Applies to empagliflozin / metformin: oral tablet, oral tablet extended release
Oral route (Tablet; Tablet, Extended Release)
Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. Symptoms included malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Laboratory abnormalities included elevated blood lactate levels, anion gap acidosis, increased lactate/pyruvate ratio, and metformin plasma levels generally greater than 5 mcg/mL. Risk factors include renal impairment, concomitant use of certain drugs (eg, carbonic anhydrase inhibitors such as topiramate), age 65 years or older, radiological study with contrast, surgery and other procedures, hypoxic states, excessive alcohol intake, and hepatic impairment. If lactic acidosis is suspected, discontinue empagliflozin/metformin hydrochloride and institute general supportive measures in a hospital setting.
Along with its needed effects, empagliflozin / metformin may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Check with your doctor immediately if any of the following side effects occur while taking empagliflozin / metformin:
Incidence not known
Some side effects of empagliflozin / metformin may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:

Empagliflozin: The most frequently reported side effects included urinary tract infections and female genital mycotic infections.
Metformin: The most frequently reported side effects included diarrhea, nausea, vomiting, flatulence, abdominal discomfort, indigestion, asthenia, and headache.
Empagliflozin is known to cause osmotic diuresis, leading to intravascular volume contraction and adverse reactions related to volume depletion. Adverse reactions related to volume depletion such as decreased ambulatory/systolic blood pressure, dehydration, hypotension, hypovolemia, orthostatic hypotension, and syncope were reported in 0.5% and 0.3% of patients receiving empagliflozin 10 mg (n=999) or 25 mg (n=977) orally once a day, respectively.
Uncommon (0.1% to 1%): Hypotension, orthostatic hypotension, syncope, decreased systolic blood pressure, decreased ambulatory blood pressure
During a 24 week study of empagliflozin in combination with metformin plus a sulfonylurea, urinary tract infections (UTIs) were reported in 9.4% and 6.9% of patients receiving empagliflozin 10 mg (n=224) or 25 mg (n=217) once a day, respectively. Pooled data from 5 studies showed the incidence of UTIs (e.g., UTI, asymptomatic bacteriuria, and cystitis), was increased in empagliflozin-treated patients compared to placebo, more frequent in females compared to males, and more likely to occur in patients with a history of chronic or recurrent UTIs. Treatment discontinuation due to UTIs occurred in 0.2% and 0.1% of patients receiving empagliflozin 10 mg or 25 mg once a day, respectively.
In the 5 years (2013 to 2018) since SGLT2 inhibitor approval, 12 cases of Fournier's gangrene have been reported. Reports were almost equal in men and women (men=7; women=5), ages ranged from 38 to 78 years, and the average time to onset after starting an SGLT2 inhibitor was 9.2 months (range 7 days to 25 months). All SGLT2 inhibitor drugs except ertugliflozin were included in the reports. Ertugliflozin being the most recently approved agent, is expected to have the same risk, but insufficient patient use to assess risk. All patients were hospitalized, all required surgery, all required surgical debridement, 5 required more than 1 surgery and 1 required skin grafting. Four cases were complicated by diabetic ketoacidosis, acute kidney injury, and septic shock, leading to prolonged hospitalization, and death in 1 case. In the general population, Fournier's gangrene occurs in about 1.6 out of 100,000 males annually, with the highest incidence in men 50 to 79 years. Since diabetes is a risk factor for Fournier's gangrene, a review of the FAERS database for the last 34 years was done and only 6 cases (all males, median age 57 years) were found with several other classes of antidiabetic drugs. Findings with SGLT2 inhibitors appear to show an association over a shorter time frame and involve both males and females.
Common (1% to 10%): Urinary tract infections
Common (1% to 10%): Urinary tract infections, female genital mycotic infections, male genital mycotic infections, increased urination (e.g., polyuria, pollakiuria, and nocturia)
Uncommon (0.1% to 1%): Dysuria
Rare (less than 0.1%): Phimosis
Postmarketing reports: Urosepsis, pyelonephritis, Fournier's gangrene
The frequency of hypoglycemia depended on the type of background therapy used. When empagliflozin was used as monotherapy, hypoglycemia was reported in 0.4% of patients taking the 10 mg and 25 mg doses. In combination with metformin, hypoglycemia was reported in 1.8% taking 10 mg and 1.4% taking 25 mg. In combination with metformin and a sulfonylurea, hypoglycemia was reported in 16.1% taking the 10 mg dose and 11.5% taking the 25 mg dose. In combination with basal insulin, hypoglycemia was reported in 19.5% taking the 10 mg dose and 28.4% taking the 25 mg dose.
Twenty reports of acidosis, including diabetic ketoacidosis (DKA), ketoacidosis, or ketosis in patients treated with SGLT-2 inhibitors have been identified in the US Food and Drug Administration Adverse Event Reporting System (FAERS) database during the period March 2013 through 06 June 2014. All patients required emergency room treatment or hospitalization. These cases were not typical of ketoacidosis or DKA in that they occurred in patients with type 2 diabetes and their blood sugar levels were only slightly increased. Some factors identified as potentially triggering the acidosis included major illness, reduced food and fluid intake, and reduced insulin dose.
Very common (10% or more): Hypoglycemia (15.6%)
