatremia is increased in patients with cardiac or pulmonary failure, and in patients with non-osmotic vasopressin release (including SIADH) treated with high volume of hypotonic Potassium Chloride in Sodium Chloride Injection, USP.

The risk for hyponatremia is increased in pediatric patients, elderly patients, postoperative patients, those with psychogenic polydipsia, and in patients treated with medications that increase the risk of hyponatremia (such as diuretics, certain antiepileptic and psychotropic medications). See DRUG INTERACTIONS.

Patients at increased risk for developing complications of hyponatremia such as hyponatremic encephalopathy, include pediatric patients, women (in particular, premenopausal women), patients with hypoxemia, and patients with underlying central nervous system disease. Avoid Potassium Chloride in Sodium Chloride Injection, USP in patients with or at risk for hyponatremia. If use cannot be avoided, monitor serum sodium concentrations.

Rapid correction of hyponatremia is potentially dangerous with risk of serious neurologic complications. Brain adaptations reducing risk of cerebral edema make the brain vulnerable to injury when chronic hyponatremia is too rapidly corrected, which is known as osmotic demyelination syndrome (ODS). To avoid complications, monitor serum sodium and chloride concentrations, fluid status, acid-base balance, and signs of neurologic complications.

Geriatric patients are at increased risk of developing electrolyte imbalances. Potassium Chloride in Sodium Chloride Injection, USP is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Therefore, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Consider monitoring renal function in elderly patients.

The use of Potassium Chloride in Sodium Chloride Injection, USP in pediatric patients is based on clinical practice. (See DOSAGE AND ADMINISTRATION). Safety and effectiveness of Potassium Chloride in Sodium Chloride Injection, USP in pediatric patients have not been established by adequate and well-controlled studies.

Pediatric patients are at increased risk of developing hyponatremia as well as for developing encephalopathy as a complication of hyponatremia (see WARNINGS).

Depending on the volume and rate of infusion, and the patient's underlying clinical condition, the intravenous administration of Potassium Chloride in Sodium Chloride Injection, USP can cause electrolyte disturbances such as overhydration/hypervolemia and congested states including central (e.g., pulmonary edema) and peripheral edema.

Avoid Potassium Chloride in Sodium Chloride Injection, USP in patients with or at risk for fluid and/or solute overloading. If use cannot be avoided, monitor fluid balance, electrolyte concentrations and acid base balance as needed and especially during prolonged use.

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Potassium Chloride in Sodium Chloride Injection, USP is administered to a nursing mother.

Hypersensitivity and infusion reactions, including anaphylaxis and chills, have been reported with products containing potassium chloride and sodium chloride. Stop the infusion immediately if signs or symptoms of a hypersensitivity or infusion reaction develops. Appropriate therapeutic countermeasures must be instituted as clinically indicated.

The choice of the specific potassium chloride and sodium chloride formulation, dosage, volume, rate and duration of administration is dependent upon the age, weight and clinical and metabolic condition of the patient and concomitant therapy, and administration should be determined by a physician experienced in intravenous fluid therapy.

Additional electrolyte supplementation may be indicated according to the clinical needs of the patient. Additives can be introduced to the container; however, some additives may be incompatible. Evaluate all additions to the plastic container for compatibility and stability of the resulting preparation. Consult with a pharmacist, if available.

If, in the informed judgment of the physician, it is deemed advisable to introduce additives, use aseptic technique. After addition, if there is a discoloration and/or the appearance of precipitates, insoluble complexes or crystals, do not use. Mix thoroughly when additives have been introduced. Do not store solutions containing additives. Discard any unused portion.

Rapid correction of hyponatremia and hypernatremia is potentially dangerous (risk of serious neurologic complications). To avoid complications such as osmotic demyelination syndrome (ODS) during administration, follow the important administration instructions, monitor serum sodium and chloride concentrations, fluid status, acid-base balance, and signs of neurologic complications.
