⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

🚨 Boxed Warning ▾
WARNING: LACTIC ACIDOSIS Post-marketing 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/Liter), anion gap acidosis (without evidence of ketonuria or ketonemia), an increased lactate/pyruvate ratio; and metformin plasma levels generally >5 mcg/mL [see Warnings and Precautions (5.1) ] .
Risk factors for metformin-associated lactic acidosis include renal impairment, concomitant use of certain drugs (e.g., carbonic anhydrase inhibitors such as topiramate), age 65 years old or greater, having a radiological study with contrast, surgery and other procedures, hypoxic states (e.g., acute congestive heart failure), excessive alcohol intake, hepatic impairment, and mitochondrial diseases [see Warnings and Precautions (5.1) ] . Steps to reduce the risk of and manage metformin-associated lactic acidosis in these high risk groups are provided in the full prescribing information [see Dosage and Administration (2.2 , 2.3) , Contraindications (4) , Warnings and Precautions (5.1) , Drug Interactions (7) , and Use in Specific Populations (8.6 , 8.7) ] .
If metformin-associated lactic acidosis is suspected, immediately discontinue INVOKAMET or INVOKAMET XR and institute general supportive measures in a hospital setting. Prompt hemodialysis is recommended [see Warnings and Precautions (5.1) ] . WARNING: LACTIC ACIDOSIS See full prescribing information for complete boxed warning.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis : Consider ketone monitoring in patients at risk for ketoacidosis, as indicated. Assess for ketoacidosis regardless of presenting blood glucose levels and discontinue INVOKAMET or INVOKAMET XR if ketoacidosis is suspected. Monitor patients for resolution of ketoacidosis before restarting ( 5.2 ).
Lower Limb Amputation : Monitor patients for infection or ulcers of lower limb and institute appropriate treatment ( 5.3 ). Volume Depletion : May result in acute kidney injury. Before initiating, assess and correct volume status in patients with renal impairment, elderly patients, or patients on loop diuretics.
Monitor for signs and symptoms during therapy ( 5.4 ). 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 INVOKAMET or INVOKAMET XR, and promptly institute appropriate medical and/or surgical intervention ( 5.5 ).
Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues : Consider a lower dose of insulin or insulin secretagogue to reduce the risk of hypoglycemia when used in combination ( 5.6 ). Hypersensitivity Reactions : Discontinue and monitor until signs and symptoms resolve ( 5.7 ). Bone Fracture : Consider factors that contribute to fracture risk before initiating INVOKAMET or INVOKAMET XR ( 5.8 ).
Vitamin B 12 Deficiency : Metformin HCl may lower vitamin B 12 levels. Measure hematological parameters annually and vitamin B 12 at 2- to 3-year intervals and manage any abnormalities ( 5.9 ).
5.1Lactic Acidosis There have been post-marketing 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 INVOKAMET or INVOKAMET XR. In INVOKAMET or INVOKAMET 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/min 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 INVOKAMET or INVOKAMET 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 ren…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following important adverse reactions are also discussed elsewhere in the labeling: Lactic Acidosis [see Boxed Warning and Warnings and Precautions (5.1 , 5.4) ] Diabetic Ketoacidosis in Patients with Type 1 Diabetes and Other Ketoacidosis [see Warnings and Precautions (5.2) ] Lower Limb Amputation [see Warnings and Precautions (5.3) ] Volume Depletion [see Warnings and Precautions (5.4) ] Genitourinary Infections, including Urosepsis, Pyelonephritis, Necrotizing Fasciitis of the Perineum (Fournier's Gangrene), and Genital Mycotic Infections [see Warnings and Precautions (5.5) ] Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues [see Warnings and Precautions (5.6) ] Hypersensitivity Reactions [see Warnings and Precautions (5.7) ] Bone Fracture [see Warnings and Precautions (5.8) ] Vitamin B 12 Deficiency [see Warnings and Precautions (5.9) ] Most common adverse reactions associated with canagliflozin (5% or greater incidence): female genital mycotic infections, urinary tract infection, and increased urination ( 6.1 ).
Most common adverse reactions associated with metformin HCl (5% or greater incidence) are diarrhea, nausea, vomiting, flatulence, asthenia, indigestion, abdominal discomfort, and headache ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Janssen Pharmaceuticals, Inc. at 1-800-526-7736 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Canagliflozin has been evaluated in clinical trials in adults and pediatric patients aged 10 years and older with type 2 diabetes mellitus. Additionally, canagliflozin has been studied in clinical trials in adult patients with type 2 diabetes mellitus who also have heart failure or chronic kidney disease.
The overall safety profile of canagliflozin was consistent across the studied indications. Clinical Trials in Adults with Type 2 Diabetes Mellitus Pool of Placebo-Controlled Trials for Glycemic Control Canagliflozin The data in Table 3 are derived from four 26-week placebo-controlled trials where canagliflozin was used as monotherapy in one trial and as add-on therapy in three trials. These data reflect exposure of 1,667 adult patients to canagliflozin and a mean duration of exposure to canagliflozin of 24 weeks with 1,275 patients exposed to a combination of canagliflozin and metformin HCl.
Patients received canagliflozin 100 mg (N=833), canagliflozin 300 mg (N=834) or placebo (N=646) once daily. The mean daily dose of metformin HCl was 2,138 mg (SD 337.3) for the 1,275 patients in the three placebo-controlled metformin HCl add-on trials. The mean age of the population was 56 years and 2% were older than 75 years of age.
Fifty percent (50%) of the population was male and 72% were White, 12% were Asian, and 5% were Black or African American. At baseline the population had diabetes for an average of 7.3 years, had a mean HbA 1C of 8.0% and 20% had established microvascular complications of diabetes. Baseline renal function was normal or mildly impaired (mean eGFR 88 mL/min/1.73 m 2 ).
Table 3 shows common adverse reactions associated with the use of canagliflozin. These adverse reactions were not present at baseline, occurred more commonly on canagliflozin than on placebo, and occurred in at least 2% of patients treated with either canagliflozin 100 mg or canagliflozin 300 mg. Table 3: Adverse Reactions from Pool of Four 26-Week Placebo-Controlled Trials Reported in ≥ 2% of Canagliflozin-Treated Adult Patients The four placebo-controlled trials included one monotherapy trial and three add-on combination trials with metformin HCl, metformin HCl and sulfonylurea, or metformin HCl and pioglitazone.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Table 8: Clinically Significant Drug Interactions with INVOKAMET or INVOKAMET XR Carbonic Anhydrase Inhibitors Clinical Impact: Carbonic anhydrase inhibitors frequently cause a decrease in serum bicarbonate and induce non-anion gap, hyperchloremic metabolic acidosis. Concomitant use of these drugs with INVOKAMET or INVOKAMET XR may increase the risk for lactic acidosis. Intervention: Consider more frequent monitoring of these patients.
Examples: Topiramate or other carbonic anhydrase inhibitors (e.g., zonisamide, acetazolamide or dichlorphenamide) 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) could increase systemic exposure to metformin and may increase the risk for lactic acidosis [see Clinical Pharmacology (12.3) ].
Intervention: Consider the benefits and risks of concomitant use. Examples: Ranolazine, vandetanib, dolutegravir, and cimetidine Alcohol Clinical Impact: Alcohol is known to potentiate the effect of metformin HCl on lactate metabolism. Intervention: Warn patients against excessive alcohol intake while receiving INVOKAMET or INVOKAMET XR.
UGT Enzyme Inducers Clinical Impact: UGT enzyme inducers decrease canagliflozin exposure which may reduce the effectiveness of INVOKAMET or INVOKAMET XR. Intervention: For patients with eGFR 60 mL/min/1.73 m 2 or greater, if an inducer of UGTs is co-administered with INVOKAMET or INVOKAMET XR, increase the total daily dose of canagliflozin to 200 mg in patients currently tolerating INVOKAMET or INVOKAMET XR with a total daily dose of canagliflozin 100 mg. The total daily dose of canagliflozin may be increased to 300 mg in patients currently tolerating canagliflozin 200 mg and who require additional glycemic control.
For patients with eGFR less than 60 mL/min/1.73 m 2 , if an inducer of UGTs is co-administered with INVOKAMET or INVOKAMET XR, increase the total daily dose of canagliflozin to 200 mg in patients currently tolerating canagliflozin 100 mg [see Dosage and Administration (2.4) and Clinical Pharmacology (12.3) ] . Examples: Rifampin, phenytoin, phenobarbital, ritonavir Insulin or Insulin Secretagogues Clinical Impact: The risk of hypoglycemia is increased when INVOKAMET or INVOKAMET XR is used concomitantly with insulin secretagogues (e.g., sulfonylurea) or insulin.
Intervention: Concomitant use may require a lower dosage 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. Intervention: When such drugs are administered to a patient receiving INVOKAMET or INVOKAMET XR, monitor for loss of blood glucose control.
When such drugs are withdrawn from a patient receiving INVOKAMET or INVOKAMET XR, monitor for hypoglycemia. Examples: Thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blockers, and isoniazid. Digoxin Clinical Impact: Canagliflozin increases digoxin exposure [see Clinical Pharmacology (12.3) ] .
Intervention: Monitor patients taking INVOKAMET or INVOKAMET XR with concomitant digoxin for a need to adjust the dosage of digoxin. Lithium Clinical Impact: Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations. Intervention: Monitor serum lithium concentration more frequently during INVOKAMET or INVOKAMET XR initiation and dosage changes.
Drug/Laboratory Test Interference Positive Urine Glucose Test Clinical Impact: SGLT2 inhibitors increase urinary glucose excretion which will lead to positive urine glucose tests. Intervention: Monitoring glycemic control with urine glucose tests is not recommended in p…
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy : Advise females of the potential risk to a fetus especially during the second and third trimesters ( 8.1 ). Lactation : Not recommended when breastfeeding ( 8.2 ). Females and Males of Reproductive Potential : Advise premenopausal females of the potential for an unintended pregnancy ( 8.3 ).
Geriatrics : Higher incidence of adverse reactions related to reduced intravascular volume. Assess renal function more frequently ( 8.5 ). Renal Impairment : Higher incidence of adverse reactions related to hypotension and renal function ( 8.6 ).
Hepatic Impairment : Avoid use in patients with hepatic impairment ( 8.7 ).
8.1Pregnancy Risk Summary Based on juvenile animal data showing adverse renal effects from canagliflozin, INVOKAMET or INVOKAMET XR is not recommended during the second and third trimesters of pregnancy. Limited data with INVOKAMET, INVOKAMET XR or canagliflozin in pregnant women are not sufficient to determine a drug-associated risk for major birth defects or miscarriage. Published studies with metformin HCl use during pregnancy have not reported a clear association with metformin HCl and major birth defect or miscarriage risk [see Data ].
There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy [see Clinical Considerations ]. In juvenile animal studies, adverse renal pelvic and tubule dilatations that were not reversible were observed in rats when canagliflozin was administered during a period of renal development corresponding to the late second and third trimesters of human pregnancy, at an exposure 0.5-times the 300 mg clinical dose, based on AUC. No adverse developmental effects were observed when metformin HCl was administered to pregnant Sprague Dawley rats and rabbits during the period of organogenesis at doses up to 2- and 6-times, respectively, a 2,000 mg clinical dose, based on body surface area [see Data ] .
The estimated background risk of major birth defects is 6–10% in women with pre-gestational diabetes with a HbA 1C >7 and has been reported to be as high as 20–25% in women with a HbA 1C >10. The estimated background risk of miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively.
Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity. Data Human Data Published data from post-marketing studies have not reported a clear association with metformin HCl and major birth defects, miscarriage, or adverse maternal or fetal outcomes when metformin HCl was used during pregnancy.
However, these studies cannot definitely establish the absence of any metformin-associated risk because of methodological limitations, including small sample size and inconsistent comparator groups. Animal Data Canagliflozin Canagliflozin dosed directly to juvenile rats from postnatal day (PND) 21 until PND 90 at doses of 4, 20, 65, or 100 mg/kg increased kidney weights and dose dependently increased the incidence and severity of renal pelvic and tubular dilatation at all doses tested. Exposure at the lowest dose was greater than or equal to 0.5-times the 300 mg clinical dose, based on AUC.
These outcomes occurred with drug exposure during periods of renal development in rats that correspond to the late second and third trimester of human renal development. The renal pelvic dilatations observed in juvenile animals did not fully reverse within a 1-month recovery period. In embryo-fetal development studies in rats and rabbits, canagliflozin was administered for intervals coinciding…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of INVOKAMET and INVOKAMET XR as an adjunct to diet and exercise to improve glycemic control in type 2 diabetes mellitus have been established in pediatric patients aged 10 years and older. Use of INVOKAMET and INVOKAMET XR for this indication is supported by evidence from a 52-week double-blind, placebo-controlled trial of canagliflozin in 171 pediatric patients aged 10 to 17 years with type 2 diabetes mellitus and in a pediatric pharmacokinetic study [see Clinical Pharmacology (12.3) and Clinical Studies (14.2) ] .
The safety profile of pediatric patients treated with canagliflozin was similar to that observed in adults with type 2 diabetes mellitus. The use of INVOKAMET and INVOKAMET XR for this indication is also supported by evidence from adequate and well-controlled trials of metformin HCl immediate-release tablets in adults with additional data from a controlled clinical trial using metformin HCl immediate-release tablets in pediatric patients 10 to 16 years old with type 2 diabetes mellitus [see Clinical Studies (14.1 , 14.2) ].
In the clinical trial with pediatric patients receiving metformin HCl immediate-release tablets, adverse reactions with metformin HCl immediate-release tablets were similar to those described in adults [see Adverse Reactions (6.1) ]. The safety and effectiveness of INVOKAMET or INVOKAMET XR for glycemic control in patients with type 2 diabetes mellitus have not been established in pediatric patients under 10 years of age. The safety and effectiveness of INVOKAMET or INVOKAMET XR have not been established in pediatric patients to reduce the risk of: major adverse cardiovascular events (cardiovascular death, nonfatal myocardial infarction and nonfatal stroke) in patients with type 2 diabetes mellitus and established cardiovascular disease (CVD). end-stage kidney disease (ESKD), doubling of serum creatinine, cardiovascular (CV) death, and hospitalization for heart failure in patients with type 2 diabetes mellitus and diabetic nephropathy with albuminuria greater than 300 mg/day.
🧓 Geriatric Use ▾
8.5Geriatric Use INVOKAMET and INVOKAMET XR Because renal function abnormalities can occur after initiating canagliflozin, metformin is substantially excreted by the kidney, and aging can be associated with reduced renal function, monitor renal function more frequently after initiating INVOKAMET or INVOKAMET XR in the elderly and then adjust dose based on renal function [see Dosage and Administration (2.3) and Warnings and Precautions (5.1 , 5.4) ] . Canagliflozin In 13 clinical trials of canagliflozin, 2,294 patients 65 years and older, and 351 patients 75 years and older were exposed to canagliflozin.
Of these patients, 1,534 patients 65 years and older and 196 patients 75 years and older were exposed to the combination of canagliflozin and metformin HCl [see Clinical Studies (14.1) ] . Patients 65 years and older had a higher incidence of adverse reactions related to reduced intravascular volume with canagliflozin (such as hypotension, postural dizziness, orthostatic hypotension, syncope, and dehydration), particularly with the 300 mg daily dose, compared to younger patients; a more prominent increase in the incidence was seen in patients who were 75 years and older [see Dosage and Administration (2.1) and Adverse Reactions (6.1) ].
Smaller reductions in HbA 1C with canagliflozin relative to placebo were seen in older (65 years and older; -0.61% with canagliflozin 100 mg and -0.74% with canagliflozin 300 mg relative to placebo) compared to younger patients (-0.72% with canagliflozin 100 mg and -0.87% with canagliflozin 300 mg relative to placebo). Metformin HCl Controlled clinical trials of metformin HCl did not include sufficient numbers of elderly patients to determine whether they respond differently from younger patients, although other reported clinical experience has not identified differences in responses between the elderly and younger patients.
The initial and maintenance dosing of metformin HCl should be conservative in patients with advanced age due to the potential for decreased renal function in this population. Any dose adjustment should be based on a careful assessment of renal function [see Contraindications (4) , Warnings and Precautions (5.4) , and Clinical Pharmacology (12.3) ] .
🆘 Overdosage ▾
10 OVERDOSAGE Overdose of metformin HCl has occurred, including ingestion of amounts greater than 50 grams. Hypoglycemia was reported in approximately 10% of cases, but no causal association with metformin HCl use has been established. Lactic acidosis has been reported in approximately 32% of metformin HCl overdose cases [see Warnings and Precautions (5.1) ] .
In the event of an overdose with INVOKAMET or INVOKAMET XR, contact the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations. Employ the usual supportive measures (e.g., remove unabsorbed material from the gastrointestinal tract, employ clinical monitoring, and institute supportive treatment) as dictated by the patient's clinical status. Canagliflozin was negligibly removed during a 4-hour hemodialysis session.
Canagliflozin is not expected to be dialyzable by peritoneal dialysis. Metformin is dialyzable with a clearance of up to 170 mL/min under good hemodynamic conditions. Therefore, hemodialysis may be useful partly for removal of accumulated metformin from patients in whom INVOKAMET or INVOKAMET XR overdosage is suspected.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Canagliflozin SGLT2, expressed in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Canagliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose and lowers the renal threshold for glucose (RT G ), and thereby increases urinary glucose excretion (UGE).
Canagliflozin increases the delivery of sodium to the distal tubule by blocking SGLT2-dependent glucose and sodium reabsorption. This is believed to increase tubuloglomerular feedback and reduce intraglomerular pressure. Metformin HCl Metformin HCl is an antihyperglycemic agent which improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose.
Metformin HCl decreases hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization. With metformin therapy, insulin secretion remains unchanged while fasting insulin levels and day-long plasma insulin response may decrease.
12.2Pharmacodynamics Canagliflozin Following single and multiple oral doses of canagliflozin in adult patients with type 2 diabetes, dose-dependent decreases in RT G and increases in urinary glucose excretion were observed. From a starting RT G value of approximately 240 mg/dL, canagliflozin at 100 mg and 300 mg once daily suppressed RT G throughout the 24-hour period. Data from single oral doses of canagliflozin in healthy volunteers indicate that, on average, the elevation in urinary glucose excretion approaches baseline by about 3 days for doses up to 300 mg once daily.
Maximal suppression of mean RT G over the 24-hour period was seen with the 300 mg daily dose to approximately 70 to 90 mg/dL in patients with type 2 diabetes in Phase 1 trials. The reductions in RT G led to increases in mean UGE of approximately 100 g/day in patients with type 2 diabetes treated with either 100 mg or 300 mg of canagliflozin. The 24-h mean RT G at steady state was similar following once daily and twice daily dosing regimens at the same total daily dose of 100 mg or 300 mg.
In patients with type 2 diabetes given 100 to 300 mg once daily over a 16-day dosing period, reductions in RT G and increases in urinary glucose excretion were observed over the dosing period. In this trial, plasma glucose declined in a dose-dependent fashion within the first day of dosing. Cardiac Electrophysiology In a randomized, double-blind, placebo-controlled, active-comparator, 4-way crossover trial, 60 healthy adult subjects were administered a single oral dose of canagliflozin 300 mg, canagliflozin 1,200 mg (4 times the maximum recommended dose), moxifloxacin, and placebo.
No meaningful changes in QTc interval were observed with either the recommended dose of 300 mg or the 1,200 mg dose.
12.3Pharmacokinetics INVOKAMET Administration of INVOKAMET 150 mg/1,000 mg fixed-dose combination with food resulted in no change in overall exposure of canagliflozin. There was no change in metformin AUC; however, the mean peak plasma concentration of metformin was decreased by 16% when administered with food. A delayed time to peak plasma concentration was observed for both components (a delay of 2 hours for canagliflozin and 1 hour for metformin) under fed conditions.
These changes are not likely to be clinically meaningful. INVOKAMET XR After administration of INVOKAMET XR tablets with a high-fat breakfast, the peak (C max ) and total (AUC) exposure of canagliflozin were not altered relative to dosing in the fasted state. However, the AUC of metformin increased by approximately 61% and C max increased by approximately 13%.
Canagliflozin The pharmacokinetics of canagliflozin is essentially similar in healthy subjects and patients with type 2 diabetes. Following single-dose oral administration of 100 mg and 300 mg of canagliflozin, peak plasma…

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide) . Lactic Acidosis Explain the risks of lactic acidosis, its symptoms, and conditions that predispose to its development, as noted in Warnings and Precautions (5.1) . Advise patients to discontinue INVOKAMET or INVOKAMET XR immediately and to promptly notify their health care provider if unexplained hyperventilation, myalgias, malaise, unusual somnolence or other nonspecific symptoms occur.
Once a patient is stabilized on INVOKAMET or INVOKAMET XR, gastrointestinal symptoms, which are common during initiation of metformin HCl, are unlikely to recur. Later occurrence of gastrointestinal symptoms could be due to lactic acidosis or other serious disease. Counsel patients against excessive alcohol intake while receiving INVOKAMET or INVOKAMET XR.
Inform patients about importance of regular testing of renal function and hematological parameters while receiving INVOKAMET or INVOKAMET XR. Instruct patients to inform their doctor that they are taking INVOKAMET or INVOKAMET XR prior to any surgical or radiological procedure, as temporary discontinuation of INVOKAMET or INVOKAMET XR may be required until renal function has been confirmed to be normal [see Warnings and Precautions (5.1) ] . Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis Inform patients that INVOKAMET or INVOKAMET XR can cause potentially fatal ketoacidosis and that type 2 diabetes mellitus and pancreatic disorders (e.g., history of pancreatitis or pancreatic surgery) are risk factors.
Educate all patients on precipitating factors (such as insulin dose reduction or missed doses, infection, reduced caloric intake, ketogenic diet, surgery, dehydration, and alcohol abuse) and symptoms of ketoacidosis (including nausea, vomiting, abdominal pain, tiredness, and labored breathing). Inform patients that blood glucose may be normal even in the presence of ketoacidosis. Advise patients that they may be asked to monitor ketones.
If symptoms of ketoacidosis occur, instruct patients to discontinue INVOKAMET or INVOKAMET XR and seek medical attention immediately [see Warnings and Precautions (5.2) ] . Lower Limb Amputation Counsel patients about the importance of routine preventative foot care. Instruct patients to monitor for new pain or tenderness, sores or ulcers, or infections involving the leg or foot and to seek medical advice immediately if such signs or symptoms develop [see Warnings and Precautions (5.3) ] .
Volume Depletion Inform patients that symptomatic hypotension may occur with INVOKAMET or INVOKAMET XR and advise them to contact their doctor if they experience such symptoms [see Warnings and Precautions (5.4) ] .

INVOKAMET and INVOKAMET XR can cause serious side effects, including: Lactic Acidosis. Metformin, one of the medicines in INVOKAMET and INVOKAMET XR, can cause a rare but serious condition called lactic acidosis (a build-up of lactic acid in the blood) that can cause death. Lactic acidosis is a medical emergency and must be treated in the hospital.
Stop taking INVOKAMET or INVOKAMET XR and call your healthcare provider right away if you have any of the following symptoms of lactic acidosis: feel cold in your hands or feet feel very weak or tired have trouble breathing have stomach pains, nausea, or vomiting have a slow or irregular heartbeat have unusual (not normal) muscle pain have unusual sleepiness or sleep longer than usual feel dizzy or lightheaded Most people who have had lactic acidosis had other conditions that, in combination with metformin use, led to the lactic acidosis.
Tell your healthcare provider if you have any of the following, because you have a higher chance for getting lactic acidosis with INVOKAMET or INVOKAMET XR if you: have severe kidney problems or your kidneys are affected by certain x-ray tests that use injectable dye. have liver problems. drink alcohol very often or drink a lot of alcohol in short-term "binge" drinking. get dehydrated (lose a large amount of body fluids). This can happen if you are sick with a fever, vomiting, or diarrhea. Dehydration can also happen when you sweat a lot with activity or exercise and do not drink enough fluids. have surgery. have new or worsening symptoms of congestive heart failure such as shortness of breath or increased fluid or swelling of the legs. have a heart attack, severe infection, or stroke. are 65 years of age or older. have a genetically inherited disease affecting mitochondria (the energy-producing parts within cells) such as mitochondrial encephalomyopathy with lactic acidosis, and stroke-like episodes (MELAS) syndrome and maternally inherited diabetes and deafness (MIDD).
The best way to keep from having a problem with lactic acidosis from metformin is to tell your healthcare provider if you have any of the problems in the list above. Your healthcare provider will decide to stop your INVOKAMET or INVOKAMET XR for a while if you have any of these things.
