Drug Information:
Kionex binds itself to Potassium in your digestive tract. This helps prevent your body from absorbing too much Potassium. Kionex is used to treat high levels of Potassium in the blood, also called hyperkalemia. Kionex works differently from other medicines because it passes into your intestines without being absorbed into your blood stream. Kionex may also be used for purposes not listed in this medication guide. You should not use Kionex if you have low Potassium levels or a bowel obstruction. Learn more
