When to Hold Dapagliflozin in CKD Based on eGFR
Do not discontinue dapagliflozin solely because eGFR falls below 45 mL/min/1.73 m²; cardiovascular and renal protective benefits persist even when glycemic efficacy is lost. 1
eGFR Thresholds for Initiation vs. Continuation
Initiation Criteria
- Dapagliflozin can be initiated when eGFR ≥25 mL/min/1.73 m² for cardiovascular and renal protection, regardless of diabetes status. 1, 2
- For glycemic control as the primary goal, initiation is not recommended when eGFR <45 mL/min/1.73 m² because glucose-lowering efficacy is significantly reduced at lower eGFR levels. 1
- The 2025 American Diabetes Association guidelines support initiation down to eGFR ≥20 mL/min/1.73 m² for cardiovascular and renal protection, representing the most recent threshold update. 1
Continuation Criteria
- If eGFR falls below 25 mL/min/1.73 m² during treatment, continue dapagliflozin 10 mg daily until dialysis is initiated. 1, 2
- Patients enrolled in DAPA-CKD and DELIVER trials were not required to discontinue therapy when eGFR fell below 25 mL/min/1.73 m², and continuation showed persistent benefit. 2, 3
- The FDA label explicitly states that once enrolled in trials, patients were not required to stop dapagliflozin if eGFR fell below 25 mL/min/1.73 m² or if dialysis was initiated. 2
Evidence Supporting Continuation at Low eGFR
- In a pooled analysis of DAPA-HF and DELIVER trials, 347 patients experienced eGFR deterioration to <25 mL/min/1.73 m², yet dapagliflozin reduced the primary outcome by 47% (HR 0.53,95% CI 0.33-0.83) in this subgroup compared to 22% reduction in those without such deterioration. 3
- The benefit-to-risk ratio favored continuation of dapagliflozin in patients experiencing kidney function deterioration, with no excess safety events between treatment groups. 3
- Dapagliflozin slowed eGFR decline by 0.95 mL/min/1.73 m² per year compared to placebo over a median 2.3-year follow-up in the DAPA-CKD trial. 4
Expected Initial eGFR Changes
- An acute, reversible eGFR decline of 2–5 mL/min/1.73 m² occurs within the first 2–4 weeks, reflecting hemodynamic changes rather than kidney injury. 1, 5
- This initial dip should not prompt discontinuation; it is followed by stabilization and slower long-term decline compared to placebo. 1, 4
- Recheck eGFR 1–2 weeks after initiation to document the expected transient decrease. 1
Temporary Discontinuation Scenarios (Not Based on eGFR)
Sick Day Rules
- Withhold dapagliflozin during acute illness with reduced oral intake, fever, vomiting, or diarrhea to prevent volume depletion and euglycemic diabetic ketoacidosis. 1
- Stop at least 3 days before major surgery or procedures requiring prolonged fasting. 1
- Resume only after normal oral intake is re-established and the patient has recovered from acute illness. 1
Volume Depletion Assessment
- If eGFR decreases >30% from baseline AND there are signs of hypovolemia, reduce diuretic doses first before considering dapagliflozin adjustment. 1
- Assess volume status before initiation and correct any depletion; consider temporary diuretic dose reduction in high-risk patients. 1
Common Pitfalls to Avoid
- Do not stop dapagliflozin when eGFR falls between 25–44 mL/min/1.73 m²; the 10 mg dose remains appropriate for cardiovascular and renal protection despite loss of glycemic efficacy. 1
- Do not discontinue in response to the expected early eGFR dip in the first 2–4 weeks; this change is hemodynamic and reversible. 1
- Do not reduce the dose below 10 mg for cardiovascular or renal indications at any eGFR level; all outcome trials used the fixed 10 mg dose. 1
- Do not withhold ACE inhibitors or ARBs when continuing dapagliflozin; 98.1% of DAPA-CKD participants were on renin-angiotensin-aldosterone system inhibitors with additive renal protection. 6
Safety Monitoring During Continuation
- Monitor for genital mycotic infections (occur in approximately 6% of patients vs. 1% with placebo) and counsel on daily hygiene. 1
- Warn about euglycemic diabetic ketoacidosis risk; instruct patients to seek immediate care for malaise, nausea, vomiting, or abdominal pain even when blood glucose is normal. 1
- In insulin-requiring patients, maintain at least low-dose insulin even when dapagliflozin is temporarily held during illness. 1
