Find answers to some commonly asked questions about Kerendia.

Will the 10-mg strength of Kerendia cause fewer side effects than the 20-mg strength?

It’s possible. Kerendia is available in two strengths: 10 milligrams (mg) and 20 mg. Lower doses may lower the risk of having a high level of potassium in the blood while taking Kerendia. But in general, Kerendia’s side effects are likely to be the same regardless of the strength you take.

While you’re taking Kerendia, your doctor will check your potassium level with a blood test. They’ll likely do this every 4 weeks.

If you have a high potassium level during treatment, your doctor may temporarily stop your Kerendia treatment until your level returns to a normal range.

Once your potassium level is within a normal range, your doctor may restart your Kerendia treatment at a lower dosage. Doing so could help lower the risk of having a high potassium level again.

Do other similar drugs, such as Farxiga, have the same use as Kerendia?

Kerendia is used to help reduce certain risks from chronic kidney disease in people with type 2 diabetes.

Another group of drugs with a similar use to Kerendia is called sodium-glucose transport protein 2 inhibitors. This group includes medications such as dapagliflozin (Farxiga) and empagliflozin (Jardiance). These drugs can lower certain risks related to type 2 diabetes. These include risks related to kidney disease and cardiovascular (heart and blood vessel) disease.

One of the risks Kerendia helps reduce is the risk of hospitalization for heart failure. A group of drugs called steroidal mineralocorticoid receptor antagonists (MRAs) can also be used to lower this risk. Examples of steroidal MRAs include spironolactone (Aldactone, Carospir) and eplerenone (Inspra).

To learn more about how Kerendia compares with similar drugs, talk with your doctor. They can help find the right treatment for your condition.

What is the cost of Kerendia with Medicare?

The cost of Kerendia with Medicare depends on your specific Medicare plan. Factors that may influence your cost include your deductible and copay. (Your deductible is the amount you’ll pay each year before Medicare fully covers the cost of your medications. Your copay is the set amount you’ll pay for prescriptions.)

To find out the cost of Kerendia with your specific Medicare plan, talk with your Medicare provider. For other details about the cost of Kerendia, see this article.

Is Kerendia a diuretic?

No, Kerendia is not a diuretic. Diuretics are medications that help your body get rid of excess sodium (salt) and water. They’re often used to treat conditions such as high blood pressure and heart failure.

Even though Kerendia isn’t a diuretic, it has some effects that are similar to certain diuretics. For example, Kerendia can lower sodium and water levels in the body.

Questions about Kerendia’s dosing

Below are some common questions about Kerendia’s dosing.

What if I miss a dose of Kerendia? What you’ll do about a missed dose of Kerendia depends on when you realize that you’ve missed a dose.

If you remember on the same day as your missed dose, you can take the dose as soon as you remember. But if you remember on a different day than your missed dose (such as the next day), you should skip the missed dose. Then take your next dose at its usual time.

Kerendia is used to help reduce specific risks from chronic kidney disease (CKD) in adults with type 2 diabetes. These risks include:

How does Kerendia work?

With type 2 diabetes, high blood sugar levels over a long period of time can cause damage to your blood vessels, heart, and kidneys. Type 2 diabetes can also cause certain proteins in these organs to become overactive, which can lead to further damage.

Kerendia works by blocking these overactive proteins in your body. This helps slow kidney damage that may happen with type 2 diabetes and CKD.

If you have more questions about how Kerendia works, talk with your doctor or pharmacist.

About CKD

With CKD, your kidneys gradually stop working as they should. This leads to a buildup of waste in your blood that can lead to other health problems. Examples of these problems include high blood pressure and heart disease. Over time, CKD can lead to worsening kidney function that may lead to kidney failure.

Your doctor will explain how you should take Kerendia. They’ll also explain how much to take and how often. Be sure to follow your doctor’s instructions.

Taking Kerendia

Kerendia comes as a tablet that you swallow.

Accessible medication containers and labels

If it’s hard for you to read the label on your prescription, tell your doctor or pharmacist. Certain pharmacies may provide medication labels that:

  • have large print
  • use braille
  • contain a code you can scan with a smartphone to change the text into audio

Your doctor or pharmacist may be able to recommend a pharmacy that offers these options if your current pharmacy doesn’t.

Also, if you’re having trouble opening your medication bottles, let your pharmacist know. They may be able to put Kerendia in an easy-open container. Your pharmacist may also recommend tools to help make it simpler to open the drug’s container.

Questions about taking Kerendia

Below are some common questions about taking Kerendia.

Warnings

Kerendia can sometimes cause harmful effects in people who have certain conditions. This is known as a drug-condition interaction. Other factors may also affect whether Kerendia is a good treatment option for you.

Talk with your doctor about your health history before you take Kerendia. Factors to consider include those described below.

High level of potassium in the blood. Kerendia may cause a high level of potassium in the blood. If your potassium level is already high before treatment, the drug could worsen your condition.

Before starting Kerendia treatment, your doctor may check your potassium level with a blood test. They’ll tell you whether your potassium level is within a range that makes it safe to start treatment with Kerendia.

Adrenal insufficiency. Doctors usually will not prescribe Kerendia for people with adrenal insufficiency. This condition may cause a high level of potassium in your blood. Kerendia can also cause high potassium levels.

You may have a higher risk of low potassium levels if you have adrenal insufficiency and take Kerendia. Your doctor can recommend a safer treatment option for your condition.

Allergic reaction. If you’ve had an allergic reaction to Kerendia or any of its ingredients, your doctor will likely not prescribe Kerendia. Ask them what other medications are better options for you.

Kerendia and alcohol

Kerendia isn’t known to interact with alcohol. But it’s important to note that alcohol can affect your blood sugar levels. Kerendia is used in people who have type 2 diabetes. Drinking alcohol could make it hard to manage your blood sugar while taking this drug.

If you drink alcohol, talk with your doctor about how much (if any) is safe for you to drink while taking Kerendia.

Pregnancy and breastfeeding

It’s not known whether Kerendia is safe to take while pregnant or breastfeeding. If you have questions about taking this drug during pregnancy or while breastfeeding, talk with your doctor.

Do not take more Kerendia than your doctor prescribes. Using more than this can lead to serious side effects.
