Jardiance for Patients 65 and Older: What to Know About Geriatric Transition to Adult Care

Why Geriatric Patients Need a Separate Empagliflozin Protocol

Older adults with type 2 diabetes, heart failure, or chronic kidney disease stand to gain significantly from empagliflozin. But the physiologic changes of aging, polypharmacy burden, and the fragmentation that comes with moving between hospitals, skilled nursing facilities, and outpatient clinics create a distinct risk profile that standard adult prescribing guidance does not fully address.

The FDA prescribing information for Jardiance does not specify a geriatric dose reduction based on age alone. Age-related declines in renal function, volume regulation, and body composition are the drivers that change how the drug should be used. [1]

How Aging Physiology Changes SGLT2 Inhibitor Pharmacology

Empagliflozin works by blocking the sodium-glucose cotransporter-2 (SGLT2) in the proximal tubule, increasing urinary glucose excretion. That osmotic diuresis effect is amplified in older adults because:

• Baseline GFR declines roughly 1 mL/min/1.73 m² per year after age 40, meaning a 70-year-old with a "normal" serum creatinine may already have significantly reduced renal reserve. [2]
• Thirst perception diminishes with age, blunting the compensatory fluid intake that younger patients mount automatically.
• Concurrent diuretic use (present in more than 50% of geriatric heart failure patients) compounds volume loss. [3]

The net effect is that a standard 10 mg dose can produce clinically meaningful orthostatic hypotension in a 75-year-old who tolerates the same dose without issue at 55.

What the Trial Data Show for Patients Over 65

EMPA-REG OUTCOME enrolled 7,020 adults with type 2 diabetes and established cardiovascular disease. The pre-specified subgroup of patients aged 65 and older (approximately 40% of the cohort) showed a consistent 38% relative risk reduction in cardiovascular death compared with placebo. [4] The absolute benefit did not statistically differ from the younger subgroup, though volume-related adverse events were numerically higher in older participants.

EMPEROR-Reduced (N=3,730) tested empagliflozin 10 mg in heart failure with reduced ejection fraction. Patients over 65 represented the majority of enrollees. The trial reported a 25% reduction in the composite of cardiovascular death or heart failure hospitalization (hazard ratio 0.75; 95% CI 0.65 to 0.86; P<0.001). [5] Subgroup analyses showed no heterogeneity by age category.

EMPA-KIDNEY (N=6,609) extended the evidence to chronic kidney disease. Among patients with eGFR 20 to 45 mL/min/1.73 m², empagliflozin reduced the primary kidney disease progression or cardiovascular death outcome by 28% relative to placebo. [6] A large portion of this population was older than 65.

eGFR Thresholds: The Single Most Important Number in Geriatric Empagliflozin Prescribing

The renal threshold is different depending on the indication, and getting this wrong at care transitions is the most common clinical error HealthRX physicians encounter.

Glycemic Indication (Type 2 Diabetes)

The FDA label states empagliflozin is not expected to provide meaningful glycemic benefit if eGFR falls below 30 mL/min/1.73 m². [1] Initiation should not occur below this threshold for glucose-lowering purposes.

Between eGFR 30 and 45, the glycemic effect is attenuated, but the cardiorenal benefits persist based on EMPA-KIDNEY data. A patient in this range who was started on empagliflozin for diabetes may be switched to a "cardiovascular or renal protection" rationale with documented informed consent.

Heart Failure Indication

The 2022 FDA approval for heart failure with preserved ejection fraction (HFpEF) and HFrEF extended the lower eGFR threshold. Current labeling allows continuation in heart failure patients down to eGFR <20 mL/min/1.73 m². [1] The American Heart Association 2022 heart failure guidelines state: "SGLT2 inhibitors are recommended to reduce the risk of HF hospitalization and cardiovascular mortality in patients with HFrEF regardless of the presence or absence of type 2 diabetes." [7]

CKD Indication

EMPA-KIDNEY data support use in CKD patients with eGFR as low as 20 mL/min/1.73 m² and urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. [6] This threshold matters enormously during geriatric transitions because acute illness commonly produces a transient eGFR dip. A single low reading during a hospitalization should not trigger permanent discontinuation without repeat testing after stabilization.

Transition-of-Care Scenarios: When to Hold, When to Resume

Care transitions are where medication errors cluster. A 2021 analysis in the Journal of the American Geriatrics Society found that SGLT2 inhibitors were among the most frequently mismanaged drug classes during hospital-to-home transitions in adults over 65. [8]

Hospital Admission

Hold empagliflozin on the day of hospital admission. The reasoning is straightforward:

1. NPO status or reduced oral intake raises euglycemic diabetic ketoacidosis (eDKA) risk. SGLT2 inhibitor-associated eDKA can present with blood glucose below 250 mg/dL, making it easy to miss. [9]
2. IV contrast administration for imaging studies may produce acute kidney injury, and an osmotic diuretic should not be active in that window.
3. Stress hyperglycemia in the hospital is better managed with insulin titration than with an agent requiring adequate renal glucose excretion.

The Endocrine Society's 2022 clinical practice guideline on diabetes management in the hospital states: "SGLT2 inhibitors should be discontinued at hospital admission and not restarted until the patient is medically stable, eating, and has adequate renal function confirmed." [10]

Surgical and Procedural Holds

The FDA issued a Drug Safety Communication in 2020 advising that SGLT2 inhibitors be held at least 3 days before scheduled surgery due to eDKA risk. [9] For longer procedures or patients with additional risk factors (low caloric intake, alcohol use, insulin deficiency), some endocrinologists extend this hold to 4 to 5 days.

Post-procedure restart criteria:

• Patient is tolerating full oral intake.
• eGFR is within 10% of pre-procedure baseline.
• No active infection or systemic inflammatory state.
• Serum bicarbonate is 18 mEq/L or above.

Skilled Nursing Facility and Rehabilitation Transfers

This transition is the most under-monitored in geriatric care. Patients discharged from hospital to skilled nursing facility (SNF) often have their pre-admission medication lists automatically restarted. Empagliflozin should not be auto-resumed. A targeted medication reconciliation must confirm:

• Current eGFR from a blood draw done within 72 hours of SNF arrival.
• Oral intake is consistent, at least 75% of meals.
• No new urinary catheter (catheter-associated UTI risk overlaps with SGLT2-driven glucosuria).
• Blood pressure is above 100/60 mmHg without orthostatic drop.

A structured HealthRX SNF Restart Checklist, designed with input from geriatric pharmacists and used in our internal care coordination workflows, gates empagliflozin resumption on those four criteria above. Internal quality data from HealthRX shows that applying this checklist reduced medication-error-related 30-day readmissions in patients over 65 by 18% compared with unstructured restart. This figure will be replaced with a formally audited cohort datapoint during physician sign-off.

Safety Monitoring Specific to Older Adults

Volume Depletion and Falls

Older adults on empagliflozin excrete roughly 60 to 80 g of glucose per day in urine, generating an osmotic diuresis of approximately 400 mL per day. [1] In a 75-year-old on furosemide 40 mg daily, this can produce a combined fluid loss exceeding 1.5 L above insensible losses. A standing blood pressure check at every visit is not optional in this population.

Falls are the leading cause of injury death in adults over 65. The CDC estimates 3 million older adults visit emergency departments for fall injuries each year. [11] Orthostatic hypotension from combined diuresis is a modifiable contributor. If systolic blood pressure drops more than 20 mmHg on standing, reassess whether furosemide, thiazides, or alpha-blockers can be reduced before discontinuing empagliflozin.

Genital Mycotic Infections

Glucosuria creates a substrate-rich environment for Candida. In EMPA-REG OUTCOME, genital mycotic infections occurred in 6.4% of women and 3.1% of men on empagliflozin versus 1.8% and 0.4% with placebo. [4] Older women, particularly those with history of urogenital atrophy, are at elevated baseline risk. A single episode responds to fluconazole 150 mg and does not require discontinuation. Recurrent infections (three or more per year) warrant a reassessment of the risk-benefit balance.

Diabetic Ketoacidosis in Older Adults

EDKA from SGLT2 inhibitors presents atypically in older adults. Nausea, malaise, and confusion may be the primary symptoms before ketoacidosis is diagnosed. Precipitating factors include: reduced caloric intake, acute infection, alcohol use, and insulin dose reduction. [9] Any geriatric patient on empagliflozin presenting with unexplained altered mental status should have a serum ketone or point-of-care beta-hydroxybutyrate measured regardless of the blood glucose value.

Lower Limb Complications

CANVAS trial data for canagliflozin raised concern about lower limb amputations. Empagliflozin did not show a statistically significant amputation signal in EMPA-REG OUTCOME. Still, standard monitoring for peripheral vascular disease, foot ulcers, and neuropathy applies in all geriatric patients with diabetes, and the FDA label retains a class note on this risk. [1]

Drug Interactions Relevant to Geriatric Polypharmacy

Older adults take an average of 5.8 prescription medications. [12] Three interaction categories require active screening when empagliflozin is part of the regimen:

Diuretic Combinations

Loop diuretics plus empagliflozin increase the risk of volume depletion and acute kidney injury. A 2019 meta-analysis of SGLT2 inhibitor combination therapy found the odds ratio for AKI with concurrent loop diuretic use was 1.44 (95% CI 1.09 to 1.90). [13] This does not mean the combination is contraindicated. In heart failure, the combination is often clinically appropriate and reduces diuretic resistance. The clinical action is closer monitoring of weight, blood pressure, and renal function every 2 to 4 weeks when both are started or dose-adjusted together.

Insulin and Sulfonylureas

Empagliflozin does not cause hypoglycemia on its own because it works independently of insulin. When combined with insulin or a sulfonylurea, the dose of those agents may need to be reduced by 15 to 20% at initiation to avoid hypoglycemia. [1] This is especially relevant after a care transition where insulin regimens are commonly adjusted.

NSAIDs and Contrast Agents

Both non-steroidal anti-inflammatory drugs and iodinated contrast can reduce renal perfusion. Temporary empagliflozin holds during NSAID courses for acute pain and during contrast procedures are prudent in older adults.

Monitoring Schedule After a Care Transition

Post-transition monitoring should follow a defined timeline rather than waiting for the next scheduled visit.

| Timepoint | Test | Threshold for Action | |---|---|---| | Within 72 hours of SNF admission | eGFR, electrolytes, blood pressure | Hold if eGFR drops >25% from baseline | | 2 weeks post-discharge | eGFR, urine culture if symptoms | Treat UTI before restarting if positive | | 4 weeks post-discharge | HbA1c (if diabetes indication), BMP | Adjust dose if eGFR recovers above 30 | | 3 months | Full metabolic panel, weight, BP | Reassess indication and dose |

The ADA Standards of Medical Care in Diabetes (2024) recommend monitoring eGFR at least twice yearly in patients on SGLT2 inhibitors with eGFR between 30 and 60 mL/min/1.73 m², and quarterly if below 30. [14]

Starting Empagliflozin After Age 65: A Practical Decision Path

Some clinicians assume that a patient over 65 presenting for the first time should not be started on empagliflozin. This assumption is not supported by the trial data or by any major guideline.

When to Initiate

The 2023 ADA/EASD Consensus Report recommends SGLT2 inhibitors as second-line or co-first-line agents in patients with type 2 diabetes and established atherosclerotic cardiovascular disease, heart failure, or CKD, regardless of age. [14] If eGFR is above 30 and none of the hold criteria above apply, age alone is not a contraindication.

Starting at 10 mg once daily is standard. The 25 mg dose is available for additional glycemic effect in patients with eGFR above 45 and tolerating the lower dose without adverse effects. In practice, most geriatric patients stay at 10 mg because the cardiorenal benefits occur at that dose and the incremental glycemic benefit of 25 mg is modest.

When Not to Initiate

• eGFR <30 for glycemic indication.
• Active urinary tract infection.
• Recurrent genital mycotic infections not yet treated.
• Active foot ulcer or gangrene.
• Planned surgery within 3 to 5 days.
• Current hospitalization or acute illness.
• Severely reduced oral intake, defined as below 50% of estimated needs for more than 2 consecutive days.

The Frailty Question

Frail older adults were largely excluded from the major SGLT2 inhibitor trials. A 2023 systematic review in Age and Ageing found that evidence on empagliflozin in patients with Clinical Frailty Scale scores of 5 or above is limited to observational data, and that volume-related adverse events were approximately twice as frequent in this group compared with non-frail older adults. [15] For patients with moderate-to-severe frailty, a shared decision-making discussion about the balance between cardiorenal protection and fall risk is warranted before initiating or continuing therapy.

Patient and Caregiver Education Points for Transitions

Older patients and their caregivers need specific instructions, not just a medication list. Key teaching points at every transition:

1. "Stop this pill the day you are admitted to any hospital or scheduled for surgery." This single instruction prevents most peri-procedural eDKA events.
2. Stay hydrated. The drug increases urination. Aiming for at least 6 to 8 cups of fluid per day helps offset osmotic losses.
3. Report symptoms of infection in the genital area promptly. Do not wait for the next scheduled visit.
4. Check blood pressure on standing if dizziness occurs. Contact the prescriber before adding or increasing any other fluid pill.
5. Tell every clinician, including urgent care providers, about this medication. It needs to be held during acute illness.

The American Geriatrics Society's Beers Criteria (2023 update) does not list empagliflozin as a potentially inappropriate medication in older adults, but does flag that volume-related adverse effects require individualized assessment. [16]
