Empagliflozin: uses, dosing, side effects & brands

JARDIANCE tablets for oral use contain empagliflozin, an inhibitor of the sodium-glucose co-transporter 2 (SGLT2).

The elimination half-life of empagliflozin is about 12 hours (apparent terminal elimination half-life ~12.4 h) — that is how long the body takes to clear half of a dose. Not a prodrug and has no active metabolite — the label reports no major metabolites in human plasma; empagliflozin is cleared mainly by UGT glucuronidation (to inactive conjugates) plus fecal and urinary excretion. Drug exposure rises when the kidneys or liver are impaired, so it clears more slowly: AUC increases roughly 18%/20%/66% in mild/moderate/severe renal impairment (and ~48% in dialysis patients), and roughly 23%/47%/75% in mild/moderate/severe hepatic impairment. Half-life is not the same as how long a drug test can detect the drug, and it varies with age, kidney and liver function.

It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run empagliflozin against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.

Across the brands we track, empagliflozin is currently marketed as tablet, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.

We do not currently list a generic-labelled empagliflozin product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.

The FDA's Enforcement database lists 1 recall record whose product description mentions empagliflozin. The most recent: Synjardy XR Tablets (empagliflozin and metformin hydrochloride extended-release… (Jun 12, 2026). A recall applies to specific lots, not to the drug as a whole — check the record for the affected lot numbers.

The most common are genital yeast infections (itching, soreness, discharge, or irritation under the foreskin) and urinary tract infections, plus more urination and thirst. The extra urination usually eases over the first few weeks as your body adjusts. Genital infections respond to standard antifungal treatment, but they can come back while you keep taking the drug, because empagliflozin works by pushing sugar out in your urine and sugar feeds yeast. This answer is for the oral tablet (Jardiance and its combination pills), the only form sold; the label's usual dose is 10 mg once daily in the morning, with or without food.

Two stand out. First, ketoacidosis, which with this drug class can happen even when your blood sugar reads below the level usually expected for it (under 250 mg/dL), so a near-normal glucose does not rule it out; the label records fatal cases in type 2 diabetes, not only type 1. Warning signs: nausea, vomiting, belly pain, feeling generally unwell, unusual tiredness, and shortness of breath or deep rapid breathing. Second, Fournier's gangrene, a rare necrotizing infection of the perineum: pain, tenderness, redness, or swelling between the genitals and anus plus fever or malaise. It needs urgent surgery. Also urgent: fever with flank or back pain (the label warns of pyelonephritis and urosepsis needing hospitalization), and swelling of the face, lips, or tongue, which the label lists as serious hypersensitivity including angioedema.

The label names the precipitants: insulin dose reduction or missed insulin doses, acute febrile illness, reduced calorie intake, ketogenic eating, surgery, volume depletion, and alcohol abuse. FDA labeling directs withholding empagliflozin for at least 3 days before scheduled surgery or any procedure involving prolonged fasting, and restarting only once you are eating normally and the other risk factors have resolved. Do not stop insulin on your own if you use it. On sick days, keep fluids up, and if you can test ketones, test when you feel unwell even with a normal glucose reading. Empagliflozin is not recommended for type 1 diabetes because it raises ketoacidosis risk in that group.

Take it in the morning so the extra urination does not wake you at night. Rinse and dry the genital area after urinating and change out of damp clothing; the label notes that a history of chronic or recurrent genitourinary infection makes another one more likely, so report itching early rather than waiting. Check your feet: the label carries a lower limb amputation warning and instructs monitoring for foot infections or ulcers, so get any sore, blister, or non-healing spot looked at promptly. Dizziness on standing usually means volume depletion, more likely if you also take a loop diuretic, are elderly, or have reduced kidney function; keep fluids up and ask about adjusting the diuretic. Empagliflozin alone rarely causes low blood sugar, but when added to insulin or a sulfonylurea, those doses often need lowering.
