Positive Urine Glucose While Taking an SGLT2 Medicine?

A flagged glucose result on a urine report can be expected with an SGLT2 medicine. The US Jardiance (empagliflozin) label says medicines in this class increase glucose excretion into urine and lead to positive urine-glucose tests.¹

Ask what the test was intended to measure

The label says urine-glucose testing is not recommended for monitoring blood-sugar control during SGLT2 treatment. It also identifies 1,5-anhydroglucitol, or 1,5-AG, as unreliable for that purpose and calls for alternative monitoring methods.¹

If you use a home urine strip, tell the diabetes team exactly which product and result you are looking at. Ask which measurements they want you to use and when to review them. Keep any prescribed blood-glucose monitoring plan in place while you clarify the urine result.

A useful question is: “Is this result expected with my medicine, and which result are we using to assess my blood-sugar control?”

A glucose flag is not a UTI diagnosis

Urinalysis checks for blood and white blood cells, while a urine culture identifies common bacteria and may help determine whether antibiotics are an option. NIDDK² describes diagnosis as a combination of medical history, examination and laboratory testing.²

That is a different assessment from finding glucose. Ask the clinician to explain the relevant parts of the full report alongside your symptoms, rather than judging infection from the glucose line alone.

Contact a healthcare professional for burning when urinating, frequent or intense urges, lower-abdominal discomfort, or cloudy, bloody or strong-smelling urine. Seek prompt care for fever and chills, nausea or vomiting, or back, side or groin pain, which the institute lists as possible kidney-infection symptoms.³

Mention a recent interruption, too

The Jardiance label says urinary glucose excretion can persist for three days after stopping, with longer-lasting glucosuria reported after SGLT2 discontinuation.¹

If a clinician has told you to interrupt the medicine, include the last dose date when discussing a subsequent urine test. Do not use that test to decide when to restart; ask for the restart instructions attached to your treatment plan.

Feeling unwell changes the question

Ketoacidosis can occur with blood glucose less than 250 mg/dL. The Jardiance Medication Guide instructs patients to stop the medicine and obtain immediate medical help for symptoms including nausea, vomiting, abdominal pain, tiredness or trouble breathing, or ketones in blood or urine.¹

A discussion about an expected glucose finding should never become reassurance to wait through those symptoms. Tell the treating team that you take empagliflozin and bring the medication list.

For a routine result discussion, put three items together: the complete report, the medicine name and dose, and a dated symptom note. The “What to Say in the Room” section of Laugh, Sneeze, Jump asks readers to bring their bladder record and a list of every medicine. Add the urine-test date so the clinician can connect the result with what you were taking at the time.
