Potassium is essential for the healthy functioning of our body. Potassium is needed for the functioning of the heart, the nervous system, and the muscles. But like anything, too much of it can be dangerous. Especially for someone with certain kidney problems, there is a risk of high potassium levels in the body. So, has your doctor prescribed you a medicine to control your potassium levels? Today we are talking about one such medicine, `Sodium Zirconium Cyclosilicate`.

This medicine is a medicine that helps reduce high potassium levels in your body. It is commonly found in our market under the brand name `Lokelma`.
