Actual product appearance may differ slightly.
Why is this medication prescribed?
Sodium polystyrene sulfonate is a medication that is primarily prescribed for the treatment of high levels of potassium in the blood, a condition known as hyperkalemia. It is commonly used in individuals with kidney disease or those taking medications that can increase potassium levels, such as certain blood pressure medications or potassium supplements.
Hyperkalemia can be a serious medical condition that can lead to abnormal heart rhythms and other complications. Sodium polystyrene sulfonate works by binding to potassium in the gastrointestinal tract, preventing its absorption and promoting its elimination through the feces. By reducing potassium levels in the blood, this medication helps restore normal potassium balance and prevent potential health risks associated with hyperkalemia.
How should this medicine be used?
Sodium polystyrene sulfonate is typically administered orally or rectally, depending on the formulation prescribed by the healthcare professional. Here are the general guidelines for its use:
- Oral Administration: If the medication is prescribed in oral form (powder or suspension), it is usually mixed with a small amount of water or a sweetened liquid. Follow the specific instructions provided by your healthcare provider or the product label. It is important to shake the suspension well before use. Drink the mixture immediately after preparation.
- Rectal Administration: If the medication is prescribed in rectal form (enema), it is typically administered using an enema applicator. Follow the specific instructions provided by your healthcare provider or the product label. Retain the enema in the rectum for the recommended period before expelling it.
It is important to adhere to the prescribed dosage and administration schedule. Do not take more than the recommended dose or use it more frequently than instructed by your healthcare professional. If you have any doubts or questions regarding the proper use of sodium polystyrene sulfonate, consult your doctor or pharmacist for clarification.
Remember to inform your healthcare provider about any other medications you are taking, as sodium polystyrene sulfonate may interact with certain drugs, potentially affecting their effectiveness or causing adverse effects.
