Potassium supplement to treat or prevent hypokalemia; potassium is the major intracellular cation essential for nerve transmission, muscle contraction, and acid-base balance.
Calcium ion is essential for normal cell function, including muscle contraction, nerve transmission, and blood coagulation. It acts as a positive inotrope by increasing myocardial contractility and also corrects hypocalcemia.
Treatment of hypokalemia,Prevention of hypokalemia in patients receiving diuretics or other drugs that deplete potassium
Cardiac resuscitation (e.g., asystole, pulseless electrical activity) due to hyperkalemia, hypocalcemia, or calcium channel blocker overdose,Severe hypocalcemia,Treatment of hypermagnesemia,Treatment of calcium channel blocker overdose,Cardiopulmonary bypass,Intraoperative floppy iris syndrome (off-label)
Oral: 20 m Eq (2 tablets) 2-4 times daily with meals; maximum 100 m Eq/day.
IV: 500 mg to 1 g (5-10 m L of 10% solution) administered slowly at a rate not exceeding 0.5-1 m L/min. May be repeated as needed based on serum calcium levels and clinical response.
Terminal elimination half-life is approximately 3-5 hours in healthy adults, reflecting rapid equilibration with the total body potassium pool. Clinically, the half-life is not directly applicable due to extensive intracellular distribution; steady-state is achieved within 24-48 hours.
2-4 hours in patients with normal renal function; prolonged in renal impairment.
Potassium is primarily excreted unchanged by the kidneys; metabolism is not significant.
Calcium chloride dissociates to release calcium ions which are primarily regulated by the kidney; no significant hepatic metabolism.
Primarily renal elimination (>90% as unchanged drug); minor biliary/fecal excretion (<5%). Excretion is via glomerular filtration and tubular reabsorption; potassium excretion is influenced by aldosterone and acid-base status.
Primarily renal (80-90% as ionized calcium); minor fecal elimination (<10%).
Potassium is not significantly protein-bound; <5% bound to plasma proteins.
Approximately 45-50% bound primarily to albumin.
Approximately 0.5 L/kg, representing distribution primarily into intracellular fluid (98% of total body potassium is intracellular). Clinical meaning: Low Vd indicates limited distribution to extracellular space; high intracellular uptake requires careful dosing to avoid hyperkalemia.
0.5-0.6 L/kg; primarily distributed in extracellular fluid.
Oral: >90% absorbed via passive diffusion along the gastrointestinal tract. Intravenous: 100% bioavailability.
Not applicable; administered only intravenously. Oral calcium salts have variable bioavailability (25-40%).
GFR 30-50 m L/min: reduce dose by 25%; GFR 10-29 m L/min: reduce dose by 50%; GFR <10 m L/min: avoid use.
GFR 30-60 m L/min: Use with caution; monitor serum calcium and phosphate levels. GFR <30 m L/min: Avoid use or use only if benefit outweighs risk; reduce dose by 50% and monitor serum calcium and phosphate closely.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 25%; Child-Pugh C: avoid use.
No dose adjustment recommended for Child-Pugh Class A or B. Child-Pugh Class C: Use with caution; monitor serum calcium and cardiac function due to potential for accumulation of calcium and effects on myocardial contractility.
Oral: 1-3 m Eq/kg/day in divided doses, maximum 3 m Eq/kg/day; not recommended for children <1 year.
IV: 0.2 m L/kg (20 mg/kg) of 10% solution, administered slowly at a rate not exceeding 0.5-1 m L/min. Dose may be repeated if needed. Maximum single dose: 1 g (10 m L).
Start at lowest dose (10 m Eq twice daily); monitor renal function and potassium levels; avoid doses exceeding 40 m Eq/day.
No specific dose adjustment, but consider reduced renal function common in elderly; use lowest effective dose and monitor serum calcium, phosphate, and cardiac status. Infusion rate should be slow (0.5-1 m L/min) to avoid adverse effects.
Warning: Potassium chloride can cause hyperkalemia and cardiac arrest if given too rapidly or in excessive doses. Avoid in patients with severe renal impairment, adrenal insufficiency, or concurrent use of potassium-sparing diuretics.
Do not administer by intracardiac injection due to risk of myocardial rupture and cardiac arrest.
Monitor serum potassium levels and renal function; avoid high doses or rapid infusion; use with caution in patients with cardiac disease or receiving digitalis; gastrointestinal irritation may occur with oral preparations.
Extravasation can cause tissue necrosis; administer slowly to avoid hypercalcemia; use with caution in digitalis toxicity as hypercalcemia potentiates digoxin toxicity; monitor serum calcium levels; avoid in patients with renal failure unless severe hypocalcemia exists.
Severe renal impairment (e.g., anuria, oliguria), untreated Addison's disease, hyperkalemia from any cause, acute dehydration, heat cramps, concurrent use of potassium-sparing diuretics (e.g., amiloride, spironolactone), hypersensitivity to potassium chloride.
Hypercalcemia, ventricular fibrillation during cardiac arrest, concurrent digitalis therapy (relative), patients with known hypersensitivity to calcium salts.
Avoid salt substitutes and low-sodium products that contain potassium chloride. No specific food restrictions beyond ensuring adequate water intake with each dose to prevent esophageal or gastric irritation.
Avoid calcium-fortified foods and dairy products if serum calcium is elevated. High doses of vitamin D can increase calcium absorption, leading to hypercalcemia. Caffeine and alcohol may increase urinary calcium excretion, potentially reducing efficacy. Oxalate-rich foods (spinach, rhubarb) and phytate-rich foods (whole grains) bind calcium and may reduce absorption, but this is less relevant with IV administration.
Potassium chloride (the active ingredient in Kaon CL-10) is not associated with teratogenic risk in any trimester. No fetal malformations or developmental toxicity have been reported. Hypokalemia itself may pose maternal and fetal risks, but the drug does not have intrinsic teratogenic potential.
No evidence of teratogenicity in animal studies; calcium chloride is a normal blood constituent. First trimester: no known risk. Second and third trimesters: use only if clearly needed; high doses may cause hypercalcemia in fetus (e.g., hypotonia, poor feeding). Intravenous administration near term may suppress fetal parathyroid function.
Potassium chloride is a normal constituent of breast milk. M/P ratio not applicable as potassium is present endogenously. Supplementation to correct maternal hypokalemia is considered safe during breastfeeding, as potassium levels in milk are tightly regulated and maternal supplementation does not significantly alter infant potassium levels.
Calcium is excreted in breast milk but in normal physiological amounts. M/P ratio not established; supplemental calcium likely safe but high IV doses may increase milk calcium concentration. Monitor infant for hypercalcemia with prolonged high-dose maternal therapy.
No dose adjustment required for pregnancy. Maternal potassium requirements may increase slightly due to increased plasma volume and renal blood flow, but hypokalemia should be corrected per standard guidelines. Monitor serum potassium to avoid hyperkalemia.
No specific dose adjustment required; pharmacokinetic changes in pregnancy (e.g., increased plasma volume) may necessitate higher doses to achieve desired serum calcium levels, but titrate to effect and serum calcium monitoring. Avoid bolus administration during labor; use slow IV infusion.
Kaon CL-10 is a solid oral dosage form of potassium chloride (KCl) 10 m Eq. Do not split or crush tablets; they must be swallowed whole with a full glass of water to reduce GI irritation. Monitor serum potassium, renal function, and ECG. Use with caution in patients with impaired renal function or those on ACE inhibitors, ARBs, or potassium-sparing diuretics. Rapid IV correction is reserved for severe hypokalemia with ECG changes.
Calcium chloride provides approximately 3 times more elemental calcium per m L than calcium gluconate. Due to its high osmolality (approx. 2000 m Osm/L), it is a severe vesicant; central line administration is strongly preferred to prevent tissue necrosis if extravasation occurs. For peripheral IV, use a large bore vein with good blood flow and avoid hand/wrist veins. In cardiac arrest (e.g., hyperkalemia, calcium channel blocker overdose), give 10 m L of 10% solution (1 g) IV push; may repeat every 10 minutes if needed. Monitor serum calcium, magnesium, and phosphate levels; correct hypomagnesemia before calcium therapy to prevent refractory hypocalcemia. Contraindicated in digitalis toxicity (can precipitate fatal arrhythmias). Not for IM or SC use.

No interactions on record
"Calcium chloride, an intravenous calcium salt, directly increases serum ionized calcium levels, which can antagonize the pharmacodynamic effects of the calcium channel blocker manidipine. Manidipine inhibits L-type calcium channels in vascular smooth muscle, leading to vasodilation and reduced blood pressure. Elevated extracellular calcium from calcium chloride administration can overcome this blockade, potentially diminishing the antihypertensive efficacy of manidipine and increasing the risk of hypertensive urgency or elevated blood pressure."
"Calcium chloride, a source of calcium ions, can chelate with bisphosphonates such as risedronic acid in the gastrointestinal tract, forming insoluble complexes that reduce the oral absorption of risedronic acid. This interaction may lead to decreased serum concentrations of risedronic acid, potentially compromising its therapeutic efficacy in preventing bone resorption. Patients may experience reduced bone mineral density or increased risk of fractures if the interaction is significant."
"Calcium chloride, a source of calcium ions, can chelate alendronic acid (a bisphosphonate) in the gastrointestinal tract, forming insoluble complexes that reduce the absorption of alendronic acid. This interaction can significantly decrease the systemic bioavailability and serum concentration of alendronic acid, potentially compromising its therapeutic efficacy in preventing bone resorption and treating osteoporosis. Clinically, patients may experience reduced bone mineral density improvement or increased fracture risk if the drugs are co-administered."
