Kayexalate: An Essential Medication for the Management of Hyperkalemia Hyperkalemia is a condition characterized by an abnormally high concentration of potassium in the blood, which can lead to serious health complications such as cardiac arrest, muscle weakness, and paralysis. Potassium is vital for the proper function of many body systems, including nerve and muscle function. Kayexalate is a medication that is commonly used for the treatment of hyperkalemia. This article will cover the uses, dosage, demographics, side effects, interactions, and generic options of Kayexalate. Uses of Kayexalate Kayexalate is a resin that works by exchanging sodium ions for potassium ions in the colon. This leads to the excretion of potassium through the stool, effectively lowering the potassium levels in the blood. Kayexalate is used to treat hyperkalemia, which can be caused by many factors, including kidney disease, medication side effects, and dehydration. Kayexalate is also used as a bowel cleanser before surgery or radiological procedures. Dosage of Kayexalate The dosage of Kayexalate varies depending on the patient's age, weight, and medical conditions. The medication comes in the form of a powder that is mixed with water before administration. The usual dose for adults is 15-60 grams daily, divided into three to four doses.
