Precautions
It is very important that your doctor check you or your child closely to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.
Hypokalemia (low potassium in the blood) may occur while you are using this medicine. Check with your doctor right away if you have the following symptoms: confusion, dry mouth, increased thirst, irregular heartbeat, irritability, muscle cramps, nausea or vomiting, or shortness of breath.
If you are taking aluminum or magnesium-containing antacids or laxatives, talk to your doctor first before using them together with sodium polystyrene sulfonate. These medicines may keep sodium polystyrene sulfonate from working properly and may cause serious side effects.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
