Rosiglitazone is a thiazolidinedione antidiabetic agent that lowers blood glucose by improving target cell response to insulin, without increasing pancreatic insulin secretion. It has a mechanism of action that is dependent on the presence of insulin for activity. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity (increases peripheral glucose uptake and utilization).
Special Populations: Renal Function Impairment
Plasma and blood half-life of metformin is prolonged and the renal Cl is decreased in proportion to the decrease in CrCl.
Special Populations: Hepatic Function Impairment
Clearance of rosiglitazone was significantly lower in patients with moderate to severe liver disease and Cmax and AUC0-∞ were increased 2- and 3-fold, respectively.
Use: Labeled Indications
Diabetes mellitus, type 2: Adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.
Hypersensitivity to rosiglitazone or any component of the formulation; initiation in patients with established NYHA class III or IV heart failure; severe renal impairment (eGFR below 30 mL/minute/1.73 m2); acute or chronic metabolic acidosis, including diabetic ketoacidosis, with or without coma.
Canadian labeling: Additional contraindications (not in US labeling): Hypersensitivity to rosiglitazone, metformin, or any component of the formulation; any stage of heart failure (eg, NYHA class I, II, III, or IV); history of lactic acidosis, regardless of precipitating factors; history of ketoacidosis with or without coma; serious hepatic impairment; type I diabetes; cardiovascular collapse and disease states associated with hypoxemia (eg, cardiorespiratory insufficiency) which are often associated with hyperlactacidemia; unknown renal function; serum creatinine levels above the upper limit of normal range; pregnancy; breast-feeding; use during stress conditions (eg, severe infection, trauma, surgery) and the recovery phase thereafter; excessive alcohol intake (acute or chronic); severe dehydration
Diabetes mellitus, type 2: Oral:
Patients inadequately controlled on diet and exercise alone: Rosiglitazone 2 mg/metformin 500 mg once or twice daily (consider twice daily administration if HbA1c >11% or fasting plasma glucose (FPG) >270 mg/dL.
Patients inadequately controlled on metformin alone: Rosiglitazone 4 mg/day plus current daily dose of metformin administered in 2 divided doses.
Patients inadequately controlled on rosiglitazone alone: Metformin 1,000 mg/day plus current daily dose of rosiglitazone administered in 2 divided doses.
Patients switching from combination therapy of rosiglitazone and metformin as separate tablets: Use current dose.
Patients inadequately controlled on diet and exercise alone: If not adequately controlled after 4 weeks, the dose may be increased in increments of rosiglitazone 2 mg/metformin 500 mg per day.
Patients switching from rosiglitazone or metformin alone or combination therapy: May titrate in increments of rosiglitazone 4 mg and/or metformin 500 mg per day; allow adequate time to assess therapeutic response prior to each titration (as separate agents, rosiglitazone and metformin are titrated at intervals of 8 to 12 weeks and 1 to 2 weeks respectively).
Maximum dose: Rosiglitazone 8 mg/metformin 2,000 mg per day in 2 divided doses.
Refer to adult dosing. The initial and maintenance dosing should be conservative, due to the potential for decreased renal function (monitor).
Dosing: Renal Impairment
eGFR >45mL/minute/1.73 m2: No dosage adjustment necessary.
eGFR 30 to 45 mL/minute/1.73 m2: Use is not recommended for initiation of therapy; if eGFR falls to <45 mL/minute/1.73 m2 during therapy, consider benefits/risks of continuing therapy.
eGFR <30 mL/minute/1.73 m2: Use is contraindicated.
Dosing: Hepatic Impairment
The manufacturer recommends to avoid metformin since liver disease is considered a risk factor for the development of lactic acidosis during metformin therapy. However, continued use of metformin in diabetics with liver dysfunction, including cirrhosis, has been used successfully and may be associated with a survival benefit in carefully selected patients; use cautiously in patients at risk for lactic acidosis (eg, renal impairment, alcohol use) (Brackett 2010; Zhang 2014). Do not initiate rosiglitazone therapy with active liver disease or ALT >2.5 times the upper limit of normal.
Oral: Administer with meals, generally in divided doses.
Should be taken with meals. Avoid ethanol. Dietary modification based on ADA recommendations is a part of therapy. Monitor for signs and symptoms of vitamin B12 and/or folic acid deficiency; supplementation may be required.

Concerns related to adverse effects:
• Edema: Dose-related edema may occur. Use with caution in patients with edema; may increase plasma volume and/or cause fluid retention. Monitor for signs/symptoms of heart failure.
• Fractures: Increased incidence of bone fractures in females treated with rosiglitazone was observed during analysis of long-term trial; majority of fractures occurred in the upper arm, hand and foot (differing from the hip or spine fractures usually associated with postmenopausal osteoporosis). Consider risk of fracture prior to initiation and during use.
• Heart failure/cardiac effects: [US Boxed Warning]: Thiazolidinediones, including rosiglitazone, may cause or exacerbate congestive heart failure (HF); closely monitor for signs and symptoms of congestive HF (eg, rapid weight gain, dyspnea, edema), particularly after initiation or dose increases; if HF develops, treat accordingly and consider dose reduction or discontinuation. Not recommended for use in any patient with symptomatic HF. Initiation of therapy is contraindicated in patients with NYHA class III or IV HF. Rosiglitazone may be associated with an increased risk of angina and MI and a higher frequency of cardiovascular events has also been noted in patients with NYHA class I or II HF treated with rosiglitazone. Metformin may be used in patients with stable HF; avoid use in unstable or hospitalized patients with HF (ADA 2018d). 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). Use with caution in patients at risk for cardiovascular events and monitor closely. Discontinue if any deterioration in cardiac status occurs.
• Hematologic effects: Rosiglitazone may decrease hemoglobin, hematocrit, and/or WBC count (slight); effects may be related to increased plasma volume and/or dose-related. Changes in hemoglobin and hematocrit generally occurred during the first 3 months after initiation of rosiglitazone therapy and after dose increases. Use rosiglitazone with caution in patients with anemia or depressed leukocyte counts (may reduce hemoglobin, hematocrit, and/or WBC).
• Hypoglycemia: The risk of hypoglycemia is increased when rosiglitazone is combined with other hypoglycemic agents; dosage adjustment of concomitant hypoglycemic agents may be necessary.
• 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, 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 metformin in patients with conditions associated with dehydration, sepsis, or hypoxemia. The risk of accumulation and lactic acidosis increases with the degree of impairment of renal function.
• Macular edema: Has been reported with thiazolidinedione use, including rosiglitazone; some patients with macular edema presented with blurred vision or decreased visual acuity, and most had peripheral edema at time of diagnosis. In addition to regular ophthalmic exams, diabetic patients with visual symptoms should receive prompt ophthalmic evaluation. Improvement in macular edema may occur with discontinuation of rosiglitazone therapy.
• Weight gain: Dose-related weight gain has been observed with rosiglitazone; mechanism is unknown but likely is associated with fluid retention and fat accumulation.
• 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 2018c).
• Hepatic impairment: The manufacturer recommends to generally avoid use of metformin 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). Use rosiglitazone with caution in patients with elevated transaminases (AST or ALT); do not initiate in patients with active liver disease of ALT >2.5 times the upper limit of normal (ULN) at baseline; evaluate patients with ALT ≤2.5 times ULN at baseline or during therapy for cause of enzyme elevation. During therapy, if ALT >3 times ULN, reevaluate levels promptly and discontinue rosiglitazone if elevation persists or if jaundice occurs at any time during use. Idiosyncratic hepatotoxicity has been reported with another thiazolidinedione agent (troglitazone); avoid use in patients who previously experienced jaundice during troglitazone therapy.
• Ischemic heart disease: Do not initiate rosiglitazone in patients with stable ischemic heart disease due to an increased risk of cardiovascular complications (Fihn 2012).
• 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 is contraindicated in patients with eGFR <30 mL/minute/1.73 m2. Assess benefits/risks of metformin use in patients with eGFR 30 to 45 mL/minute/1.73 m2; if used, dosage reduction is recommended (ADA [Lipska 2011]; Inzucchi 2014). 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.
• Stress-related states: It may be necessary to discontinue metformin and administer insulin if the patient is exposed to stress (fever, trauma, infection, surgery).
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Elderly: Use with caution; risk of metformin associated lactic acidosis increases with age.
• Appropriate use: Not for use in patients with diabetic ketoacidosis (DKA) or patients with type 1 diabetes mellitus.
• Ethanol use: Instruct patients to avoid excessive acute or chronic ethanol use; ethanol may potentiate metformin's effect on lactate metabolism.
• Iodinated contrast: 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 (DSME) is essential to maximize the effectiveness of therapy.
• Surgical procedures: Metformin should be withheld the day of surgery (all other oral hypoglycemic agents should be withheld the morning of surgery or procedure) (ADA 2018e). Restart only after normal oral intake resumed and normal renal function is verified.
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 2018a]); serum glucose; CBC; vitamin B12 serum concentrations periodically with long-term therapy; folate (if megaloblastic anemia is suspected)
eGFR should be performed prior to initiation of therapy 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]); liver enzymes (prior to initiation of therapy, then periodically thereafter). Evaluate patients with ALT ≤2.5 times ULN at baseline or during therapy for cause of enzyme elevation. Patients with an elevation in ALT >3 times ULN should be rechecked as soon as possible. If the ALT levels remain >3 times ULN, therapy with rosiglitazone should be discontinued.
Blood pressure; signs and symptoms of fluid retention or heart failure; weight gain; ophthalmic exams (at least every 1 to 2 years, or more frequently if symptoms dictate) (ADA 2018g); fractures/fracture risk
Pregnancy Risk Factor
Metformin crosses the placenta (ADA 2018f). Animal reproduction studies were not conducted with this combination. Refer to individual agents.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience nausea, vomiting, diarrhea, flatulence, headache, rhinitis, pharyngitis, or joint pain. Have patient report immediately to prescriber signs of heart problems (cough or shortness of breath that is new or worse, swelling of the ankles or legs, abnormal heartbeat, weight gain of more than five pounds in 24 hours, dizziness, or passing out), signs of too much lactic acid in the blood (lactic acidosis; fast breathing, fast heartbeat, abnormal heartbeat, vomiting, drowsiness, shortness of breath, feeling very tired or weak, severe dizziness, feeling cold, or muscle pain or cramps), signs of liver problems (dark urine, feeling tired, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or yellow skin or eyes), bone pain, vision changes, loss of strength and energy, dysphagia, tachycardia, signs of low blood sugar (dizziness, headache, fatigue, feeling weak, shaking, a fast heartbeat, confusion, hunger, or sweating), or signs of a heart attack (angina; pain in arms, back, neck, jaw, or stomach; shortness of breath; cold sweats; severe dizziness; passing out; severe nausea or vomiting) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
