Kerendia (finerenone) is a  FDA approved tablet taken once a day by adults who have chronic kidney disease from type 2 diabetes.  Kerendia is used to slow down kidney damage, and also to reduce the risk of kidney failure, cardiovascular death, heart attack and being hospitalized for heart failure. Kerendia is from the class of meds called mineralocorticoid receptor antagonists.

Chronic kidney disease (CKD) is when your kidneys are not working properly and they work less effectively over time. Having type 2 diabetes increases your chances of having chronic kidney disease. Often type 2 diabetics do not have any symptoms in the early stages of CKD and they might not realize they have it until it is advanced and they may need to have dialysis or kidney transplant to survive. If you have diabetes it is important to get your kidneys checked regularly by having a blood and urine test, if you have signs of reduced kidney function or the start of CKD early treatment can help prevent you having extra health problems. 

When you have CKD you have health problems from fluid, electrolytes (minerals required for many bodily processes), and waste building up in the body. If you have CKD you are also at high risk of heart disease.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

You may take finerenone with or without food.

If you cannot swallow a tablet whole, crush the tablet and mix it with water or soft food such as applesauce. Swallow the mixture right away.

You will need medical tests.
