Frequently asked questions

It’s important to learn about all the medications you take. Here are some answers to frequently asked questions about KERENDIA. Remember, your doctor is always the best source to discuss any questions you may have about your treatment and whether KERENDIA is right for you.

    KERENDIA is a prescription medicine used to treat adults with chronic kidney disease associated with type 2 diabetes to reduce the risk of:

    • Worsening of kidney disease
    • End-stage kidney disease (ESKD)
    • Death due to cardiovascular disease
    • Heart attack
    • Hospitalization for heart failure  

    First, talk to your doctor about KERENDIA. If you and your doctor decide that KERENDIA is right for you, you will be prescribed KERENDIA for the treatment of your chronic kidney disease associated with type 2 diabetes.

    Before starting you on KERENDIA, your doctor will check the potassium levels in your blood and do an eGFR test to check your level of kidney function.

    After starting your treatment with KERENDIA, your doctor will work with you to schedule your lab work, including your potassium level, and adjust or withhold your dose, as needed.


    Take KERENDIA exactly as your healthcare provider tells you. Check with your doctor or pharmacist if you are not sure.

    Your healthcare provider may change your dose if needed.

    Take your prescribed dose of KERENDIA once daily with or without food. Avoid eating grapefruit or drinking grapefruit juice during treatment with KERENDIA, as it may increase KERENDIA levels in the blood.

    Swallow KERENDIA tablets whole. If you are unable to swallow the whole tablet, you can crush the tablet and mix it with water or soft foods.

    If you miss a dose of KERENDIA, take your prescribed dose as soon as you remember before the next scheduled dose. Do not take 2 doses on the same day to make up for a missed dose.

    Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, salt substitutes, vitamins, and herbal or potassium supplements. KERENDIA may affect the way other medicines work, and other medicines may affect how KERENDIA works. Take KERENDIA as prescribed and do not start or stop any medicine before talking with your doctor, including your diabetes and high blood pressure medications.

    Store KERENDIA at room temperature between 68°F to 77°F (20°C to 25°C).
