Why is this medication prescribed?
Kayexalate is a brand name for a medication called sodium polystyrene sulfonate. It is prescribed for the treatment of hyperkalemia, which is a condition characterized by high levels of potassium in the blood.
Hyperkalemia can occur due to various reasons, such as kidney disease, certain medications, or other medical conditions. Elevated potassium levels can be dangerous and disrupt the normal functioning of the heart and other organs.
Kayexalate works by binding to potassium in the gastrointestinal tract, preventing its absorption into the bloodstream. The medication exchanges sodium ions for potassium ions, resulting in the elimination of excess potassium through the stool.
By lowering blood potassium levels, Kayexalate helps restore the balance of electrolytes in the body and reduce the risk of complications associated with hyperkalemia. It is typically prescribed in conjunction with other treatments, such as dietary changes and adjustments to medications that may contribute to high potassium levels.
How should this medicine be used?
Kayexalate is usually administered orally or rectally, depending on the individual’s condition and the severity of hyperkalemia. Here are the general guidelines for using Kayexalate:
- Oral Administration:
- The medication is available as a powder or suspension and should be mixed with water or syrup before taking.
- Follow the instructions provided by your healthcare provider or the medication label regarding the dosage and preparation.
- Shake the suspension well before use if you are using the liquid form.
- Take Kayexalate by mouth as directed by your doctor.
- It is important to take Kayexalate with sufficient amounts of water to ensure proper hydration.
- Rectal Administration:
- If the patient cannot take the medication orally or is unable to swallow, rectal administration may be considered.
- Kayexalate can be given as a retention enema.
- Follow the instructions given by your healthcare provider on how to administer the enema properly.
- Retain the enema for the prescribed duration as instructed by your doctor before evacuating the bowel.
It is crucial to follow your healthcare provider’s specific instructions regarding the dosage, frequency, and duration of Kayexalate treatment. Your doctor will determine the appropriate dose based on your potassium levels and overall health condition.
Remember to inform your doctor about any other medications you are taking, as Kayexalate may interact with certain drugs. Also, it is essential to stay well-hydrated during Kayexalate treatment to maintain fluid balance.

What side effects can this medication cause?
Kayexalate (sodium polystyrene sulfonate) may cause certain side effects. It’s important to note that not everyone experiences these side effects, and some individuals may not experience any at all. However, here are some possible side effects associated with Kayexalate:
- Gastrointestinal effects: The most common side effects of Kayexalate are related to the gastrointestinal system. These can include nausea, vomiting, stomach pain, loss of appetite, constipation, and diarrhea. In some cases, the medication may cause more serious gastrointestinal problems, such as bowel obstruction or perforation. If you experience severe abdominal pain, rectal bleeding, or any concerning gastrointestinal symptoms, seek medical attention immediately.
- Electrolyte imbalances: Kayexalate works by exchanging sodium ions for potassium ions in the intestines. As a result, it can cause electrolyte imbalances, particularly low levels of sodium or calcium in the blood. These imbalances can lead to symptoms such as muscle cramps, weakness, fatigue, irregular heartbeat, or changes in mental status. Your healthcare provider will monitor your electrolyte levels during treatment to prevent complications.
- Allergic reactions: In rare cases, allergic reactions to Kayexalate may occur. Symptoms of an allergic reaction can include rash, itching, swelling, severe dizziness, difficulty breathing, or tightness in the chest. If you experience any signs of an allergic reaction, seek immediate medical attention.
- Intestinal necrosis: Although very rare, there have been reports of intestinal necrosis (tissue death) associated with the use of Kayexalate. This serious complication can cause severe abdominal pain, bloody stools, or other signs of intestinal damage. If you experience these symptoms, seek medical help right away.
It’s important to promptly report any unusual or severe side effects to your healthcare provider. They can evaluate your symptoms and determine the appropriate course of action. Additionally, always follow your healthcare provider’s instructions and dosing recommendations to minimize the risk of side effects.
