What Are Warnings and Precautions for Ertugliflozin?


  • Hypersensitivity to ertugliflozin or any excipient; reactions such as angioedema have occurred
  • Patients on dialysis 

Effects of drug abuse

  • None

Short-Term Effects

  • See “What Are Side Effects Associated with Using Ertugliflozin?”

Long-Term Effects

  • See “What Are Side Effects Associated with Using Ertugliflozin?”


  • Causes intravascular volume contraction; symptomatic hypotension may occur after initiating, particularly in patients with renal impairment, with low systolic blood pressure, on diuretics, or who are elderly; before initiating treatment in patients with one or more risk factors, assess volume status and renal function
  • Renal impairment may occur owing to intravascular volume contraction; before initiating, consider factors that may predispose patients to acute kidney injury, including hypovolemia, chronic renal insufficiency, CHF, and concomitant medications (e.g.zx, diuretics, ACE inhibitors, ARBs, NSAIDs); consider temporarily discontinuing ertugliflozin in any setting of reduced oral intake or fluid loss; monitor for signs and symptoms of acute kidney injury, and, if evident, discontinue drug promptly and institute treatment
  • Genital mycotic infections may occur; patients with a history of genital mycotic infections and uncircumcised males are more susceptible
  • Serious urinary tract infections, including urosepsis and pyelonephritis, requiring hospitalization reported in patients receiving SGLT2 inhibitors
  • Increases risk of urinary tract infections (UTIs), including life-threatening urosepsis and pyelonephritis that started as UTIs
  • Necrotizing fasciitis of the perineum (Fournier gangrene) was reported with SGLT2 inhibitors; signs and symptoms include tenderness, redness, or swelling of the genitals or the area from the genitals back to the rectum, and have a fever above 100.4°F or a general feeling of being unwell; if suspected, discontinue SGLT2 inhibitor and start treatment immediately with broad-spectrum antibiotics and surgical debridement if necessary
  • Dose-related increases in LDL-C reported
  • Lower limb amputations
    • An increased risk for lower limb amputation (primarily of the toe) has been observed in clinical studies with another SGLT2 inhibitor; before initiating, consider factors that may predispose the patient to increased risk of amputations (.g, history of prior amputation, peripheral vascular disease, neuropathy, diabetic foot ulcers)
    • Counsel patients about the importance of routine preventative foot care; monitor patients receiving drugs for signs and symptoms of infection (including osteomyelitis), new pain or tenderness, sores or ulcers involving the lower limbs, and discontinue therapy if these complications occur
  • Ketoacidosis
    • Not indicated for patients with type 1 diabetes mellitus (T1DM); in placebo-controlled trials, the risk of ketoacidosis was increased in patients with T1DM who received SGLT2 inhibitors
    • The risk of ketoacidosis may be greater with higher doses
    • Before initiating therapy, consider factors in inpatient history that may predispose to ketoacidosis, including pancreatic insulin deficiency from any cause, caloric restriction, and alcohol abuse
    • Consider temporarily discontinuing therapy for at least 3 days for patients who undergo scheduled surgery
    • Consider monitoring for ketoacidosis and temporarily discontinuing therapy in other clinical situations known to predispose to ketoacidosis (.g, prolonged fasting due to acute illness or post-surgery); ensure risk factors for ketoacidosis are resolved before restarting therapy
    • Restart once the patient’s oral intake is back to baseline and any other risk factors for ketoacidosis (blood acid buildup) are resolved
  • Drug interactions overview
    • Hypoglycemia risk increased with insulin and insulin secretagogues (e.g., sulfonylureas); a lower dose of insulin or insulin secretagogue may be required
  • Laboratory testing
    • Urine glucose tests are not recommended in patients taking SGLT2 inhibitors, as SGLT2 inhibitors, increase urinary glucose excretion and lead to positive urine glucose tests; use alternative methods to monitor glycemic control
    • The 1,5-AG assay is not recommended, as measurements of 1,5-AG are unreliable in assessing glycemic control in patients taking SGLT2 inhibitors; use alternative methods to monitor glycemic control

Pregnancy & Lactation

  • Based on animal data showing adverse renal effects, not recommended during the second and third trimesters of pregnancy
  • Data are limited in pregnant women and are not sufficient to determine a drug-associated risk of adverse developmental outcomes; there are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy
  • Lactation
    • Not recommended while breastfeeding
    • Unknown if distributed in human breast milk
    • Since human kidney maturation occurs in utero and during the first 2 years of life when lactational exposure may occur, there may be a risk to the developing human kidney
    • Because of the potential for serious adverse reactions in a breastfed infant, advise women that ertugliflozin is not recommended while breastfeeding
