Uses, Dosage, Side Effects, Composition, And More.


The main cation in the intracellular fluid is potassium chloride. It actively participates in the contraction of cardiac skeletal and smooth muscles, the conduction of nerve impulses in the heart, brain, and skeletal muscle, the maintenance of normal renal function, acid-base balance, glucose metabolism, and gastric secretion.

Rarely, metabolic acidosis and hyperchloremia may coexist with potassium depletion in patients with renal tubular acidosis, for example. Using potassium salts other than potassium chloride in these patients, such as potassium bicarbonate, potassium citrate, potassium acetate, or potassium gluconate, is the best way to replace potassium.

Uses Of KCL-Retard Slow K Tablet

It is used to treat

  1. Drug-induced hypokalemia
  2. Liver cirrhosis
  3. Nausea
  4. Vomitin
  5. Cholera
  6. Diarrhoea
  7. Muscular weakness
  8. Paralysis
  9. Diabetic ketoacidosis

KCL-retard Slow-K is also used as part of the treatment for the following conditions: Dehydration, Dry Mouth, Hypokalemia, Hypotonic Dehydration, Hypovolaemia, Isotonic Dehydration, Significantly Reduced Food Intake, Metabolic Acidosis, Hypodermolysis, Mild, Moderate Metabolic Acidosis, Ocular edema, Acid-Base Balance, Bowel Preparation Therapy, Electrolyte

How It Works

Normal potassium levels could be able to be restored with more potassium in the form of high potassium foods or potassium chloride.


KCL-retard Slow-K dosage

Oral: Dosage must be adjusted to the individual needs of each patient.

Adults: In severe deficiencies 3-6 tablets or 4-8 teaspoonful or 25-50 mmol per day orally in divided doses for some days with fruit juice, sweet or plain water.

Children: ½-1 teaspoonful twice daily or 1-3 mmol/kg body weight a day in several divided doses. Patient should take Potassium chloride with meals.

Intravenous: Severe acute hypokalaemia:

Adult: 75 mg is best prescribed.


It is important to recognize that hyperkalemia is usually asymptomatic and may be manifested only by an increased serum potassium concentration and characteristic electrocardiographic changes (peaking of T-waves, loss of P-wave, depression of S-T segment, and prolongation of the QT interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest.

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 intravenously, potentially fatal hyperkalemia can result.


  1. Do not take it in cases of :
  2. Cardiovascular disease
  3. Acute dehydration
  4. Substantial tissue damage or renal or adrenocortical insufficiency. 
  5. Pregnancy.

 If severe nausea, vomiting, or abdominal discomfort appears, stop the medication. In renal dysfunction, potassium may accumulate.

Can I continuously take KCL-retard Slow-K?

Never take more of it or take it more frequently than directed. Per dose, do not exceed 20 milliequivalents.

Is it okay to take a daily dose of KCL-retard Slow-K supplements?

If your doctor has prescribed KCL-retard Slow-K pills, you may take them every day.

When should KCL-retard Slow-K be stopped being taken?

If you experience any of the following symptoms as a result of a high potassium level: nausea, weakness, tingling, chest pain, irregular heartbeats, loss of movement, severe throat irritation, stomach bloating, severe vomiting, or severe stomach pain, stop using this KCL-retard Slow-K and contact your doctor right away.

Can I stop taking Slow-K with KCL?

Without consulting your doctor, do not discontinue using KCL-retard Slow-K since this could make your situation worse.

Those who shouldn’t use KCL-retard Slow-K

If you have hyperkalemia, or if you also take a diuretic that is “potassium-sparing,” you should avoid using KCL-retard Slow-K. If you are allergic to potassium chloride, have hyperkalemia (high blood potassium levels), or take a “potassium-sparing” diuretic (water pill) such as amiloride, spironolactone, or triamterene, you should avoid using potassium chloride.

What occurs if I don’t take a dose?

The missed dose should be taken as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose. To make up for a missed dose, do not take more medication.

If I take too much, what happens?

Obtain immediate medical help. Muscle weakness, chest pain, and irregular heartbeats are all possible overdose signs.

Can KCL-retard Slow-K lead to cardiovascular issues?

The dangers of receiving potassium chloride intravenously are well documented. It can quickly lead to cardiac arrest if injected too quickly or in a large dose. Virtually any arrhythmia may be seen as a result of the complicated effects of hyperkalemia on the heart.

Can Slow-K which is KCL-retardant harm my kidneys?

The body needs KCL-retard Slow-K, an electrolyte, and mineral, to sustain important bodily functions. It is one of the seven important macrominerals and helps the kidneys work properly. Kidney problems can arise from either too much or too little potassium in the body.

Can liver issues be brought on by KCL-retard Slow-K?

Low serum KCL-retarded Non-alcoholic fatty liver disease and its accompanying metabolic diseases are linked to slow-K levels.

Is KCL-retard Slow-K good for high blood pressure?

According to clinical and epidemiological studies, consuming KCL-retard Slow-K decreases blood pressure.
