Finerenone should be taken once daily, typically in the morning, with or without food. To get the most benefit from the medication, it’s important to take it consistently at the same time each day. Here’s how you should use Finerenone:

1. Follow your doctor’s instructions: Always take Finerenone exactly as prescribed by your healthcare provider.
   
   
2. Do not skip doses: If you miss a dose, take it as soon as you remember unless it is close to the time for your next dose. Never take two doses at once to make up for a missed one.
   
   
3. Regular check-ups: During treatment with Finerenone, your healthcare provider may regularly check your kidney function and potassium levels to ensure the medication is working safely.
   
   

Stay hydrated: It’s important to maintain adequate hydration while on Finerenone. Make sure to drink plenty of water, unless your doctor advises otherwise.

Finerenone works by blocking the action of aldosterone, a hormone produced by the adrenal glands. Aldosterone plays a role in regulating blood pressure by promoting the retention of salt and water in the kidneys, which can increase fluid buildup in the body and raise blood pressure.

In patients with conditions like diabetic kidney disease or heart failure, aldosterone levels can become elevated, leading to fluid retention, inflammation, and fibrosis (scarring). These processes can worsen kidney function and contribute to heart failure symptoms.

By inhibiting the mineralocorticoid receptor, Finerenone:

• Reduces fluid retention: This helps prevent swelling and high blood pressure.
  
  
• Decreases inflammation: It helps prevent further damage to kidney tissues and heart tissues.
  
  
• Protects kidney function: In patients with diabetic kidney disease, Finerenone can slow the progression of kidney damage.
  
  

Improves heart function: In heart failure patients, it can help reduce the burden on the heart and improve symptoms.

As with any medication, Finerenone can cause side effects, although not everyone will experience them. Some common and more serious side effects include:

Common Side Effects:

• Elevated potassium levels (hyperkalemia): One of the most common side effects of Finerenone is an increase in blood potassium levels. High potassium levels can lead to heart rhythm problems, so regular monitoring of potassium levels is necessary.
  
  
• Low blood pressure (hypotension): Finerenone can cause a drop in blood pressure, especially when taken with other medications for high blood pressure or heart failure.
  
  
• Fatigue: Some people may experience tiredness or fatigue while on Finerenone.
  
  
• Dizziness: A feeling of lightheadedness or dizziness can occur, especially when standing up quickly.
  
  

Serious Side Effects:

• Severe hyperkalemia: Extremely high potassium levels can be dangerous and lead to heart arrhythmias or cardiac arrest. It’s important to monitor potassium levels regularly and seek immediate medical help if you experience symptoms such as muscle weakness, irregular heartbeats, or shortness of breath.
  
  
• Kidney problems: While Finerenone can protect the kidneys in some cases, it may cause worsening kidney function in others. Kidney function should be monitored during treatment.
  
  

If you experience any severe side effects or signs of an allergic reaction (e.g., swelling of the face, lips, tongue, or throat, difficulty breathing), seek medical attention immediately.

There are several important warnings and precautions to keep in mind when taking Finerenone:

• Kidney function: Finerenone can affect kidney function, so it is important to monitor kidney health regularly. Your doctor may adjust your dosage or discontinue the medication if kidney function worsens.
  
  
• Potassium levels: Finerenone can increase potassium levels in the blood, which can be dangerous. Your doctor will monitor your potassium levels and may recommend avoiding potassium-rich foods or supplements.
  
  
• Pregnancy and breastfeeding: Finerenone is not recommended for use during pregnancy or breastfeeding due to potential risks to the baby. If you are pregnant or planning to become pregnant, talk to your doctor before starting treatment with Finerenone.
  
  

Other medical conditions: Before taking Finerenone, inform your doctor if you have heart problems, kidney disease, or any electrolyte imbalances (such as high potassium levels).

Finerenone can interact with other medications, so it’s important to inform your healthcare provider about all the medications you are taking. Some key interactions include:

• Potassium levels: Finerenone can increase potassium levels in the blood, especially if taken with other medications that affect potassium (e.g., potassium supplements, ACE inhibitors, or ARBs).
  
  
• Blood pressure medications: When combined with other medications used to treat high blood pressure, such as ACE inhibitors, angiotensin receptor blockers (ARBs), or diuretics, the blood pressure-lowering effects can be enhanced.
  
  

CYP3A4 inhibitors: Finerenone is metabolized by the CYP3A4 enzyme, so medications that inhibit this enzyme (e.g., ketoconazole, itraconazole, clarithromycin) may increase Finerenone levels in the blood, requiring dose adjustments.

The recommended dosage of Finerenone is:

• 10 mg once daily (for most patients), with an option to increase to 20 mg daily based on individual response and tolerability.
  
  
• The dosage may be adjusted based on kidney function, blood pressure, and potassium levels.
  
  

Always follow your healthcare provider’s instructions and never adjust the dosage without consultation.

Finerenone is a prescription-only medication, which means it must be prescribed by a healthcare provider. Your doctor will assess your medical history, kidney function, heart health, and other factors to determine whether Finerenone is right for you.

• What is Finerenone used for?
  It is used to reduce the risk of kidney and heart complications in adults with:

  • Chronic kidney disease (CKD) associated with type 2 diabetes (T2D).

  • It helps slow kidney damage progression and lower the chance of heart attack, hospitalization for heart failure, or cardiovascular death.

• What are the brand names?
  Kerendia® (U.S. and worldwide).

• What is the active ingredient?
  Finerenone, a non-steroidal mineralocorticoid receptor antagonist (MRA).

• How does Finerenone work?

  • Blocks mineralocorticoid receptors (MRs) in the kidneys, heart, and blood vessels.

  • Overactivation of these receptors causes inflammation and fibrosis that worsen CKD and heart disease.

  • Finerenone helps reduce inflammation, oxidative stress, and scarring, protecting organs from long-term damage.

• What type of medication is it?
  A non-steroidal MRA (mineralocorticoid receptor antagonist) — newer and more selective than older MRAs like spironolactone or eplerenone.

• How is Finerenone taken?

  • By mouth, once daily, with or without food.

  • Swallow tablets whole with water.

  • Usually prescribed alongside ACE inhibitors or ARBs (blood-pressure-lowering kidney-protective drugs).

• What are the available strengths?

  • 10 mg tablets

  • 20 mg tablets

• How long does it take to work?

  • It starts acting on receptors within hours, but kidney and heart benefits appear gradually over months.
