CompositionPolystern Sachet 15gm is a medicine used to manage high levels of potassium in the blood (hyperkalaemia). It is particularly useful for people with chronic kidney disease, those on dialysis, and those with acute kidney failure, where the body cannot remove potassium properly.
It belongs to a group of medicines called ion exchange resins. It works in the gut by binding to excess potassium so that it is removed from the body, which helps bring potassium levels back to normal and ease symptoms such as muscle weakness and an irregular heartbeat. The powder is mixed with water or another suitable liquid and taken by mouth as directed by your doctor.
Some general measures help alongside this medicine. These include following any advice on a low-potassium diet and attending the regular blood tests your doctor arranges to check your potassium levels.
Before taking this medicine, tell your doctor about any bowel problems, calcium problems, or other medicines you take. Tell your doctor about constipation, muscle weakness, or confusion, as your potassium and other blood salts may need checking. Take it at a different time from other medicines, as it can affect how they are absorbed.
