About Calcium Polystyrene Sulphonate
Calcium Polystyrene Sulphonate is a prescription medication used to treat high levels of potassium in your blood. This condition can affect how your heart beats if left untreated, making it very important to manage. This medicine helps your body safely remove excess potassium through your digestive tract.
Your doctor will determine how often you need to take Calcium Polystyrene Sulphonate based on your regular blood test results. It is typically taken consistently every day, and can be taken with or without food. To get the best results, your doctor will likely recommend dietary changes, such as eating fewer foods that are high in potassium.
