How does Jardiance (empagliflozin) affect the kidneys?
Jardiance is an SGLT2 inhibitor. By lowering blood sugar and changing how the kidneys handle glucose and sodium, SGLT2 inhibitors can reduce strain on the kidneys. In many patients, that kidney-protective effect translates into slower progression of chronic kidney disease (CKD) and fewer kidney-related complications than with older approaches. (This is the main reason Jardiance is used in kidney disease settings beyond diabetes control.)
Can Jardiance help people with CKD, even if they don’t have diabetes?
Yes. Drugs in the SGLT2 inhibitor class are commonly used to help slow CKD progression in people with CKD, including those with and without diabetes, depending on the specific indication and how advanced the kidney disease is. What’s allowed (and what dose you can use) depends on kidney function at the time treatment starts and local prescribing guidance.
Who should be cautious with Jardiance if they have kidney problems?
The biggest caution points are tied to how much kidney function the person has, because it affects both effectiveness and safety risk. Clinicians typically pay close attention to:
- Current kidney function (estimated glomerular filtration rate, eGFR)
- Dehydration risk (vomiting, diarrhea, poor oral intake)
- Use of diuretics (“water pills”) or other blood-pressure medicines
- History of frequent urinary/genital infections
- Past episodes of ketoacidosis or conditions that increase that risk
What side effects matter most for kidney patients?
The side effects that matter most in people with kidney problems are usually the ones that can worsen dehydration or trigger dangerous metabolic problems:
- Genital yeast infections or urinary infections
- Volume depletion (dizziness, low blood pressure), especially if fluid intake is poor
- Rare ketoacidosis (often with only moderately elevated glucose), particularly during illness, fasting, or low-carb intake
- Changes in kidney blood test results early after starting (sometimes expected to some degree as fluid and kidney-hemodynamics adjust)
Patients are often advised to hold the medication during acute illness that raises dehydration risk (commonly called “sick day rules”), then restart when drinking normally again—your clinician should give you your specific instructions.
What happens to kidney function after starting Jardiance?
With SGLT2 inhibitors, an early, modest change in kidney lab values can happen after initiation. In many patients, long-term kidney outcomes still improve compared with alternatives. The key is monitoring kidney function after starting or adjusting the dose, especially if you already have CKD, are older, or take diuretics.
When should Jardiance be avoided due to kidney function?
Prescribing depends on eGFR and the indication. If kidney function is very low, the medication may not provide the expected glucose-lowering effect, and the risk/benefit balance can change. Whether it’s still used for kidney protection at low eGFR depends on the specific guideline and label for your country and the indication your clinician is targeting.
Does Jardiance interact with other medicines that affect the kidneys?
Yes, kidney patients often use combinations that can shift risk, including:
- Diuretics (more dehydration/low blood pressure risk)
- ACE inhibitors or ARBs (often used for kidney protection in diabetes/CKD, but blood pressure and labs still need monitoring)
- NSAIDs (can worsen kidney function in some situations, especially with dehydration)
- Other glucose-lowering drugs (low blood sugar risk depends on what else you take)
A clinician will usually check blood pressure, hydration status, and kidney labs after starting or changing therapies.
If kidney problems worsen on Jardiance, what should a patient do?
If you develop symptoms that suggest dehydration (significant vomiting/diarrhea, inability to drink), low blood pressure (fainting, severe dizziness), or symptoms of ketoacidosis (nausea, abdominal pain, fast breathing, unusual fatigue), you should contact a clinician right away. In many situations, Jardiance is temporarily stopped during the acute illness and restarted only after recovery per your clinician’s instructions.
