In an emergency situation, it may not be possible before you are treated with sodium polystyrene sulfonate to tell your caregivers about any health conditions you have or if you are pregnant or breast-feeding. However, make sure any doctor caring for your pregnancy or your baby knows that you have received this medication.

Tell your caregivers right away if you have any signs that your potassium level is getting too low, such as: pain or fluttering in your chest, uneven heartbeats, feeling irritable or confused, severe muscle weakness, breathing problems, or inability to move your muscles.

Tell your doctor if you also take digoxin (digitalis, Lanoxin), lithium (Eskalith, Lithobid), thyroxine, or a diuretic (water pill).

Do not use salt substitutes or take potassium or calcium supplements unless your doctor has told you to. Avoid using antacids or laxatives without your doctor's advice.

You will need to keep using this medication even if you feel fine. Hyperkalemia often has no symptoms that you will notice.

The powder form of this medicine is mixed with water, or syrup (to make it taste better if given by mouth).

If you are given the rectal enema, the liquid will be given slowly while you are lying down. You may need to hold the enema in for up to several hours. The sodium polystyrene sulfonate enema is usually followed with a second cleansing enema.

You will need to keep using this medication even if you feel fine. Hyperkalemia often has no symptoms that you will notice.
