Assess renal function before initiating and as clinically indicated. Assess volume status and correct volume depletion before initiating. Individualize the starting dosage based on the patient's current regimen and renal function. ( 2.2 , 2.3 , 2.4 ) The maximum recommended dosage is 25 mg/day of empagliflozin and 2,000 mg/day of metformin HCl. Initiation of SYNJARDY or SYNJARDY XR is not recommended in patients with an eGFR less than 45 mL/min/1.73 m 2 , due to the metformin HCl component. SYNJARDY: take orally twice daily with meals, with gradual dosage escalation to reduce the gastrointestinal adverse reactions due to metformin HCl. SYNJARDY XR: take orally once daily with a meal in the morning, with gradual dosage escalation to reduce the gastrointestinal adverse reactions due to metformin HCl. Swallow whole; do not split, crush, dissolve, or chew. SYNJARDY or SYNJARDY XR may need to be discontinued at time of, or prior to, iodinated contrast imaging procedures. Withhold SYNJARDY or SYNJARDY XR at least 3 days, if possible, prior to surgery or procedures associated with prolonged fasting

Testing Prior to Initiation of SYNJARDY or SYNJARDY XR Assess renal function before initiating SYNJARDY or SYNJARDY XR and as clinically indicated . Assess volume status. In patients with volume depletion, correct this condition before initiating SYNJARDY or SYNJARDY XR

Recommended Dosage and Administration of SYNJARDY or SYNJARDY XR in Adults When switching to SYNJARDY or SYNJARDY XR from: Metformin HCl: initiate SYNJARDY or SYNJARDY XR at a similar total daily dosage of metformin HCl and a total daily empagliflozin dosage of 10 mg. Empagliflozin: initiate SYNJARDY or SYNJARDY XR at the same total daily dosage of empagliflozin and a total daily metformin HCl dosage of 1,000 mg. Empagliflozin and metformin HCl: initiate SYNJARDY or SYNJARDY XR at the same total daily dosages of each component. Recommended dosage of SYNJARDY or SYNJARDY XR: The recommended total daily dosage of empagliflozin is 10 mg. For additional glycemic control, empagliflozin may be increased to a maximum total daily dosage of 25 mg in patients tolerating 10 mg daily and metformin HCl may be increased to a maximum total daily dosage of 2,000 mg, with gradual escalation to reduce gastrointestinal adverse reactions with metformin HCl . Take SYNJARDY orally twice daily with meals. Take SYNJARDY XR orally once daily with a meal in the morning. Swallow each tablet whole. Do not split, crush, dissolve, or chew

Recommended Dosage and Administration of SYNJARDY in Pediatric Patients Aged 10 Years and Older Individualize the dosage of SYNJARDY based on the patient's current regimen. Monitor effectiveness and tolerability, and adjust dosage as appropriate, not to exceed the maximum total daily dosage of empagliflozin 25 mg and metformin HCl 2,000 mg . Take SYNJARDY orally twice daily with meals; with gradual dose escalation to reduce gastrointestinal adverse reactions with metformin HCl

Dosage Recommendations in Patients with Renal Impairment Initiation of SYNJARDY or SYNJARDY XR is not recommended in patients with an eGFR less than 45 mL/min/1.73 m 2 , due to the metformin HCl component. SYNJARDY and SYNJARDY XR are contraindicated in patients with an eGFR less than 30 mL/min/1.73 m 2

Discontinuation for Iodinated Contrast Imaging Procedures Discontinue SYNJARDY or SYNJARDY XR at the time of, or prior to, an iodinated contrast imaging procedure in patients with an eGFR less than 60 mL/min/1.73 m 2 ; in patients with a history of liver disease, alcoholism or heart failure; or in patients who will be administered intra-arterial iodinated contrast. Re-evaluate eGFR 48 hours after the imaging procedure; restart SYNJARDY or SYNJARDY XR if renal function is stable

Temporary Interruption for Surgery Withhold SYNJARDY or SYNJARDY XR for at least 3 days, if possible, prior to surgery or procedures associated with prolonged fasting. Resume SYNJARDY or SYNJARDY XR when the patient is clinically stable and has resumed oral intake

Recommendations Regarding Missed Dose If a dose is missed, instruct patients to take the dose as soon as possible. Advise patients not to double up the next dose.

Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis: Consider ketone monitoring in patients at risk of ketoacidosis, as indicated. Assess for ketoacidosis regardless of presenting blood glucose levels and discontinue SYNJARDY or SYNJARDY XR if ketoacidosis is suspected. Monitor patients for resolution of ketoacidosis before restarting. Volume Depletion: Before initiating SYNJARDY or SYNJARDY XR, assess volume status and renal function in patients with impaired renal function, elderly patients, or patients on loop diuretics. Monitor for signs and symptoms during therapy. Genitourinary Infections, including Urosepsis, Pyelonephritis, Necrotizing Fasciitis of the Perineum (Fournier's Gangrene), and Genital Mycotic Infections: Monitor patients for signs and symptoms of genitourinary infections and treat promptly, if indicated. Immediately evaluate patients presenting with pain or tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise, for necrotizing fasciitis and if suspected, discontinue SYNJARDY or SYNJARDY XR, and promptly institute appropriate medical and/or surgical intervention. Hypoglycemia: Adult patients taking an insulin secretagogue or insulin may have an increased risk of hypoglycemia. In pediatric patients 10 years of age and older, the risk of hypoglycemia was higher regardless of insulin use. Consider lowering the dosage of insulin secretagogue or insulin to reduce the risk of hypoglycemia when initiating SYNJARDY or SYNJARDY XR. Lower Limb Amputation: Monitor patients for infections or ulcers of lower limbs, and institute appropriate treatment. Hypersensitivity Reactions: Serious hypersensitivity reactions (e.g., angioedema) have occurred with empagliflozin. If hypersensitivity reactions occur, discontinue SYNJARDY or SYNJARDY XR, treat promptly, and monitor until signs and symptoms resolve. Vitamin B 12 Deficiency: Metformin may lower vitamin B 12 levels. Measure hematologic parameters annually and vitamin B 12 at 2 to 3 year intervals and manage any abnormalities. 5.1 Lactic Acidosis There have been postmarketing cases of metformin-associated lactic acidosis, including fatal cases. These cases had a subtle onset and were accompanied by nonspecific symptoms such as malaise, myalgias, abdominal pain, respiratory distress, or increased somnolence; however, hypothermia, hypotension, and resistant bradyarrhythmias have occurred with severe acidosis. Metformin-associated lactic acidosis was characterized by elevated blood lactate concentrations (>5 mmol/Liter), anion gap acidosis (without evidence of ketonuria or ketonemia), and an increased lactate:pyruvate ratio; metformin plasma levels generally >5 mcg/mL. Metformin decreases liver uptake of lactate increasing lactate blood levels which may increase the risk of lactic acidosis, especially in patients at risk. If metformin-associated lactic acidosis is suspected, general supportive measures should be instituted promptly in a hospital setting, along with immediate discontinuation of SYNJARDY or SYNJARDY XR. In SYNJARDY or SYNJARDY XR-treated patients with a diagnosis or strong suspicion of lactic acidosis, prompt hemodialysis is recommended to correct the acidosis and remove accumulated metformin (metformin is dialyzable, with a clearance of up to 170 mL/minute under good hemodynamic conditions). Hemodialysis has often resulted in reversal of symptoms and recovery . Educate patients and their families about the symptoms of lactic acidosis and if these symptoms occur instruct them to discontinue SYNJARDY or SYNJARDY XR and report these symptoms to their healthcare provider. For each of the known and possible risk factors for metformin-associated lactic acidosis, recommendations to reduce the risk of and manage metformin-associated lactic acidosis are provided below: Renal Impairment: The postmarketing metformin-associated lactic acidosis cases primarily occurred in patients with significant renal impairment. The risk of metformin accumulation and metformin-associated lactic acidosis increases with the severity of renal impairment because metformin is substantially excreted by the kidney. Clinical recommendations based upon the patient's renal function include : Before initiating SYNJARDY or SYNJARDY XR, obtain an estimated glomerular filtration rate (eGFR). SYNJARDY and SYNJARDY XR are contraindicated in patients with an eGFR below 30 mL/min/1.73 m 2 . Obtain an eGFR at least annually in all patients taking SYNJARDY or SYNJARDY XR. In patients at increased risk for the development of renal impairment (e.g., the elderly), renal function should be assessed more frequently. Drug Interactions: The concomitant use of SYNJARDY or SYNJARDY XR with specific drugs may increase the risk of metformin-associated lactic acidosis: those that impair renal function, result in significant hemodynamic change, interfere with acid-base balance or increase metformin accumulation . Therefore, consider more frequent monitoring of patients. Age 65 or Greater: The risk of metformin-associated lactic acidosis increases with the patient's age because elderly patients have a greater likelihood of having hepatic, renal, or cardiac impairment than younger patients. Assess renal function more frequently in elderly patients . Radiological Studies with Contrast: Administration of intravascular iodinated contrast agents in metformin-treated patients has led to an acute decrease in renal function and the occurrence of lactic acidosis. Stop SYNJARDY or SYNJARDY XR at the time of, or prior to, an iodinated contrast imaging procedure in patients with an eGFR less than 60 mL/min/1.73 m 2 ; in patients with a history of hepatic impairment, alcoholism, or heart failure; or in patients who will be administered intra-arterial iodinated contrast. Re-evaluate eGFR 48 hours after the imaging procedure, and restart SYNJARDY or SYNJARDY XR if renal function is stable. Surgery and Other Procedures: Withholding of food and fluids during surgical or other procedures may increase the risk for volume depletion, hypotension and renal impairment. SYNJARDY or SYNJARDY XR should be temporarily discontinued while patients have restricted food and fluid intake. Hypoxic States: Several of the postmarketing cases of metformin-associated lactic acidosis occurred in the setting of acute congestive heart failure (particularly when accompanied by hypoperfusion and hypoxemia). Cardiovascular collapse (shock), acute myocardial infarction, sepsis, and other conditions associated with hypoxemia have been associated with lactic acidosis and may also cause prerenal azotemia. When such events occur, discontinue SYNJARDY or SYNJARDY XR. Excessive Alcohol Intake: Alcohol potentiates the effect of metformin on lactate metabolism and this may increase the risk of metformin-associated lactic acidosis. Warn patients against excessive alcohol intake while receiving SYNJARDY or SYNJARDY XR. Hepatic Impairment: Patients with hepatic impairment have developed cases of metformin-associated lactic acidosis. This may be due to impaired lactate clearance resulting in higher lactate blood levels. Therefore, avoid use of SYNJARDY or SYNJARDY XR in patients with clinical or laboratory evidence of hepatic disease

Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis In patients with type 1 diabetes mellitus, empagliflozin, a component of SYNJARDY or SYNJARDY XR, significantly increases the risk of diabetic ketoacidosis, a life-threatening event, beyond the background rate. In placebo-controlled trials of patients with type 1 diabetes mellitus, the risk of ketoacidosis was markedly increased in patients who received sodium glucose co-transporter 2 (SGLT2) inhibitors compared to patients who received placebo and fatal ketoacidosis has occurred with empagliflozin. SYNJARDY and SYNJARDY XR are not indicated for glycemic control in patients with type 1 diabetes mellitus. Type 2 diabetes mellitus and pancreatic disorders (e.g., history of pancreatitis or pancreatic surgery) are also risk factors for ketoacidosis. There have been postmarketing reports of fatal events of ketoacidosis in patients with type 2 diabetes mellitus using SGLT2 inhibitors, including SYNJARDY or SYNJARDY XR. Precipitating conditions for diabetic ketoacidosis or other ketoacidosis include under-insulinization due to insulin dose reduction or missed insulin doses, acute febrile illness, reduced caloric intake, ketogenic diet, surgery, volume depletion, and alcohol abuse. Signs and symptoms are consistent with dehydration and severe metabolic acidosis and include nausea, vomiting, abdominal pain, generalized malaise, and shortness of breath. Blood glucose levels at presentation may be below those typically expected for diabetic ketoacidosis (e.g., less than 250 mg/dL). Ketoacidosis and glucosuria may persist longer than typically expected. Urinary glucose excretion persists for 3 days after discontinuing SYNJARDY or SYNJARDY XR ; however, there have been postmarketing reports of ketoacidosis and/or glucosuria lasting greater than 6 days and some up to 2 weeks after discontinuation of SGLT2 inhibitors. Consider ketone monitoring in patients at risk for ketoacidosis if indicated by the clinical situation. Assess for ketoacidosis regardless of presenting blood glucose levels in patients who present with signs and symptoms consistent with severe metabolic acidosis. If ketoacidosis is suspected, discontinue SYNJARDY or SYNJARDY XR, promptly evaluate, and treat ketoacidosis, if confirmed. Monitor patients for resolution of ketoacidosis before restarting SYNJARDY or SYNJARDY XR. Withhold SYNJARDY or SYNJARDY XR, if possible, in temporary clinical situations that could predispose patients to ketoacidosis. Resume SYNJARDY or SYNJARDY XR when the patient is clinically stable and has resumed oral intake . Educate all patients on the signs and symptoms of ketoacidosis and instruct patients to discontinue SYNJARDY or SYNJARDY XR and seek medical attention immediately if signs and symptoms occur

Volume Depletion Empagliflozin can cause intravascular volume depletion which may sometimes manifest as symptomatic hypotension or acute transient changes in creatinine . There have been post-marketing reports of acute kidney injury, some requiring hospitalization and dialysis, in patients with type 2 diabetes mellitus receiving SGLT2 inhibitors, including empagliflozin. Patients with impaired renal function (eGFR less than 60 mL/min/1.73 m 2 ), elderly patients, or patients on loop diuretics may be at increased risk for volume depletion or hypotension. Before initiating SYNJARDY or SYNJARDY XR in patients with one or more of these characteristics, assess volume status and renal function. In patients with volume depletion, correct this condition before initiating SYNJARDY or SYNJARDY XR. Monitor for signs and symptoms of volume depletion, and renal function after initiating therapy

Genitourinary Infections, including Urosepsis, Pyelonephritis, Necrotizing Fasciitis of the Perineum (Fournier's Gangrene), and Genital Mycotic Infections Empagliflozin increases urinary glucose excretion and increases the risk of genitourinary infections including urinary tract infections and genital mycotic infections in both male and female patients . Serious genitourinary infections, including urosepsis, pyelonephritis, and necrotizing fasciitis of the perineum (Fournier's gangrene, a rare life-threatening infection requiring urgent surgical intervention), have occurred in patients with and without diabetes mellitus receiving SGLT2 inhibitors, including empagliflozin . Cases have required hospitalization . In patients with Fournier's gangrene, serious outcomes have included multiple surgeries and death. SYNJARDY and SYNJARDY XR are only indicated for use in patients with type 2 diabetes mellitus. Patients with a history of chronic or recurrent genitourinary infections are more likely to develop genitourinary infections when using SYNJARDY or SYNJARDY XR. Monitor patients for signs and symptoms of genitourinary infections and treat promptly, if indicated. Immediately evaluate patients presenting with pain or tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise, for necrotizing fasciitis. If suspected, discontinue SYNJARDY or SYNJARDY XR and promptly institute appropriate medical and/or surgical intervention

Hypoglycemia Insulin and insulin secretagogues are known to cause hypoglycemia. In adult patients, the risk of hypoglycemia may be increased when SYNJARDY or SYNJARDY XR is used in combination with insulin secretagogues (e.g., sulfonylurea) or insulin. In pediatric patients aged 10 years and older, the risk of hypoglycemia was higher with empagliflozin regardless of insulin use . The risk of hypoglycemia may be lowered by a reduction in the dose of sulfonylurea (or other concomitantly administered insulin secretagogues) or insulin. Inform patients using these concomitant medications and pediatric patients of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia

Lower Limb Amputation In some clinical studies with SGLT2 inhibitors an imbalance in the incidence of lower limb amputation has been observed. Across four empagliflozin outcome trials, lower limb amputation event rates were 4.3 and 5.0 events per 1,000 patient-years in the placebo group and the empagliflozin 10 mg or 25 mg dose group, respectively, with a HR of 1.05 (95% CI) (0.81, 1.36). In a long-term cardio-renal outcome trial with empagliflozin, in patients with chronic kidney disease, the occurrence of lower limb amputations was reported with event rates of 2.9, and 4.3 events per 1,000 patient-years in the placebo, and empagliflozin 10 mg treatment arms, respectively. Amputation of the toe and mid-foot were most frequent (21 out of 28 empagliflozin 10 mg treated patients with lower limb amputations), and some involving above and below the knee. Some patients had multiple amputations. Peripheral artery disease, and diabetic foot infection (including osteomyelitis), were the most common precipitating medical events leading to the need for an amputation. The risk of amputation was highest in patients with a baseline history of diabetic foot, peripheral artery disease (including previous amputation) or diabetes. Counsel patients about the importance of routine preventative foot care. Monitor patients receiving SYNJARDY or SYNJARDY XR for signs and symptoms of diabetic foot infection (including osteomyelitis), new pain or tenderness, sores or ulcers involving the lower limbs, and institute appropriate treatment

Hypersensitivity Reactions There have been postmarketing reports of serious hypersensitivity reactions (e.g., angioedema) in patients treated with empagliflozin. If a hypersensitivity reaction occurs, discontinue SYNJARDY or SYNJARDY XR; treat promptly per standard of care, and monitor until signs and symptoms resolve. SYNJARDY and SYNJARDY XR are contraindicated in patients with hypersensitivity to empagliflozin or any of the excipients in SYNJARDY or SYNJARDY XR

Vitamin B 12 Deficiency In metformin HCl clinical trials of 29-week duration, a decrease to subnormal levels of previously normal serum vitamin B 12 levels was observed in approximately 7% of metformin-treated patients. Such decrease, possibly due to interference with B 12 absorption from the B 12 -intrinsic factor complex, may be associated with anemia but appears to be rapidly reversible with discontinuation of metformin or vitamin B 12 supplementation. Certain individuals (those with inadequate vitamin B 12 or calcium intake or absorption) appear to be predisposed to developing subnormal vitamin B 12 levels. Measure hematologic parameters on an annual basis and vitamin B 12 at 2 to 3 year intervals in patients on SYNJARDY or SYNJARDY XR and manage any abnormalities .

See Table 4 for clinically relevant interactions with SYNJARDY or SYNJARDY XR. Table 4 Clinically Relevant Interactions with SYNJARDY or SYNJARDY XR Carbonic Anhydrase Inhibitors Clinical Impact Topiramate or other carbonic anhydrase inhibitors (e.g., zonisamide, acetazolamide or dichlorphenamide) frequently causes a decrease in serum bicarbonate and induce non-anion gap, hyperchloremic metabolic acidosis. Concomitant use of these drugs with SYNJARDY or SYNJARDY XR may increase the risk of lactic acidosis. Intervention Consider more frequent monitoring of these patients. Drugs that Reduce Metformin Clearance Clinical Impact Concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2] / multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) could increase systemic exposure to metformin and may increase the risk for lactic acidosis . Intervention Consider the benefits and risks of concomitant use. Alcohol Clinical Impact Alcohol is known to potentiate the effect of metformin on lactate metabolism. Intervention Warn patients against excessive alcohol intake while receiving SYNJARDY or SYNJARDY XR. Diuretics Clinical Impact Coadministration of empagliflozin with diuretics resulted in increased urine volume and frequency of voids, which might enhance the potential for volume depletion. Intervention Before initiating SYNJARDY or SYNJARDY XR, assess volume status and renal function. In patients with volume depletion, correct this condition before initiating SYNJARDY or SYNJARDY XR. Monitor for signs and symptoms of volume depletion, and renal function after initiating therapy. Insulin or Insulin Secretagogues Clinical Impact The risk of hypoglycemia is increased when SYNJARDY or SYNJARDY XR is used in combination with insulin secretagogues (e.g., sulfonylurea) or insulin. Intervention Coadministration of SYNJARDY or SYNJARDY XR with an insulin secretagogue (e.g., sulfonylurea) or insulin may require lower dosages of the insulin secretagogue or insulin to reduce the risk of hypoglycemia. Drugs Affecting Glycemic Control Clinical Impact Certain drugs tend to produce hyperglycemia and may lead to loss of glycemic control. These drugs include the thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid. Intervention When such drugs are administered to a patient receiving SYNJARDY or SYNJARDY XR, the patient should be closely observed to maintain adequate glycemic control. When such drugs are withdrawn from a patient receiving SYNJARDY or SYNJARDY XR, the patient should be observed closely for hypoglycemia. Lithium Clinical Impact Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations. Intervention Monitor serum lithium concentration more frequently during SYNJARDY or SYNJARDY XR initiation and dosage changes. Positive Urine Glucose Test Clinical Impact SGLT2 inhibitors increase urinary glucose excretion and will lead to positive urine glucose tests. Intervention Monitoring glycemic control with urine glucose tests is not recommended in patients taking SGLT2 inhibitors. Use alternative methods to monitor glycemic control. Interference with 1,5-anhydroglucitol (1,5-AG) Assay Clinical Impact Measurements of 1,5-AG are unreliable in assessing glycemic control in patients taking SGLT2 inhibitors. Intervention Monitoring glycemic control with 1,5-AG assay is not recommended. Use alternative methods to monitor glycemic control. Carbonic Anhydrase Inhibitors: May increase risk of lactic acidosis. Consider more frequent monitoring. Drugs that Reduce Metformin Clearance: May increase risk of lactic acidosis. Consider benefits and risks of concomitant use. See full prescribing information for additional drug interactions and information on interference of SYNJARDY or SYNJARDY XR with laboratory tests.
