What is Xigduo (the combination drug)?
Xigduo is a brand name for a fixed-dose combination tablet that contains two diabetes medicines: metformin and dapagliflozin. It’s used to help control blood sugar in adults with type 2 diabetes. (The exact dose strengths depend on the specific Xigduo product.)
Why combine metformin with dapagliflozin?
The goal of the Xigduo combination is to target two different mechanisms for lowering glucose:
- Metformin reduces liver glucose production and improves insulin sensitivity.
- Dapagliflozin (an SGLT2 inhibitor) helps the kidneys remove glucose from the bloodstream through urine.
Who is Xigduo typically prescribed for?
Xigduo is generally used for adults with type 2 diabetes when blood sugar is not adequately controlled with lifestyle changes and either metformin or dapagliflozin alone, or when a clinician wants a single tablet that combines both therapies.
What are common safety issues people ask about?
People taking metformin + dapagliflozin combinations often ask about:
- Stomach/GI side effects from metformin (like nausea or diarrhea).
- Genital yeast infections and urinary symptoms related to SGLT2 inhibitors.
- Dehydration/low blood pressure risk, especially in people who are older, on diuretics, or have low fluid intake.
- Diabetic ketoacidosis risk (including rare cases with normal or near-normal blood sugar) associated with SGLT2 inhibitors.
Clinicians may adjust or temporarily stop SGLT2 inhibitors around major surgery or during serious illness to reduce risk.
How does Xigduo compare with taking the two drugs separately?
Xigduo can be simpler than taking separate metformin and dapagliflozin prescriptions because it’s one tablet. Whether it’s equivalent depends on matching the same total daily doses that you would otherwise take separately.
Is Xigduo still protected by patents, and are there cheaper alternatives?
Whether there are generic versions or “authorized” alternatives depends on the specific combination product and jurisdiction.

What to check with your prescriber or pharmacist
To use Xigduo safely, it’s important to confirm:
- Your kidney function suitability for dapagliflozin and metformin.
- The exact tablet strength (metformin mg + dapagliflozin mg).
- Any other medicines that can affect fluid balance, blood pressure, or kidney function (for example, diuretics).
- Sick-day rules (when to hold the SGLT2 component during acute illness) and how to monitor symptoms of infection.
