The following dosing information is available for METFORMIN HCL ER (metformin hcl):
For the management of type 2 diabetes mellitus in adults, the usual initial dosage of metformin hydrochloride as immediate-release tablets or immediate-release oral solution is 500 mg twice daily or 850 mg once daily with meals. Alternatively, an initial metformin hydrochloride dosage of 500 mg once daily has been suggested by some experts. Some manufacturers state that in general, clinically important responses are not observed at metformin hydrochloride dosages of less than 1.5
g daily.
When metformin hydrochloride is administered as an extended-release tablet preparation in adults, some manufacturers recommend an initial dosage of 500 mg once daily with the evening meal. The manufacturer of a certain extended-release tablet preparation (Fortamet(R)) recommends an initial dosage of 1 g once daily with the evening meal, although the manufacturer states that 500 mg once daily may be used when clinically appropriate. The recommended initial dosage of another extended-release preparation of metformin hydrochloride (Glumetza(R)) is 1 g once daily with the evening meal.
Subsequent dosage of metformin hydrochloride should be adjusted according to the patient's therapeutic response, using the lowest possible effective dosage. (See Dosage: Dosage Titration, under Dosage and Administration.)
Although satisfactory control of blood glucose concentrations may be achieved within a few days after dosage adjustment, the full effects of the drug may not be observed for up to 2 weeks.
Initial dosages of metformin hydrochloride in geriatric patients should be conservative (initiated at the low end of the dosage range) and should be titrated carefully; limited data suggest reducing dosage by approximately 33% in geriatric patients.
For the management of type 2 diabetes mellitus in children or adolescents 10-16 years of age, the usual initial dosage of metformin hydrochloride as immediate-release tablets or the immediate-release oral solution is 500 mg twice daily given in the morning and evening with meals. Safety and efficacy of Fortamet(R) and certain other extended-release tablet preparations of metformin hydrochloride have not been established in patients younger than 17 years of age; refer to labeling of specific preparations for details. Safety and efficacy of Glumetza(R), another extended-release tablet preparation, have not been established in patients younger than 18 years of age.
In adults receiving an initial metformin hydrochloride dosage of 500 mg twice daily as immediate-release tablets or the immediate-release oral solution, daily dosage may be increased by 500 mg at weekly intervals until the desired fasting blood glucose concentration is achieved or a dosage of 2.55 g daily is reached. In adults receiving an initial dosage of 500 mg of metformin hydrochloride once or twice daily (with breakfast and/or dinner), some experts recommend increasing the dosage to 850 mg or 1 g twice daily after 5-7 days if additional glycemic control is needed and the drug is well tolerated (e.g., no adverse GI effects).
If adverse GI effects appear during dosage titration of metformin hydrochloride, some experts suggest that dosage be decreased to the previous lower dosage, and further dosage increments attempted at a later time. In adults receiving an initial metformin hydrochloride dosage of 850 mg daily as immediate-release tablets or the immediate-release oral solution, daily dosage may be increased by 850 mg every other week (i.e., every 2 weeks) until the desired fasting blood glucose concentration is achieved or a total dosage of 2.55 g daily is reached.
For patients requiring additional glycemic control with metformin hydrochloride, a maximum daily dosage of 2.55 g as immediate-release tablets or the immediate-release oral solution may be used.
In adults (17-18 years of age or older) receiving Glumetza(R) or certain other extended-release metformin hydrochloride preparations, daily dosage may be increased by 500 mg at weekly intervals until the desired glycemic response is achieved or a maximum dosage of 2 g daily is reached. If glycemic control is not achieved with extended-release metformin hydrochloride tablets (e.g., Glumetza(R)) at a dosage of 2 g once daily, a dosage of 1 g twice daily should be considered. If a dosage exceeding 2 g daily is needed in patients receiving certain other extended-release metformin hydrochloride preparations, the manufacturers suggest that therapy be switched to immediate-release metformin hydrochloride tablets and dosage titrated up to a maximum dosage of 2.55
g daily in divided doses. Conversely, therapy with extended-release tablets may be substituted for immediate-release tablets at the same total daily dosage of immediate-release tablets, up to a dosage of 2 g once daily.
With another extended-release metformin hydrochloride preparation (Fortamet(R)), daily dosage may be increased by 500 mg at weekly intervals up to a maximum of 2.5 g once daily with the evening meal. In patients transferring from immediate-release tablets to an extended-release preparation, glycemic control should be closely monitored and dosage adjustments made accordingly.
Dosage in adults generally should not exceed 2.55 g daily when given as metformin hydrochloride immediate-release tablets or immediate-release oral solution, 2.5 g daily when given as certain extended-release tablets (e.g., Fortamet(R)), or 2 g daily when given as certain other extended-release tablet preparations.
Metformin hydrochloride dosages of up to 3 g daily have been associated with modestly greater effectiveness than 1.7 g daily. However, adverse GI effects may limit the maximum dosage that can be tolerated.
(Consult the manufacturer's labeling for product-specific details.) Dosages exceeding 2 g of metformin hydrochloride daily as immediate-release tablets or the immediate-release oral solution may be better tolerated if given in 3 divided doses daily with meals.
Metformin should be used with caution in geriatric patients since aging is associated with reduced renal function, and accumulation of the drug resulting in lactic acidosis may occur in patients with renal impairment. In addition, renal function should be monitored periodically in geriatric patients to determine the appropriate dosage of metformin hydrochloride. Any dosage adjustment in geriatric patients should be based on a careful assessment of renal function.
In children or adolescents 10-16 years of age receiving metformin hydrochloride 500 mg twice daily as immediate-release tablets or the immediate-release oral solution, daily dosage may be increased by 500 mg at weekly intervals until the desired glycemic response is achieved or a maximum dosage of 2 g daily given in 2 divided doses is reached.
Because of the risk of lactic acidosis, which occurs rarely but may be fatal, metformin should not be used in patients with severe renal disease or dysfunction (eGFR less than 30 mL/minute per 1.73 m2) and should be avoided in those with clinical or laboratory evidence of hepatic disease. In patients with moderate renal disease, the benefits and risks of continuing metformin therapy should be assessed. (See Cautions: Lactic Acidosis.)
An FDA review of clinical studies evaluating the safety of metformin in patients with reduced kidney function suggests that metformin can be used safely in patients with mild impairment in kidney function and in some patients with moderate impairment in kidney function.
The manufacturers and FDA state that renal function (eGFR) should be assessed prior to initiation of metformin and at least annually; more frequent monitoring has been recommended in patients with an increased risk of developing renal impairment (e.g., geriatric patients). The manufacturers and FDA state that initiation of metformin therapy is not recommended in patients with an eGFR between 30-45 mL/minute per 1.73 m2 and that the benefits and risks of continuing the drug should be assessed in those already receiving metformin whose eGFR falls below 45 mL/minute per 1.73
m2. The manufacturers and FDA state that metformin is contraindicated in patients with an eGFR of less than 30 mL/minute per 1.73 m2 and that the drug should be discontinued in patients whose eGFR falls below 30 mL/minute per 1.73 m2 who are already receiving metformin.

Metformin hydrochloride is administered orally. In patients receiving metformin hydrochloride immediate-release tablets at a dosage of 2 g or less daily, the drug usually can be given as 2 divided doses daily; however, in patients who require more than 2 g daily, the drug may be better tolerated if administered in 3 divided doses daily. Immediate-release metformin hydrochloride in fixed combination with canagliflozin, dapagliflozin, empagliflozin, ertugliflozin, pioglitazone, alogliptin, linagliptin, or sitagliptin is administered in divided doses daily with meals to reduce the GI effects of the metformin hydrochloride component.
Although food decreases the extent and slightly delays absorption of metformin immediate-release tablets, the manufacturer recommends that the drug be taken with meals to decrease adverse GI effects. Metformin hydrochloride extended-release tablets usually are taken with the evening meal. The manufacturer of Fortamet(R) (metformin hydrochloride extended-release tablets) states that each dose of the drug should be taken with a full glass of water.
The matrix core of some extended-release tablet preparations (e.g., Glumetza(R)) usually is broken up in the GI tract, but patients should be advised that occasionally the biologically inert components of the tablet may remain intact and be passed in the stool as a soft, hydrated mass. Occasionally, Glumetza(R) may be eliminated in the feces as a soft, hydrated mass or an insoluble shell. The membrane coating surrounding the core of another extended-release tablet (Fortamet(R)) remains intact through the GI tract and is excreted in feces as a soft mass that may resemble the original tablet.
(See Chemistry and Stability: Stability.) Extended-release metformin hydrochloride in fixed combination with canagliflozin, dapagliflozin, or empagliflozin is administered once daily with the morning meal. The fixed combination of extended-release metformin hydrochloride and linagliptin should be administered once daily with a meal. The fixed combination of extended-release metformin hydrochloride and sitagliptin should be administered once daily with a meal, preferably with the evening meal.
Extended-release metformin hydrochloride in fixed combination with saxagliptin should be administered once daily with the evening meal. Extended-release metformin hydrochloride tablets and fixed-combination preparations containing the extended-release form of the drug must be swallowed whole and not chewed, cut, or crushed; inactive ingredients occasionally may be eliminated in feces as a soft mass that may resemble the original tablet.

| Drug Interaction | Drug Names |
|---|---|
| Metformin/Iodinated Contrast Materials SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Use of iodinated contrast materials may result in acute changes in renal function, resulting in a decrease in metformin clearance.(1-3) CLINICAL EFFECTS: Use of iodinated contrast materials may increase levels of metformin, which may result in lactic acidosis.(1-3) PREDISPOSING FACTORS: Pre-existing renal dysfunction may contribute to decreased clearance of metformin. Other factors which may increase the risk for lactic acidosis include age greater than 65 years, dehydration, metabolic acidosis, sepsis, a history of hepatic impairment, alcoholism, or heart failure.(1-4) PATIENT MANAGEMENT: Evaluate renal function prior to contrast procedure. According to manufacturer recommendations, discontinue metformin at the time of, or prior to, the contrast imaging procedure in patients with a history of liver disease, alcoholism, heart failure, or if contrast is to be administered intra-arterially. When contrast is to be administered by other routes, discontinue metformin at the time of, or prior to, the procedure for patients with an estimated glomerular filtration rate (eGFR) of 30 to 60 mL/min/1.73 m2. Re-evaluate eGFR 48 hours after the imaging procedure and restart metformin if renal function is stable. Discontinuation of metformin is not required if eGFR is > 60 mL/min/1.73 m2.(4) According to American College of Radiology guidelines, discontinue metformin at the time of, or prior to, the contrast imaging procedure in patients with acute kidney injury or chronic kidney disease (Stage IV or V or eGFR < 30 mL/min/1.73 m2), or who are undergoing arterial catheter studies that might result in emboli (atheromatous or other) to the renal arteries. Re-evaluate eGFR 48 hours after the imaging procedure and restart metformin if renal function is normal. Discontinuation of metformin is not required in patients with no evidence of acute kidney injury and with eGFR >= 30 mL/min/m2.(5) DISCUSSION: An FDA review of the medical literature showed that metformin may be safely used in patients with mild or moderate renal impairment, resulting in modifications of prescribing recommendations and method for evaluation of renal function.(4) A clinical review of 33 patients on metformin who had received contrast media showed elevations in serum creatinine of the four patients with baseline elevations. The 29 patients with normal baseline renal function showed no elevations after administration of contrast media. The authors recommend that a baseline serum creatinine is obtained for all patients and that metformin should only be discontinued in patients with baseline elevations.(6) A retrospective study of ninety-seven patients currently taking metformin underwent a radiologic procedure with contrast media. Of these patients, 4 developed contrast material associated nephropathy and eight patients had an increased risk of lactic acidosis, with a baseline serum creatinine <1.5mg/dl.(7) A prospective clinical trial with 50 diabetic patients on metformin with baseline serum creatinine <1.47mg/dl showed no statistical difference in renal function before and 48 hours after administration of contrast media. The authors recommend a baseline serum creatinine for all patients and suggest that temporary discontinuation of metformin may not be necessary when baseline renal function is <1.47mg/dl.(8) A systematic review of the literature reveals that 17 of 18 case reports of metformin-induced lactic acidosis involved patients with renal dysfunction prior to administration of contrast media. The authors recommend a baseline serum creatinine in all patients and if renal dysfunction is present, metformin should be discontinued for 48 hours before and after administration of contrast media. The authors recommend follow-up creatinine measurement in patients with prior renal impairment or known comorbidities affecting lactate levels.(9) |

| Antidiabetic Agents/Gatifloxacin SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: The exact mechanism is unknown. CLINICAL EFFECTS: Concurrent use of gatifloxacin may result in hypoglycemia and/or hyperglycemia.(1-4) Hypoglycemia is more common during the first three days of concurrent therapy. Hyperglycemia is more common after the first three days of concurrent therapy.(2) PREDISPOSING FACTORS: Elderly patients, especially those with decreased renal function may be predisposed to this interaction.(2) PATIENT MANAGEMENT: Patients receiving concurrent gatifloxacin should be closely monitored for hypoglycemia during the first three days of concurrent therapy and for hyperglycemia after the first three days of concurrent therapy. Patients should be instructed to discontinue gatifloxacin if hypoglycemia or hyperglycemia occur.(2) DISCUSSION: Hypoglycemia has been reported with gatifloxacin and glyburide(1,5,6) or glimepiride.(7) In a study in patients with type 2 diabetes mellitus, concurrent gatifloxacin (400 mg daily for 10 days) had no effect on the pharmacokinetics of glyburide (steady state daily regimen); however, pharmacodynamic interactions have been reported.(2) Health Canada has received 19 reports of hypoglycemia in patients taking gatifloxacin. Seventeen of these involved concurrent hypoglycemic agents. Health Canada has received 2 reports of hyperglycemia in patients taking gatifloxacin and hypoglycemic agents. Health Canada has received 2 reports of patients experiencing hypoglycemia and hyperglycemia during concurrent gatifloxacin and hypoglycemic agents.(3) In a study, 13 reports of dysglycemia were reported in patients taking gatifloxacin. Ten of these patients had diabetes mellitus and were on concurrent hypoglycemic agents. Of these ten patients, nine patients experienced hypoglycemia, while one patient experienced hyperglycemia.(8) |
GATIFLOXACIN SESQUIHYDRATE |
| Metformin/Tafenoquine SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Metformin renal clearance is mediated by OCT2 and MATE1 transporters.(1) Tafenoquine inhibits elimination by these pathways.(2) CLINICAL EFFECTS: Use of tafenoquine may increase levels of metformin, which may result in lactic acidosis. PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment, sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels > 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. PATIENT MANAGEMENT: The US labeling for metformin recommends the dose of metformin be adjusted as needed.(1) The manufacturer of tafenoquine states the concurrent administration of tafenoquine with OCT2 and MATE1 substrates, such as metformin, should be avoided. If coadministration cannot be avoided, monitor for drug-related toxicities.(2) Evaluate patient's renal function and consider discontinuation in patients with renal impairment. Monitor for signs and symptoms of metformin toxicity (lactic acidosis) such as malaise, myalgias, respiratory distress, increasing somnolence, and respiratory distress. Laboratory results which may signal lactic acidosis include: elevated blood lactate levels (greater than 5 mmol/L), low pH, an increased anion gap, and increased lactate to pyruvate ratio. DISCUSSION: Metformin renal clearance is mediated by OCT2 and MATE1 transporters.(1) Tafenoquine is believed to inhibit the OCT2 and MATE1 pathways.(2) |

There are 11 moderate interactions.
The clinician should assess the patient’s characteristics and take action as needed. Actions required for moderate interactions include, but are not limited to, discontinuing one or both agents, adjusting dosage, altering administration.
| Drug Interaction | Drug Names |
|---|---|
| Metformin/MATE Inhibitors SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Inhibitors of the Multidrug and Toxin Extrusion (MATE) protein transporters in the kidneys may interfere with the renal tubular secretion of metformin.(1) CLINICAL EFFECTS: Concurrent use may result in increased plasma levels of metformin and toxicity such as lactic acidosis. Untreated lactic acidosis may be fatal. Symptoms of lactic acidosis include malaise, myalgias, respiratory distress, low pH, increased anion gap and elevated blood lactate. PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment,sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels > 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. The risk for metabolic acidosis is higher with increased doses of either agent. PATIENT MANAGEMENT: Use an alternative agent if possible. If both drugs are given, monitor patient's renal function and for signs and symptoms of metformin toxicity (lactic acidosis) such as malaise, myalgias, respiratory distress, increasing somnolence, and respiratory distress. Laboratory results which may signal lactic acidosis include: low pH, an increased anion gap, and increased lactate to pyruvate ratio. Dosage of either agent may need to be adjusted.(1) DISCUSSION: In a study of normal healthy volunteers, concurrent metformin and oral cimetidine increased metformin maximum concentration (Cmax) in plasma and whole blood by 60% and increased metformin area-under-curve (AUC) levels in plasma and whole blood by 40%.(1) In a study in 7 subjects, concurrent metformin (250 mg daily) with cimetidine (400 mg twice daily) increased metformin AUC by 50%. Metformin renal clearance over 24 hours was reduced by 27%.(2) MATE inhibitors include: cimetidine, pyrimethamine, and risdiplam.(3) |
CIMETIDINE, DARAPRIM, EVRYSDI, PYRIMETHAMINE |
| Metformin/Cephalexin SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Cephalexin may inhibit the renal tubular secretion of metformin.(1,2) CLINICAL EFFECTS: Concurrent use of cephalexin may result in increased levels and clinical effects of metformin,(1,2) as well as an increased risk of lactic acidosis. PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment, sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels > 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. PATIENT MANAGEMENT: Patients maintained on metformin should be closely monitored when cephalexin is initiated and discontinued. The dosage of metformin may need to be adjusted.(1) DISCUSSION: In a randomized, cross-over study in 12 healthy subjects, concurrent metformin (500 mg) and cephalexin (500 mg) increased the maximum concentration (Cmax) and area-under-curve (AUC) of metformin by 34% and 24%, respectively. Metformin renal clearance decreased by 14%.(1,2) |
CEPHALEXIN |
| Metformin/Ranolazine SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Ranolazine may decrease renal elimination of metformin by inhibiting OCT-2.(1) CLINICAL EFFECTS: Concurrent ranolazine may result in elevated levels of and toxicity from metformin.(1) PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment, sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels > 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. PATIENT MANAGEMENT: Monitor patients receiving concurrent therapy with metformin and ranolazine. In patients receiving 1000 mg ranolazine twice daily, limit the dose of metformin to 1700 mg daily.(1) DISCUSSION: In healthy subjects, ranolazine (1000 mg twice daily) increased exposure of metformin by 80%. Ranolazine (500 mg BID) increased metformin exposure by 40%.(1) |
ASPRUZYO SPRINKLE, RANOLAZINE ER |
| Metformin/Carbonic Anhydrase Inhibitors SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Carbonic anhydrase inhibitors increase bicarbonate excretion which may cause metabolic acidosis.(1) High systemic concentrations of metformin may result in lactic acidosis.(2,3) Topiramate, a mild carbonic anhydrase inhibitor, may also increase systemic exposure to metformin.(1) CLINICAL EFFECTS: Carbonic anhydrase inhibitors may increase the risk for metformin associated lactic acidosis.(1-3) Untreated lactic acidosis may be fatal. Symptoms of lactic acidosis include malaise, myalgias, respiratory distress, low blood pH, increased anion gap and elevated blood lactate.(2) Carbonic anhydrase inhibitors linked to this monograph are acetazolamide, dichlorphenamide, methazolamide, sulthiame, topiramate, and zonisamide. PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment,sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels > 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. The risk for metabolic acidosis is higher with increased doses of either agent. PATIENT MANAGEMENT: For patients receiving concurrent therapy, monitor renal function and assure that patient does not have risk factors for metformin associated lactic acidosis. Discontinue metformin when risk factors are present. If both drugs are given, monitor renal function and for signs and symptoms of metformin toxicity (lactic acidosis) such as malaise, myalgias, respiratory distress, increasing somnolence, and respiratory distress. Laboratory results which may signal lactic acidosis include: low pH, an increased anion gap, and increased lactate to pyruvate ratio. Manufacturer recommendations: the manufacturer of metformin recommends caution with concomitant use of carbonic anhydrase inhibitors due to an increased risk for metformin associated lactic acidosis.(2) The manufacturer of topiramate notes that topiramate can frequently cause metabolic acidosis and that metformin should not be used in patients with metabolic acidosis.(1) DISCUSSION: A literature search for lactic acidosis due solely to the combination of metformin and carbonic anhydrase inhibitors or topiramate did not reveal any case reports of symptomatic metabolic acidosis due to this combination. Never-the-less, since carbonic anhydrase inhibitors act by inhibiting the reabsorption of bicarbonate in the renal tubule, some lowering of systemic bicarbonate and pH is common and supports the plausibility of this interaction. In addition, a pharmacokinetic interaction has been described with topiramate. A study in healthy volunteers evaluated the effect of topiramate 100 mg every 12 hours on the kinetics of metformin 500 mg every 12 hours. Mean metformin exposure (area-under-curve or AUC) was increased 25%.(1) |

| Metformin/Dolutegravir SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Dolutegravir may inhibit the renal organic cation transporter, OCT2, responsible for the elimination of metformin.(1) CLINICAL EFFECTS: Concurrent use may result in increased plasma levels of metformin and toxicity such as lactic acidosis. Untreated lactic acidosis may be fatal. Symptoms of lactic acidosis include malaise, myalgias, respiratory distress, low pH, increased anion gap and elevated blood lactate. PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment,sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels > 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. PATIENT MANAGEMENT: With concomitant use, assess the benefit and risk of metformin in patients on dolutegravir. When starting or stopping dolutegravir, the metformin dose may require an adjustment. Monitor blood glucose when initiating concomitant use and after stopping dolutegravir.(1) Monitor patient's renal function and for signs and symptoms of metformin toxicity (lactic acidosis) such as malaise, myalgias, respiratory distress, increasing somnolence, and respiratory distress. Laboratory results which may signal lactic acidosis include: low pH, an increased anion gap, and increased lactate to pyruvate ratio.(1) DISCUSSION: Dolutegravir has been shown to inhibit OCT2 in vitro and in vivo and is expected to inhibit the excretion of metformin.(1) In a study in 15 subjects, concomitant metformin (500 mg twice daily) with dolutegravir (50 mg daily) increased the concentration maximum (Cmax) and area-under-curve (AUC) of metformin by 66% and 79%, respectively. In a study in 15 subjects, concomitant metformin (500 mg twice daily) with dolutegravir (50 mg twice daily) increased the Cmax and AUC of metformin by 111% and 145%, respectively.(1) |

| Metformin/Trimethoprim SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Metformin renal clearance is mediated by OCT2 and MATE1 transport. Trimethoprim inhibits elimination by these pathways. CLINICAL EFFECTS: Use of trimethoprim may increase levels of metformin, which may result in lactic acidosis. PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment,sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels > 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. PATIENT MANAGEMENT: The US labeling for metformin recommends the dose of metformin and/or trimethoprim be adjusted as needed. Consider the benefits and risks of concomitant use.(1) Evaluate patient's renal function and consider discontinuation of one or both agents in patients with renal impairment. Monitor for signs and symptoms of metformin toxicity (lactic acidosis) such as malaise, myalgias, respiratory distress, increasing somnolence, and respiratory distress. Laboratory results which may signal lactic acidosis include: elevated blood lactate levels (greater than 5 mmol/L), low pH, an increased anion gap, and increased lactate to pyruvate ratio. DISCUSSION: Trimethoprim was found to cause significant inhibition of net transcellular chloroquine transport in canine kidney-OCT2-MATE1 cells. Chloroquine is eliminated by renal tubular secretion involving multidrug and toxin extrusion protein 1 (MATE1). Trimethoprim caused concentration-dependent inhibition of net metformin intake in HEK293-MATE1 cells (human embryonic kidney). (2) A randomized, open-label, two-phase crossover study found that trimethoprim inhibited OCT2, MATE1, and MATE2-K-dependent transport of metformin. Trimethoprim increased metformin area under the curve (AUC) by 29.4% and decreased metformin renal clearance by 26.4%. (3) 24 healthy volunteers received metformin 500 mg three times daily for ten days and trimethoprim 200 mg twice daily from days 5-10. Trimethoprim significantly reduced the apparent systemic metformin clearance (CL/F) from 74 to 54 l/h and renal metformin clearance from 31 to 21 l/h. Metformin half-life was prolonged from 2.7 to 3.6h. The metformin plasma concentration (Cmax) increased 38% and the AUC by 37%. Trimethoprim was also associated with a decrease in creatinine clearance and an increase in plasma lactate. (4) |

| Metformin/Vandetanib SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Renal tubular secretion of metformin is mediated by organic cation transporter 2 (OCT2) and the multidrug and toxin extrusion protein (MATE) transporter. Vandetanib inhibits elimination by the OCT2 and MATE pathways.(1) CLINICAL EFFECTS: Use of vandetanib may increase levels of metformin. Concurrent use may result in increased plasma levels of metformin and toxicity such as lactic acidosis. Untreated lactic acidosis may be fatal. Symptoms of lactic acidosis include malaise, myalgias, respiratory distress, low pH, increased anion gap and elevated blood lactate.(1) PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment, sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels > 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. The risk for metabolic acidosis is higher with increased doses of either agent. PATIENT MANAGEMENT: Use an alternative agent if possible. The US labeling for vandetanib recommends caution with concomitant use of metformin and close monitoring for metformin toxicity.(1) Evaluate patient's renal function and consider discontinuation of one or both agents in patients with renal impairment. Monitor for signs and symptoms of metformin toxicity (lactic acidosis) such as malaise, myalgias, respiratory distress, increasing somnolence, and respiratory distress. Laboratory results which may signal lactic acidosis include: elevated blood lactate levels (greater than 5 mmol/L), low pH, an increased anion gap, and increased lactate to pyruvate ratio. DISCUSSION: A study in 13 healthy subjects receiving a single 1,000 mg dose of metformin 3 hours after a single 800 mg dose of vandetanib resulted in increases in metformin area-under-curve (AUC) of 74% and maximum concentration (Cmax) of 50% with coadministration compared to metformin alone.(1) In a study of normal healthy volunteers, concurrent metformin and oral cimetidine (MATE inhibitor) increased metformin maximum concentration (Cmax) in plasma and whole blood by 60% and increased metformin area-under-curve (AUC) levels in plasma and whole blood by 40%.(1) In a study in 7 subjects, concurrent metformin (250 mg daily) with cimetidine (400 mg twice daily) increased metformin AUC by 50%. Metformin renal clearance over 24 hours was reduced by 27%.(2) |

| Patiromer/Metformin SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Patiromer may bind to metformin.(1) CLINICAL EFFECTS: Concurrent use may result in decreased gastrointestinal absorption and loss of efficacy of metformin.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The US manufacturer of patiromer recommends that you administer patiromer at least 3 hours before or 3 hours after metformin.(1) DISCUSSION: A study in healthy volunteers showed that patiromer decreased the systemic exposure of coadministered metformin. No interaction was seen when these drugs were taken 3 hours apart.(1) |

| Metformin/Bictegravir SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Metformin renal clearance is mediated by OCT2 and MATE1 transport. Bictegravir inhibits elimination by these pathways.(1,2) CLINICAL EFFECTS: Use of bictegravir may increase levels of metformin, which may result in lactic acidosis. PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment,sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels > 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. PATIENT MANAGEMENT: The US labeling for metformin recommends the dose of metformin be adjusted as needed.(1) Evaluate patient's renal function and consider discontinuation of one or both agents in patients with renal impairment. Monitor for signs and symptoms of metformin toxicity (lactic acidosis) such as malaise, myalgias, increasing somnolence, and respiratory distress. Laboratory results which may signal lactic acidosis include: elevated blood lactate levels (greater than 5 mmol/L), low pH, an increased anion gap, and increased lactate to pyruvate ratio. DISCUSSION: Bictegravir is an inhibitor of OCT2 and MATE1.(2) Trimethoprim, an inhibitor of OCT2 and MATE1, was found to cause significant inhibition of net transcellular chloroquine transport in canine kidney-OCT2-MATE1 cells. Chloroquine is eliminated by renal tubular secretion involving multidrug and toxin extrusion protein 1 (MATE1). Trimethoprim caused concentration-dependent inhibition of net metformin intake in HEK293-MATE1 cells (human embryonic kidney).(3) A randomized, open-label, two-phase crossover study found that trimethoprim inhibited OCT2, MATE1, and MATE2-K-dependent transport of metformin.

| Selected Antidiabetic Agents/Chloroquine; Hydroxychloroquine SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: The exact mechanism is unknown. Chloroquine and hydroxychloroquine may increase insulin sensitivity by inhibiting insulin metabolism and inflammation and increasing cellular uptake of glucose and glycogen synthesis.(1,2) These effects may result in additive hypoglycemia with anti-diabetic agents. CLINICAL EFFECTS: Concurrent use of chloroquine or hydroxychloroquine and antidiabetic agents may result in severe hypoglycemia.(3) Hypoglycemia can lead to coma. PREDISPOSING FACTORS: Elderly patients, especially those with decreased renal function may be predisposed to this interaction. PATIENT MANAGEMENT: Patients maintained on antidiabetic agents who require concurrent therapy with chloroquine or hydroxychloroquine should be closely monitored for hypoglycemia. A decrease in the dose of insulin or other anti-diabetic medications may be required. Patients should be advised of the risk and symptoms of hypoglycemia and to contact their doctor if hypoglycemia occurs.(3) Signs of hypoglycemia may include confusion, dizziness, feeling shaky, unusual hunger, headaches, irritability, pounding heart or very fast pulse, pale skin, sweating, trembling, weakness, or unusual anxiety. DISCUSSION: Hydroxychloroquine has been shown to cause severe hypoglycemia including loss of consciousness that could be life threatening.(3) Concomitant hypoglycemic agents may increase the risk and/or severity of this effect. A 77 year old man who was stable on twice daily insulin suffered two episodes of hypoglycemic coma 2 weeks after starting prednisone 5 mg daily and hydroxychloroquine 400 mg daily for rheumatoid arthritis. His insulin dosage required a decrease of 37%.(4) Many studies have investigated the glucose-lowering effect of hydroxychloroquine. In a clinical trial of type II diabetics on maximal doses of sulfonylureas, addition of hydroxychloroquine lowered hemoglobin A1C (HbA1C) up to 1% more than placebo.(5) Another clinical trial of type II diabetics on metformin and glimepiride or gliclazide found that hydroxychloroquine 400 mg daily reduced fasting blood glucose (FBG), post-prandial glucose (PPG), and HbA1C to a similar degree as pioglitazone 15 mg daily at 24 weeks.(6) In a prospective observational study, 250 uncontrolled type II diabetics on metformin, glimepiride, pioglitazone, sitagliptin, and a SGLT-2 inhibitor received hydroxychloroquine 400 mg daily for 48 weeks. HbA1C decreased from 8.83% to 6.44%, FBG decreased by 40.78%, and PPG decreased by 58.95%. The doses of metformin were reduced by 50%, glimepiride and sitagliptin by 75%, and SGLT-2 inhibitors were discontinued in most patients.(7) |

| Metformin/OCT2 Inhibitors SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Agents that inhibit the organic cation transporter 2 (OCT2) may inhibit the excretion of metformin by OCT2 in the kidneys.(1) CLINICAL EFFECTS: Concurrent use of OCT2 renal transport inhibitors may result in increased levels of and toxicity from metformin.(1) PREDISPOSING FACTORS: Risk factors for metformin associated lactic acidosis include renal impairment, sepsis, dehydration, excessive alcohol intake, acute or chronic metabolic acidosis, hepatic insufficiency, acute heart failure, metformin plasma levels higher than 5 micrograms/mL, and conditions which may lead to tissue hypoxia. Geriatric patients may also be at higher risk due to slower metformin clearance and increased half-life in this population. PATIENT MANAGEMENT: Consider the potential benefits against the risks of concurrent use of metformin with OCT2 renal transport inhibitors. If concurrent use is appropriate, monitor for toxicities of metformin and consider dosage reduction of metformin.(1) DISCUSSION: In a study, givinostat increased the levels of creatinine (OCT2 substrate) by 4.76 umol/L from baseline.(1) OCT2 inhibitors linked to this monograph include: arimoclomol, givinostat, trilaciclib, and vimseltinib.(2) |

Reproduction studies in rats and rabbits given metformin hydrochloride dosages of 600 mg/kg daily (about twice the maximum recommended human daily dosage based on body surface area or about 3 and 6 times the maximum recommended human daily dosage of extended-release tablets (2 g) based on body surface area comparisons with rats and rabbits, respectively) have not revealed evidence of harm (e.g., teratogenicity) to the fetus. Determination of fetal concentrations of metformin suggest that a partial placental barrier to the drug exists. Since abnormal maternal blood glucose concentrations during pregnancy may be associated with a higher incidence of congenital abnormalities, most experts recommend that insulin be used during pregnancy to maintain optimum control of blood glucose concentration.
The estimated background risk of major birth defects is 6-10% in women with pre-gestational diabetes mellitus who have an HbA1c exceeding 7 and has been reported to be as high as 20-25% in women with a HbA1c exceeding 10. The estimated background risk of miscarriage for the indicated population is unknown. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Available studies on the use of metformin in pregnant women have not reported a clear association with metformin and major birth defects, miscarriage, or adverse maternal or fetal outcomes. Limited data from uncontrolled or retrospective studies are conflicting with regard to the effects of long-term maternal therapy with metformin hydrochloride (1.5-3 g daily) on neonatal morbidity (e.g., congenital malformations) and mortality. Poorly controlled diabetes mellitus in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, and delivery complications.
Poorly controlled diabetes mellitus increases the fetal risk for major birth defects, stillbirth, and macrosomia-related morbidity. Metformin should be used during pregnancy only when clearly needed.

Metformin is distributed into milk in lactating rats. Limited data indicate that small amounts of metformin also are distributed into breast milk in humans. In a study in 7 nursing women who received metformin hydrochloride (median dosage 1500 mg daily), the mean milk-to-plasma ratio for metformin was 0.35
and the overall average concentration in milk over the dosing interval was 0.27 mg/L. Metformin was present in low or undetectable amounts in the plasma of 4 breast-fed infants, and no adverse effects were noted in 6 infants that were evaluated.
In another study, mean peak and trough metformin concentrations in 4 nursing women receiving metformin hydrochloride 500 mg twice daily were 1.06 and 0.42 mcg/mL, respectively, in serum and 0.42
and 0.39 mcg/mL, respectively, in breast milk. The mean milk-to-serum ratio was 0.63
and the mean estimated infant dose as a percentage of the mother's weight-adjusted dose was 0.65%. Blood glucose concentrations obtained in 3 infants 4 hours after breastfeeding were within normal limits (47-77 mg/dL).
The developmental and health benefits of breastfeeding should be considered along with mother's clinical need for the drug and potential adverse effects on the breastfed child (e.g., hypoglycemia). Breastfed infants should be monitored for signs of hypoglycemia (e.g., jitters, cyanosis, apnea, hypothermia, excessive sleepiness, poor feeding, seizures).
