Calcium acetate is a medication used to help lower high phosphorus levels in patients with end-stage renal disease (ESRD). It works by binding to the phosphorus in the food you eat, which helps your body get rid of it through your stool. You typically take it in capsule form, starting with 2 capsules with each meal, and your doctor may increase this to 3 or 4 capsules as needed. It's important to know that you should not take this medication if you have high calcium levels in your blood. Additionally, be cautious if you are taking other medications that can also raise calcium levels, as this could lead to serious side effects.
