- Sodium-Glucose Cotransporter 2 (SGLT2) Inhibitor
Ertugliflozin: By inhibiting sodium-glucose cotransporter 2 (SGLT2) in the proximal renal tubules, ertugliflozin reduces reabsorption of filtered glucose from the tubular lumen and lowers the renal threshold for glucose (RTG). SGLT2 is the main site of filtered glucose reabsorption; reduction of filtered glucose reabsorption and lowering of RTG result in increased urinary excretion of glucose, thereby reducing plasma glucose concentrations.
Metformin: Decreases hepatic glucose production, decreasing intestinal absorption of glucose and improves insulin sensitivity (increases peripheral glucose uptake and utilization).
Use: Labeled Indications
Diabetes mellitus, type 2, treatment: As an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus who are not adequately controlled on a regimen containing ertugliflozin or metformin or who are already treated with both ertugliflozin and metformin
History of serious hypersensitivity to ertugliflozin, metformin, or any component of the formulation; severe renal impairment (eGFR <30 mL/minute/1.73 m2), end-stage renal disease, or dialysis; acute or chronic metabolic acidosis (including diabetic ketoacidosis, with or without coma).
Canadian labeling: Additional contraindications (not in US labeling): Unstable and/or insulin-dependent (type 1) diabetes mellitus; history of lactic acidosis; eGFR <45 mL/minute/1.73 m2; excessive alcohol intake (acute or chronic); severe hepatic dysfunction or clinical or laboratory evidence of hepatic disease; cardiovascular collapse and disease states associated with hypoxemia (eg, cardiorespiratory insufficiency); stressful conditions (eg, severe infections, trauma, surgery); severe dehydration or shock; during period around administration of iodinated contrast; pregnancy; breastfeeding.
Note: Hypovolemia, if present, should be corrected prior to initiating treatment. May require a gradual dose reduction of insulin and/or insulin secretagogues to avoid hypoglycemia.
Diabetes mellitus, type 2, treatment: Oral:
Note: Additional therapeutic considerations may apply; refer to individual agents for information.
Initial: Individualize initial dose based on patient's current antidiabetic regimen. May gradually increase dose based on effectiveness and tolerability.
Patients initiating ertugliflozin and already taking metformin: Ertugliflozin 5 mg/day plus a similar total daily dose of metformin, administered in 2 divided doses.
Patients initiating metformin and already taking ertugliflozin: Metformin 1 g/day plus a similar total daily dose of ertugliflozin, administered in 2 divided doses.
Patients already taking ertugliflozin and metformin: Administer the same total daily dose of ertugliflozin and a similar total daily dose of metformin in 2 divided doses.
Maximum: Ertugliflozin 15 mg/metformin 2 g per day.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Refer to adult dosing. Metformin initial and maintenance dosing should be conservative, due to the potential for decreased renal function (monitor).
Oral: Administer twice daily with meals.
Individualized medical nutrition therapy based on American Diabetes Association recommendations is an integral part of therapy. Metformin may cause GI upset; take with food (to decrease GI upset). Monitor for signs and symptoms of vitamin B12 and/or folic acid deficiency; supplementation may be required.

ALERT: U.S. Boxed WarningLactic acidosis:
Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. The onset of metformin-associated lactic acidosis is often subtle, accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Metformin-associated lactic acidosis was characterized by elevated blood lactate levels (>5 mmol/L), anion gap acidosis (without evidence of ketonuria or ketonemia), an increased lactate/pyruvate ratio, and metformin plasma levels generally >5 mcg/mL.
Risk factors for metformin-associated lactic acidosis include renal impairment, concomitant use of certain drugs (eg, carbonic anhydrase inhibitors such as topiramate), age ≥65 years old, having a radiological study with contrast, surgery and other procedures, hypoxic states (eg, acute congestive heart failure), excessive alcohol intake, and hepatic impairment.
Steps to reduce the risk of and manage metformin-associated lactic acidosis in these high risk groups are provided in the Full Prescribing Information.
If metformin-associated lactic acidosis is suspected, discontinue ertugliflozin/metformin and institute general supportive measures in a hospital setting. Prompt hemodialysis is recommended.
Concerns related to adverse effects:
• Bone fractures: An increased incidence of bone fractures has been observed with other sodium-glucose cotransporter 2 (SGLT2) inhibitors in some clinical trials. A placebo-controlled trial with ertugliflozin conducted over 2 years did not demonstrate an increased fracture risk; similar changes in bone mineral density (BMD) were observed between groups, except at the hip where a greater decrease in BMD was observed with ertugliflozin (Gallo 2019).
• Genital mycotic infections: Ertugliflozin may increase the risk of genital mycotic infections (eg, vulvovaginal mycotic infection, vulvovaginal candidiasis, vulvovaginitis, candida balanitis, balanoposthitis). Patients with a history of these infections or uncircumcised males are at greater risk.
• Hypotension: Ertugliflozin may cause symptomatic hypotension due to intravascular volume depletion especially in patients with renal impairment (ie, eGFR <60 mL/minute/1.73 m2), elderly, patients on other antihypertensives (eg, diuretics, angiotensin-converting enzyme (ACE) inhibitors, or angiotensin receptor blockers [ARBs]), or those with low systolic blood pressure. Assess volume status prior to initiation in patients at risk of hypotension and correct if depleted; monitor for signs and symptoms of hypotension after initiation.
• Ketoacidosis: Cases of ketoacidosis (some fatal) have been reported in patients with type 1 and type 2 diabetes mellitus receiving SGLT2 inhibitors; in some cases, patients have presented with normal or only modestly elevated blood glucose (<250 mg/dL). Before initiating treatment, consider risk factors that may predispose to ketoacidosis (eg, pancreatic insulin deficiency, dose decreases of insulin, caloric restriction, alcohol abuse, acute febrile illness, surgery, any other extreme stress event). Consider temporary discontinuation of therapy at least 4 days prior to surgery or any event that may precipitate ketoacidosis; ensure risk factors are resolved prior to reinitiating therapy. Patients presenting with nausea/vomiting, abdominal pain, generalized malaise, and/or shortness of breath should be assessed immediately for ketoacidosis; discontinue therapy and treat promptly if ketoacidosis is suspected.
• Lactic acidosis: [US Boxed Warning]: Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. The onset is often subtle, accompanied by nonspecific symptoms (eg, malaise, myalgias, respiratory distress, somnolence, abdominal pain); elevated blood lactate levels (>5 mmol/L); anion gap acidosis (without evidence of ketonuria or ketonemia); increased lactate:pyruvate ratio; metformin plasma levels generally >5 mcg/mL. Risk factors for lactic acidosis include patients with renal impairment, concomitant use of certain drugs (eg, carbonic anhydrase inhibitors such as topiramate), ≥65 years of age, having a radiologic study with contrast, surgery and other procedures, hypoxic states (eg, acute heart failure), excessive alcohol intake, and hepatic impairment. Discontinue immediately if lactic acidosis is suspected; prompt hemodialysis is recommended. Lactic acidosis should be suspected in any patient with diabetes receiving metformin with evidence of acidosis but without evidence of ketoacidosis. Discontinue use in patients with conditions associated with dehydration, hypoperfusion, sepsis, or hypoxemia. Temporarily discontinue therapy in patients with restricted food and fluid intake. The risk of accumulation and lactic acidosis increases with the degree of impairment of renal function.
• Lower limb amputation: There are conflicting data involving the risk of lower limb amputations with SGLT2 inhibitor therapy. Canagliflozin was associated with almost a 2-fold increased risk of lower limb amputations compared to placebo in the CANVAS and CANVAS-R trials, which included patients with type 2 diabetes at high cardiovascular risk (Neal 2017). Similar analyses with ertugliflozin have not yet been published. The following FDA guidance (developed specifically for canagliflozin) may reasonably apply to use of other SGLT2 inhibitors: Prior to initiation consider risk factors for amputation including prior amputation, peripheral vascular disease, neuropathy, and diabetic foot ulcers. Counsel patients about the importance of preventative foot care. Discontinue therapy if any of the following occur: signs and symptoms of new infection (including osteomyelitis), new pain or tenderness, or sores/ulcers involving the lower limbs (FDA Drug Safety Communication 2017).
• Necrotizing fasciitis: Cases of necrotizing fasciitis of the perineum (Fournier gangrene), a rare but serious and potentially fatal infection, have been reported in patients receiving SGLT2 inhibitors. Assess patients presenting with fever or malaise along with genital or perianal pain, tenderness, erythema, or swelling for necrotizing fasciitis. Discontinue in patients who develop necrotizing fasciitis and initiate treatment immediately.
• Renal effects: Acute kidney injury has been reported with SGLT2 inhibitors. Prior to initiation, consider risk factors for acute kidney injury (eg, hypovolemia, chronic renal insufficiency, heart failure, use of concomitant medications [eg, diuretics, ACE inhibitors, ARBs, or NSAIDs]). Temporarily discontinue use with reduced oral intake or fluid losses; discontinue use if acute kidney injury occurs. Additional abnormalities in renal function (decreased eGFR, increased serum creatinine) and adverse effects related to renal function may occur. Assess renal function prior to initiation and periodically during treatment.
• Urinary tract infection: Serious urinary infections including urosepsis and pyelonephritis requiring hospitalization have been reported; treatment with SGLT2 inhibitors increase the risk for urinary tract infections (UTI); monitor for signs and symptoms of UTI and treat as needed.
• Vitamin B12 concentrations: Long-term metformin use is associated with vitamin B12 deficiency; monitor vitamin B12 serum concentrations periodically with long-term therapy. Monitoring of B12 serum concentrations should be considered in all patients receiving metformin and in particular those with peripheral neuropathy or anemia (ADA 2020).
• Bariatric surgery:
– Altered absorption: Absorption may be altered given the anatomic and transit changes created by gastric bypass and sleeve gastrectomy surgery. ER tablets may have a reduced effect after gastric bypass or sleeve gastrectomy due to the direct bypass of the stomach and proximal small bowel with gastric bypass or a more rapid gastric emptying and proximal small bowel transit with sleeve gastrectomy (Mechanick 2013; Melissas 2013). After gastric bypass (Roux-en-Y gastric bypass [RYGB]), administration of IR tablets led to increased absorption (AUC0-∞ increased by 21%) and bioavailability (increased by 50%) (Padwal 2011). Lactate levels decrease after gastric bypass (RYGB)-induced weight loss irrespective of the use of metformin. Routinely lowering metformin dose after gastric bypass is not necessary as long as normal renal function is preserved (Deden 2018).
– Dehydration: Evaluate, correct, and maintain postsurgical fluid requirements and volume status prior to initiating therapy and closely monitor the patient for the duration of therapy; volume depletion and related adverse events (eg, hypotension, orthostatic hypotension, syncope) have occurred. Fluid intake may be more difficult after gastric bypass, sleeve gastrectomy, and gastric band (Mechanick 2013).
– Euglycemic diabetic ketoacidosis: Discontinue therapy 3 to 5 days prior to surgery (Bobart 2016). Postoperatively, assess volume status, caloric intake, and need for diabetes treatment and withhold antidiabetic medication if type 2 diabetes is in remission. Ketoacidosis has been reported in patients with type 1 and type 2 diabetes on SGLT2 inhibitors. In some cases, normal or only modestly elevated blood glucose was present (<250 mg/dL) (van Niekerk 2018). Risk factors include significant reduction in insulin, caloric restriction, stress of surgery, and infection.
• Heart failure: Metformin may be used in patients with stable heart failure (HF); avoid use in unstable or hospitalized patients with HF (ADA 2020). Risk of lactic acidosis may be increased secondary to hypoperfusion. In a scientific statement from the American Heart Association, metformin has been determined to be an agent that may exacerbate underlying myocardial dysfunction (magnitude: major) (AHA [Page 2016]). Use of metformin in patients with HF may be associated with reduced mortality and reduction in hospital readmission for HF (Crowley 2017; Eurich 2013).
• Hepatic impairment: The manufacturer recommends to generally avoid use in patients with hepatic impairment due to potential for lactic acidosis. However, continued use of metformin in patients with diabetes with liver dysfunction, including cirrhosis, may be associated with a survival benefit in carefully selected patients (Brackett 2010; Crowley 2017; Zhang 2014).
• Renal impairment: Metformin is substantially excreted by the kidney; assess renal function prior to initiation of therapy and periodically thereafter using estimated glomerular filtration rate (eGFR); the risk of metformin accumulation and lactic acidosis increases with degree of renal impairment. Use of concomitant medications that may affect renal function (ie, affect tubular secretion) may also affect metformin disposition. Metformin should be withheld in patients with dehydration and/or prerenal azotemia. Glycemic efficacy of ertugliflozin may be decreased in renal impairment. Use of ertugliflozin/metformin is not recommended if eGFR is between 30 to 60 mL/minute/1.73 m2 prior to initiation of therapy or if persistently in this range during therapy. Use is contraindicated in patients with eGFR <30 mL/minute/1.73 m2, ESRD, or maintained on dialysis.
• Stress-related states: It may be necessary to discontinue metformin and administer insulin if the patient is exposed to stress (fever, trauma, infection, surgery).
• Elderly: Use with caution; risk of metformin associated lactic acidosis increases with age. Risk of intravascular volume depletion, renal impairment, and UTI may be increased in elderly patients.
• Appropriate use: Not indicated for use in patients with type 1 diabetes mellitus or with diabetic ketoacidosis (DKA).
• Ethanol use: Instruct patients to avoid excessive acute or chronic ethanol use; ethanol may potentiate metformin's effect on lactate metabolism.
• Hospitalized patients: Use of SGLT2 inhibitors is not routinely recommended for hospitalized patients (ADA 2020).
• Iodinated contrast: According to the manufacturer, it is recommended to temporarily discontinue metformin at the time of or before iodinated contrast imaging procedures in patients with an eGFR 30 to 60 mL/minute/1.73 m2; or with a history of hepatic disease, alcoholism, or heart failure; or in patients who will receive intra-arterial iodinated contrast. Reevaluate eGFR 48 hours after imaging procedure; restart if renal function is stable. Alternatively, the American College of Radiology (ACR) guidelines recommend that metformin may be used prior to or following administration of iodinated contrast media in patients with no evidence of acute kidney injury (AKI) and with an eGFR ≥30 mL/minute/1.73 m2; ACR guidelines recommend temporary discontinuation of metformin in patients with known AKI or severe chronic kidney disease (stage IV or V [ie, eGFR <30 mL/minute/1.73 m2]) or who are undergoing arterial catheter studies (ACR 2017).
• Patient education: Diabetes self-management education is essential to maximize the effectiveness of therapy.
• Surgical procedures: Consider temporary discontinuation of ertugliflozin-containing products at least 4 days prior to surgery; ensure risk factors for ketoacidosis are resolved prior to reinitiating therapy.
HbA1c (at least twice yearly in patients who have stable glycemic control and are meeting treatment goals; quarterly in patients not meeting treatment goals or with therapy change [ADA 2020]); plasma glucose. Initial and periodic monitoring of hematologic parameters (eg, Hb/Hct and RBC indices); renal function (eGFR) prior to therapy initiation and at least annually (more often in patients at risk of developing renal impairment; every 3 to 6 months if eGFR 45 to <60 mL/minute/1.73 m2; every 3 months if eGFR 30 to <45 mL/minute/1.73 m2 [Lipska 2011]). Monitor vitamin B12 serum concentrations periodically with long-term therapy; folate (if megaloblastic anemia is suspected); volume status (eg, BP, Hct, electrolytes); signs and symptoms of genital mycotic infections and urinary tract infection; lower limb and feet (sores, ulcers, infection); if signs/symptoms of ketoacidosis (eg, nausea/vomiting, abdominal pain, malaise, shortness of breath), confirm diagnosis by direct measurement of blood ketones and arterial pH (measurement of serum bicarbonate or urinary ketones may not be adequate) (AACE [Handelsman 2016]).
Metformin crosses the placenta (ADA 2020). Refer to individual monographs for additional information.
