Dapagliflozin Sick Day Plan

Patients on dapagliflozin 10 mg daily should temporarily stop the medication during acute illness with signs of volume depletion (vomiting, diarrhea, reduced fluid intake) and resume it within 24-48 hours after symptoms resolve and normal eating/drinking resumes. 1

When to Stop Dapagliflozin

Triggering Symptoms (Initiate Sick Day Plan)

Stop dapagliflozin when experiencing any of the following signs of volume depletion 1:

  • Vomiting or diarrhea causing significant fluid losses (100% consensus)
  • Nausea or poor appetite resulting in significantly decreased fluid intake (88% consensus)
  • New lightheadedness, dizziness, or fainting, especially when standing (88% consensus)
  • Rapid weight loss (≥3 kg in 2 days) (83% consensus)
  • Decreased urine output (75% consensus)

When to Contact Healthcare Provider Immediately

Seek medical attention if 1:

  • Reduced consciousness or new confusion (100% consensus)
  • Vomiting >4 times in 12 hours or cannot keep fluids down (96% consensus)
  • Low blood pressure (systolic <80 mmHg or drop of 20 mmHg systolic/10 mmHg diastolic) (92% consensus)
  • Moderate or high ketones on testing (91% consensus) - critical for SGLT2 inhibitor users
  • Heart rate increase by 30 bpm (79% consensus)
  • Fever >38°C (101°F) on 2 measurements (75% consensus)

Critical Actions During Sick Days

Monitoring Requirements

  • Check ketones - this is essential for all patients on SGLT2 inhibitors like dapagliflozin (95% consensus) 1
  • Increase fluid intake with limited caffeine; consider electrolyte replacement solutions (92% consensus)
  • Monitor for difficulty breathing, fainting, or falls - these require emergency care (96-100% consensus)

Duration of Medication Hold

  • Stop for up to 3 days maximum (100% consensus) 1
  • Stop until signs and symptoms resolve (88% consensus)
  • If symptoms persist >72 hours, contact healthcare provider (100% consensus)

When to Restart Dapagliflozin

Resume dapagliflozin at the usual 10 mg dose within 24-48 hours of eating and drinking normally (95% consensus) 1. The FDA label supports temporary interruption and resumption when the patient is clinically stable and has resumed oral intake 2.

Self-Management is Appropriate When 1:

  • No severe symptoms present (96% consensus)
  • Patient feels able to cope (92% consensus)
  • Patient can maintain adequate fluid intake (88% consensus)

Critical Safety Considerations

Ketoacidosis Risk

The FDA label explicitly warns that SGLT2 inhibitors like dapagliflozin increase ketoacidosis risk, which can be life-threatening 2. This risk is elevated during acute illness, making temporary discontinuation during sick days particularly important. Fatal events have been reported in patients with type 2 diabetes using SGLT2 inhibitors 2.

Other Medications to Consider Stopping

During the same sick day period, also temporarily stop 1:

  • NSAIDs (95% consensus)
  • Diuretics (loop, thiazide, potassium-sparing) (90-95% consensus)
  • ACE inhibitors/ARBs (90% consensus)
  • Metformin (86% consensus)

These medications share similar risks of acute kidney injury during volume depletion.

Common Pitfalls to Avoid

  1. Don't wait for severe symptoms - initiate the sick day plan early when volume depletion signs first appear
  2. Don't forget ketone monitoring - this is non-negotiable for SGLT2 inhibitor users and can prevent life-threatening ketoacidosis
  3. Don't hold medications indefinitely - resume within 24-48 hours of clinical stability to maintain cardiovascular and renal protective benefits
  4. Don't rely on patient self-reporting alone - implementation studies show patients often fail to report sick days even when they occur 3, so proactive education and follow-up are essential

The 2023 consensus guidelines 1 represent the most comprehensive, evidence-based framework for sick day medication management, achieving 96% expert consensus specifically for SGLT2 inhibitor discontinuation during acute illness.
