Description

11 DESCRIPTION Potassium Chloride is a white granular powder. It is soluble in water and slightly soluble in alcohol. Chemically, Potassium Chloride is K-Cl with a molecular mass of 74.55. Each pouch of light orange mottled powder contains 1.5 g of potassium chloride, USP, which is equivalent to potassium 20 mEq and chloride 20 mEq and the following inactive ingredients: FD&C Yellow #6, sucralose, silicon dioxide, maltodextrin, citric acid, and orange flavor.

What Is Potassium Chloride Used For?

1 INDICATIONS AND USAGE Potassium Chloride is indicated for the treatment and prophylaxis of hypokalemia with or without metabolic alkalosis, in patients for whom dietary management with potassium-rich foods or diuretic dose reduction is insufficient. Potassium Chloride is a potassium salt indicated for the treatment and prophylaxis of hypokalemia with or without metabolic alkalosis, in patients for whom dietary management with potassium-rich foods or diuretic dose reduction is insufficient.

Dosage and Administration

2 DOSAGE AND ADMINISTRATION Dilute prior to administration. ( 2.1 , 5.1 ) Monitor serum potassium and adjust dosage accordingly ( 2.2 , 2.3 ) If serum potassium concentration is <2.5 mEq/L, use intravenous potassium instead of oral supplementation ( 2.1 ) Treatment of hypokalemia:

  • Adults: Initial doses range from 40-100 mEq/day in 2-5 divided doses: limit doses to 40 mEq per dose. Total daily dose should not exceed 200 mEq ( 2.2 )
  • Pediatric patients aged birth to 16 years old: 2-4 mEq/kg/day in divided doses; not to exceed 1 mEq/kg as a single dose or 40 mEq whichever is lower; if deficits are severe or ongoing losses are great, consider intravenous therapy. Total daily dose should not exceed 100 mEq ( 2.3 ) Maintenance or Prophylaxis of hypokalemia:
  • Adults: Typical dose is 20 mEq per day ( 2.2 )
  • Pediatric patients aged birth to 16 years old: typical dose is 1 mEq/kg/day. Do not to exceed 3 mEq/kg/day ( 2.3 ) 2.1 Administration and Monitoring Monitoring Monitor serum potassium and adjust dosages accordingly. For treatment of hypokalemia, monitor potassium levels daily or more often depending on the severity of hypokalemia until they return to normal. Monitor potassium levels monthly to biannually for maintenance or prophylaxis. The treatment of potassium depletion, particularly in the presence of cardiac disease, renal disease, or acidosis requires careful attention to acid-base balance, volume status, electrolytes, including magnesium, sodium, chloride, phosphate, and calcium, electrocardiograms and the clinical status of the patient. Correct volume status, acid-base balance and electrolyte deficits as appropriate. Administration Dilute the contents of 1 pouch of potassium chloride for oral solution in at least 4 ounces of cold water [see Warnings and Precautions (5.1) ]. Take with meals or immediately after eating. If serum potassium concentration is <2.5 mEq/L, use intravenous potassium instead of oral supplementation. 2.2 Adult Dosing Treatment of hypokalemia: Daily dose range from 40 to 100 mEq. Give in 2 to 5 divided doses: limit doses to 40 mEq per dose. The total daily dose should not exceed 200 mEq in a 24 hour period. Maintenance or Prophylaxis, Typical dose is 20 mEq per day. Individualize dose based upon serum potassium levels. Studies support the use of potassium replacement in digitalis toxicity. When alkalosis is present, normokalemia and hyperkalemia may obscure a total potassium deficit. The advisability of use of potassium replacement in the setting of hyperkalemia is uncertain. 2.3 Pediatric Dosing Treatment of hypokalemia: Pediatric patients aged birth to 16 years old: The initial dose is 2 to 4 mEq/kg/day in divided doses; do not exceed as a single dose 1 mEq/kg or 40 mEq, whichever is lower; maximum daily doses should not exceed 100 mEq. If deficits are severe or ongoing losses are great, consider intravenous therapy. Maintenance or Prophylaxis Pediatric patients aged birth to 16 years old: Typical dose is 1...

    • Side Effects (Adverse Reactions)

    6 ADVERSE REACTIONS The most common adverse reactions to oral potassium salts are nausea, vomiting, flatulence, abdominal pain/discomfort, and diarrhea.

    Drug Interactions

    7 DRUG INTERACTIONS

  • Potassium sparing diuretics: Avoid concomitant use ( 7.1 )
  • Renin-angiotensin-aldosterone inhibitors: Monitor for hyperkalemia ( 7.2 )
  • Nonsteroidal Anti-Inflammatory drugs: Monitor for hyperkalemia ( 7.3 ) 7.1 Potassium-Sparing Diuretics Use with potassium-sparing diuretics can produce severe hyperkalemia. Avoid concomitant use. 7.2 Renin-Angiotensin-Aldosterone System Inhibitors Drugs that inhibit the renin-angiotensin-aldosterone system (RAAS) including angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), spironolactone, eplerenone, or aliskiren produce potassium retention by inhibiting aldosterone production. Closely monitor potassium in patients receiving concomitant RAAS therapy. 7.3 Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) NSAIDS may produce potassium retention by reducing renal synthesis of prostaglandin E and impairing the renin-angiotensin system. Closely monitor potassium in patients on concomitant NSAIDs.

    • Contraindications

    4 CONTRAINDICATIONS Potassium chloride is contraindicated in patients on potassium sparing diuretics.

  • Concomitant use with potassium sparing diuretics. ( 4 )

    • Pregnancy and Breastfeeding

    8.1 Pregnancy There are no human data related to use of Potassium Chloride during pregnancy, and animal studies have not been conducted. Potassium supplementation that does not lead to hyperkalemia is not expected to cause fetal harm. The background risk for major birth defects and miscarriage in 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 2-4% and 15-20%, respectively.

    Overdosage

    10 OVERDOSAGE 10.1 Symptoms The administration of oral potassium salts to persons with normal excretory mechanisms for potassium rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired or if potassium is administered too rapidly potentially fatal hyperkalemia can result. Hyperkalemia is usually asymptomatic and may be manifested only by an increased serum potassium concentration (6.5–8.0 mEq/L) and characteristic electrocardiographic changes (peaking of T-waves, loss of P-waves, depression of S-T segment, and prolongation of the QT-interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9–12 mEq/L). 10.2 Treatment Treatment measures for hyperkalemia include the following: 1. Monitor closely for arrhythmias and electrolyte changes. 2. Eliminate foods and medications containing potassium and of any agents with potassium-sparing properties such as potassium-sparing diuretics, ARBS, ACE inhibitors, NSAIDS, certain nutritional supplements and many others. 3. Administer intravenous calcium gluconate if the patient is at no risk or low risk of developing digitalis toxicity. 4. Administer intravenously 300 to 500 mL/hr of 10% dextrose solution containing 10 to 20 units of crystalline insulin per 1000 mL. 5. Correct acidosis, if present, with intravenous sodium bicarbonate. 6. Use exchange resins, hemodialysis, or peritoneal dialysis. In patients who have been stabilized on digitalis, too rapid a lowering of the serum potassium concentration can produce digitalis toxicity.
