Potassium chloride products have been approved by the U.S. Food and Drug Administration (FDA) for the treatment and prevention of potassium deficiency in various conditions, such as hypokalemia (low potassium levels) and as a supplement in certain medical situations.
Mechanism of action
Potassium chloride (KCL) is an electrolyte supplement that plays a crucial role in maintaining proper functioning of cells, nerves, and muscles. It helps regulate fluid balance, nerve transmission, and muscle contraction. Supplementing with potassium chloride helps replenish potassium levels in the body.
Uses of potassium chloride
Potassium chloride is primarily used to prevent or treat potassium deficiency, particularly in conditions that lead to low potassium levels, such as certain kidney disorders, prolonged vomiting or diarrhea, and the use of certain medications. It may be used as a supplement during periods of increased potassium loss, such as during intense physical activity or heat exposure.
Low potassium levels may increase calcium in the body. The combined effect can cause heart ventricle arrhythmia or an irregular heartbeat in some people.
Dosage of potassium chloride
The dosage of potassium chloride varies depending on the individual’s potassium levels, the specific condition being treated, and the product formulation. It is important to follow the dosage instructions provided by your healthcare provider or the directions on the product packaging.
The tablets should be taken with a full glass of water or as directed. You may break the tablets into two, if you have trouble swallowing them. If you forget to take a dose, take it as soon as you can. If it is almost time for your next dose, skip the missed dose and take your next dose at the usual time.
Forms available of potassium chloride
Potassium chloride is available in various forms, including extended-release tablets, immediate-release tablets, and effervescent tablets. It is also available in oral solution and powder for reconstitution. Store potassium chloride tablets at room temperature away from moisture and heat.
