What is potassium chloride, and how does it work (mechanism of action)?
Potassium preparations are used for supplementing potassium in order to treat or prevent low potassium levels in the blood (hypokalemia). Potassium is a major mineral (electrolyte) that is important for the function of every cell in the body. For example, it is important in nerve conduction, muscle contraction, and kidney function. Normal daily dietary intake of potassium is 40-150 mEq. Potassium deficiency occurs when potassium loss exceeds intake. Potassium depletion may be caused by excessive vomiting or diarrhea, diabetic ketoacidosis, diuretics (for example, furosemide [Lasix]), starvation, and rare disorders of the adrenal glands. Potassium deficiency causes weakness, fatigue, heart rhythm problems, paralysis, and kidney dysfunction.
What brand names are available for potassium chloride?

What are the side effects of potassium chloride?
Common reactions to potassium are primarily gastrointestinal and include reactions such as:
More important side effects include high blood potassium levels (hyperkalemia), abnormal heart beats, bleeding or perforation of the stomach or small intestine from ulcers, and narrowing (stricture) of the small intestine from healed ulcers. Irritation and damage to the stomach can be reduced by taking potassium supplements with meals or reducing the dose.
What is the dosage for potassium chloride?
The usual recommendation for treatment of hypokalemia in adults is 20-40 mEq 2 to 4 times daily. The dose for prevention is 20 mEq daily. Oral potassium is usually taken with meals and fluids to prevent intestinal problems.
Controlled release tablets should be swallowed whole.
Is potassium chloride safe to take if I'm pregnant or breastfeeding?
If the mother's blood potassium level is normal, use of potassium supplements should not adversely affect the infant.
