Empagliflozin Contraindication Based on CKD Grade
Empagliflozin is contraindicated in patients with severe renal impairment (eGFR <20 mL/min/1.73 m²), end-stage renal disease (ESRD), or patients on dialysis. 1
Current Recommendations for Empagliflozin Use in CKD
The FDA drug label explicitly states that empagliflozin is contraindicated in:
- Severe renal impairment (eGFR <20 mL/min/1.73 m²)
- End-stage renal disease
- Patients on dialysis 1
This represents a significant evolution in guidance, as earlier recommendations were more restrictive:
- In 2019, SGLT2 inhibitors as a class were contraindicated with eGFR <30 mL/min/1.73 m² 2
- By 2022, the American Diabetes Association (ADA) and Kidney Disease: Improving Global Outcomes (KDIGO) consensus report expanded use to eGFR ≥20 mL/min/1.73 m² 2
Evidence Supporting Current Recommendations
The expansion of empagliflozin use to patients with eGFR as low as 20 mL/min/1.73 m² is supported by:
The EMPEROR-Reduced trial, which demonstrated cardiovascular and kidney benefits in heart failure patients with eGFR as low as 20 mL/min/1.73 m² 3
The 2024 ADA Standards of Care, which recommends SGLT2 inhibitors for people with eGFR ≥20 mL/min/1.73 m² and type 2 diabetes, as they slow CKD progression and reduce heart failure risk independent of glucose management 2
Important Considerations for Use in CKD
Efficacy changes: The glucose-lowering effect of empagliflozin diminishes with declining kidney function, but cardiorenal protective benefits persist 2
Continuation below initiation threshold: Once initiated, empagliflozin can be continued at lower levels of eGFR until dialysis is initiated 2
Monitoring: While using empagliflozin in patients with CKD:
- Watch for volume depletion
- Monitor for euglycemic diabetic ketoacidosis
- Consider adjusting other glucose-lowering medications to prevent hypoglycemia
- Educate about genital mycotic infections 2
Practical Application
For patients with type 2 diabetes and CKD:
- eGFR ≥20 mL/min/1.73 m²: Empagliflozin can be initiated and continued
- eGFR <20 mL/min/1.73 m²: Empagliflozin is contraindicated
- Dialysis patients: Empagliflozin is contraindicated
Common Pitfalls to Avoid
Outdated guidance: Earlier recommendations were more restrictive (contraindicated at eGFR <30 mL/min/1.73 m²). Current evidence supports use down to eGFR ≥20 mL/min/1.73 m²
Confusing initiation vs. continuation thresholds: While initiation requires eGFR ≥20 mL/min/1.73 m², once started, empagliflozin can be continued at lower eGFR levels until dialysis
Overlooking non-glycemic benefits: Even when glucose-lowering efficacy is reduced in advanced CKD, cardiovascular and kidney protective benefits persist
This guidance represents a significant evolution in the use of empagliflozin in CKD, with the most recent evidence supporting broader use in patients with reduced kidney function than previously recommended.
