🩺 Clinical

Label name POTASSIUM CL ER 10 MEQ CAPSULE Ingredient Potassium Chloride
📖 What it is MedlinePlus · NLM

Potassium is essential for the proper functioning of the heart, kidneys, muscles, nerves, and digestive system. Usually the food you eat supplies all of the potassium you need. However, certain diseases (e.g., kidney disease and gastrointestinal disease with vomiting and diarrhea) and drugs, especially diuretics ('water pills'), remove potassium from the body. Potassium supplements are taken to replace potassium losses and prevent potassium deficiency. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Potassium Chloride — the program that covers self-administered drugs. 42 manufacturers.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Potassium Chloride. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

⏱️ Dosage and Administration ~2 min read

2 DOSAGE AND ADMINISTRATION Monitor serum potassium and adjust dosage accordingly. ( 2.1 ) If serum potassium concentration is < 2.5 mEq/L, use intravenous potassium instead of oral supplementation. ( 2.1 ) Treatment of hypokalemia: Adults: Typical doses range from 40 to 100 mEq/day in 2 to 5 divided doses; limit doses to 40 mEq per dose.

( 2.2 ) Pediatric patients: 2 to 4 mEq/kg/day in divided doses not to exceed 1 mEq/kg as a single-dose or 20 mEq, whichever is lower; if deficits are severe or ongoing losses are great, consider intravenous therapy. ( 2.3 ) Maintenance or Prophylaxis of hypokalemia: Adults: Typical dose is 20 mEq per day. ( 2.2 ) Pediatric patients: Typical dose is 1 mEq/kg/day.

( 2.3 )

2.1Administration and Monitoring If serum potassium concentration is < 2.5 mEq/L, use intravenous potassium instead of oral supplementation. Monitoring Monitor serum potassium and adjust dosages accordingly. Monitor serum potassium periodically during maintenance therapy to ensure potassium remains in desired range.

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 Take with meals and with a full glass of water or other liquid.

Do not take on an empty stomach because of the potential for gastric irritation [see Warnings and Precautions (5.1) ] . Patients who have difficulty swallowing capsules may sprinkle the contents of the capsule onto a spoonful of soft food. The soft food, such as applesauce or pudding, should be swallowed immediately without chewing and followed with a glass of water or juice to ensure complete swallowing of the microcapsules.

Do not added to hot foods. Any microcapsule/food mixture should be used immediately and not stored for future use.

2.2Adult Dosing Dosage must be adjusted to the individual needs of each patient. Dosages greater than 40 mEq per day should be divided such that no more than 40 mEq is given in a single-dose. Treatment of hypokalemia: Typical dose range is 40 to 100 mEq per day. Maintenance or Prophylaxis: Typical dose is 20 mEq per day.

2.3Pediatric Dosing Pediatric patients aged birth to 16 years old: Dosage must be adjusted to the individual needs of each patient. Do not exceed as a single-dose 1 mEq/kg or 20 mEq, whichever is lower. Treatment of hypokalemia: The recommended initial dose is 2 to 4 mEq/kg/day in divided doses. If deficits are severe or ongoing losses are great, consider intravenous therapy. Maintenance or Prophylaxis: Typical dose is 1 mEq/kg/day.

💊 Dosage Forms and Strengths 42 words

3 DOSAGE FORMS AND STRENGTHS 750 mg (10 mEq): Blue opaque elongated hard gelatin capsules filled with white to off-white coated pellets and imprinting ‘amneal’ on the cap and ‘542’ on the body with white ink. Extended-release capsules: 750 mg (10 mEq)

⚠️ Warnings and Cautions 116 words

5 WARNINGS AND PRECAUTIONS Gastrointestinal Irritation: Take with meals. ( 5.1 )

5.1Gastrointestinal Adverse Reactions Solid oral dosage forms of potassium chloride can produce ulcerative and/or stenotic lesions of the gastrointestinal tract, particularly if the drug is in contact with the gastrointestinal mucosa for a prolonged period of time. Consider the use of liquid potassium in patients with dysphagia, swallowing disorders, or severe gastrointestinal motility disorders. If severe vomiting, abdominal pain, distention, or gastrointestinal bleeding occurs, discontinue potassium chloride extended-release capsules and consider possibility of ulceration, obstruction or perforation.

Potassium chloride extended-release capsules should not be taken on an empty stomach because of its potential for gastric irritation [see Dosage and Administration (2.1) ] .

🤒 Adverse Reactions 119 words

6 ADVERSE REACTIONS The following adverse reactions have been identified with use of oral potassium salts. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The most common adverse reactions to oral potassium salts are nausea, vomiting, flatulence, abdominal pain/discomfort, and diarrhea.

There have been reports of hyperkalemia and of upper and lower gastrointestinal conditions including, obstruction, bleeding, ulceration, and perforation. Skin rash has been reported rarely. Most common adverse reactions are nausea, vomiting, flatulence, abdominal pain/discomfort, and diarrhea.

🔄 Drug Interactions 123 words

7 DRUG INTERACTIONS Triamterene and amiloride: Concomitant use is contraindicated. ( 7.1 ) Renin-angiotensin-aldosterone inhibitors: Monitor for hyperkalemia. ( 7.2 ) Nonsteroidal Anti-inflammatory drugs (NSAIDs): Monitor for hyperkalemia. ( 7.3 )

7.1Amiloride and Triamterene Use with triamterene or amiloride can produce severe hyperkalemia. Concomitant use is contraindicated [see Contraindications (4) ] .

7.2Renin-Angiotensin-Aldosterone Inhibitors Drugs that inhibit the renin-angiotensin-aldosternone system (RAAS) including angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), spironolactone, eplerenone, or aliskiren produces potassium retention by inhibiting aldosterone production. Closely monitor potassium in patients taking drugs that inhibit RAAS.

7.3Nonsteroidal 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 taking NSAIDs.

👥 Use in Specific Populations ~2 min read

8 USE IN SPECIFIC POPULATIONS Cirrhosis: Initiate therapy at the low end of the dosing range. ( 8.6 ) Renal Impairment: Initiate therapy at the low end of the dosing range. ( 8.7 )

8.1Pregnancy Risk Summary There are no human data related to use of potassium chloride extended-release capsules during pregnancy and animal reproductive 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% to 4% and 15% to 20%, respectively.

8.2Lactation Risk Summary The normal potassium ion content of human milk is about 13 mEq per liter. Since oral potassium becomes part of the body potassium pool, as long as body potassium is not excessive, the contribution of potassium chloride supplementation should have little or no effect on the level in human milk.

8.4Pediatric Use Clinical trial data from published literature have demonstrated the safety and effectiveness of potassium chloride in children with diarrhea and malnutrition from birth to 18 years.

8.5Geriatric Use Clinical studies of potassium chloride did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, 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.

This drug 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. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

8.6Cirrhotics Based on publish literature, the baseline corrected serum concentrations of potassium measured over 3 hours after administration in cirrhotic subjects who received an oral potassium load rose to approximately twice that of normal subjects who received the same load. Patients with cirrhosis should usually be started at the low end of the dosing range, and the serum potassium level should be monitored frequently [see Clinical Pharmacology (12.3) ] .

8.7Renal Impairment Patients with renal impairment have reduced urinary excretion of potassium and are at substantially increased risk of hyperkalemia. Patients with impaired renal function, particularly if the patient is on RAAS inhibitors or nonsteroidal anti-inflammatory drugs, should usually be started at the low end of the dosing range because of the potential for development of hyperkalemia [see Drug Interactions (7.2 , 7.3 ] . The serum potassium level should be monitored frequently.

Renal function should be assessed periodically.

🤰 Pregnancy 99 words

8.1Pregnancy Risk Summary There are no human data related to use of potassium chloride extended-release capsules during pregnancy and animal reproductive 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% to 4% and 15% to 20%, respectively.

🧒 Pediatric Use 29 words

8.4Pediatric Use Clinical trial data from published literature have demonstrated the safety and effectiveness of potassium chloride in children with diarrhea and malnutrition from birth to 18 years.

🧓 Geriatric Use 140 words

8.5Geriatric Use Clinical studies of potassium chloride did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, 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.

This drug 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. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

10 OVERDOSAGE

10.1Symptoms The administration of oral potassium salts to persons with normal excretory mechanisms for potassium rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired, potentially fatal hyperkalemia can result. Hyperkalemia is usually asymptomatic and may be manifested only by an increased serum potassium concentration (6.5 mEq/L to 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 mEq/L to 12 mEq/L).

10.2Treatment Treatment measures for hyperkalemia include the following: 1. Monitor closely for arrhythmias and electrolyte changes. 2.

Eliminate foods and medications containing potassium and 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 300 mL/hr to 500 mL/hr of 10% dextrose solution containing 10 units to 20 units of crystalline insulin per 1,000 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. The extended-release feature means that absorption and toxic effects may be delayed for hours. Consider standard measures to remove any unabsorbed drug.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The potassium ion (K+) is the principal intracellular cation of most body tissues. Potassium ions participate in a number of essential physiological processes, including the maintenance of intracellular tonicity; the transmission of nerve impulses; the contraction of cardiac, skeletal, and smooth muscle; and the maintenance of normal renal function. The intracellular concentration of potassium is approximately 150 to 160 mEq per liter.

The normal adult plasma concentration is 3.5 to 5 mEq per liter. An active ion transport system maintains this gradient across the plasma membrane. Potassium is a normal dietary constituent and under steady-state conditions the amount of potassium absorbed from the gastrointestinal tract is equal to the amount excreted in the urine.

The usual dietary intake of potassium is 50 to 100 mEq per day.

12.3Pharmacokinetics Each crystal of KCl is microencapsulated and allows for the controlled release of potassium and chloride ions over an eight- to ten-hour period. Specific Populations Cirrhotics Based on publish literature, the baseline corrected serum concentrations of potassium measured over 3 hours after administration in cirrhotic subjects who received an oral potassium load rose to approximately twice that of normal subjects who received the same load.
