Kayexalate (Sodium polystyrene sulfonate) (Sodium polystyrene sulfonate) — Uses, Dosage, Side Effects & Safety

Drug class: Urogenital & Renal System

Overview

Kayexalate (sodium polystyrene sulfonate) is a medication used to treat high levels of potassium in the blood, a condition known as hyperkalemia. High potassium can be dangerous and may lead to heart rhythm problems if not managed promptly. This medicine works by binding to potassium in your intestines, allowing your body to remove it through the stool. It does not work immediately and is not suitable for emergency treatment of life-threatening hyperkalemia. Key points for patients: Always take Kayexalate exactly as prescribed. Do not use it for mild or temporary increases in potassium unless directed by your doctor. Inform your healthcare provider about all other medications and supplements you are taking, as Kayexalate can interact with many drugs.
