What is Kionex?
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.
Warnings
You should not use Kionex if you have low potassium levels or a bowel obstruction.
Do not give this medicine orally (by mouth) to a newborn baby.
Avoid taking other medicines by mouth within 3 hours before or 3 hours after you take Kionex (or 6 hours before/after if you have slow digestion).
Before taking this medicine
You should not use Kionex if you are allergic to it, or if you have:

a bowel obstruction.
Tell your doctor if you have ever had:
heart disease or high blood pressure;
a weak immune system caused using certain medicine;

an electrolyte imbalance (such as low levels of potassium, calcium, or magnesium in your blood);
severe burns;
a bowel disorder, or surgery on your intestines;
if you are dehydrated; or
