Kayexalate

1 What is Kayexalate?

Brand: Kayexalate, Kionex.

Generic: Sodium Polystyrene Sulfonate

Kayexalate is used to treat abnormally high levels of potassium in the body.

Potassium is an important micronutrient and electrolyte in cells. Potassium levels can become abnormally high due to kidney disease, problems in the adrenal glands, having type-1 diabetes, sustaining burns or other severe injuries, a side effect of medicines like heart medications and alcoholism.

High potassium levels are called hyperkalemia, and it can result in abnormal heart rate rhythms, muscle weakness, and paralysis. In most disease processes, hyperkalemia is a serious and potentially life-threatening disorder.

Sodium Polystyrene Sulfonate works in the intestines. As it passes through the intestines, it causes the release of potassium from the bloodstream into the intestines, causing potassium levels in the body to go down.

Sodium Polystyrene Sulfonate is a prescription medication.

Rarely, Sodium Polystyrene Sulfonate can cause intestinal necrosis or death of tissues in the intestines. Patients using Sodium Polystyrene Sulfonate require close monitoring of potassium and other electrolytes such as magnesium and calcium.

Only use Sodium Polystyrene Sulfonate in accordance with doctor’s instructions.
