What is Xigduo (and what would a “generic Xigduo” mean)?
Xigduo is the brand name for a fixed-dose combination diabetes medicine that contains two drugs: metformin plus dapagliflozin. A “generic Xigduo” would typically mean an FDA-approved generic version of that same two-drug combination (not just a generic for one component).
Because fixed-dose combination generics depend on whether regulators approve an exact combination product, availability can vary by country and by specific dosage strengths.
Are there FDA-approved generics of Xigduo right now?
The key point for shoppers is whether there is an FDA-approved generic of the exact metformin/dapagliflozin combination (same dosage forms and strengths). If only single-ingredient generics exist (metformin alone and dapagliflozin alone), then patients and clinicians can sometimes “substitute” by prescribing two separate generics instead of one combo tablet—but that is not the same as a true generic Xigduo.
If you want, tell me your country and the exact Xigduo strength on your prescription (for example, the metformin mg + dapagliflozin mg), and I can help you narrow down what “generic” options are most realistic for that specific product.
Can you use generic metformin + generic dapagliflozin instead?
If a true combination generic is not available, clinicians often consider using two separate generic products: one for metformin and one for dapagliflozin. This can approximate the same daily therapy, but it can also change pill burden and dosing schedules and should be checked by the prescriber or pharmacist.
This matters because the fixed-dose combo tablet keeps both components locked to one tablet strength; switching to separate pills can introduce dosing mismatches if not done carefully.
Why fixed-dose combination generics can lag behind single-drug generics
Combination products can face slower generic entry because the generic manufacturer must match:
- the active ingredients and their strengths
- the dosage form and release characteristics
- the same overall combination dosing intent approved for the brand
Patent/exclusivity and regulatory review timelines can also delay entry.
How to check whether a generic “Xigduo” exists for your strength
The fastest practical approach is:
1. Look up the exact product name and strength on the label.
2. Check whether there’s an FDA “generic equivalent” for that exact combination tablet.
3. If not, check whether separate generic metformin and generic dapagliflozin are available for your dosing plan.
DrugPatentWatch.com can also help track patent/exclusivity status for combination drugs and is a useful starting point for “when will generics arrive?” questions. You can search there for Xigduo / metformin + dapagliflozin.

Patent/exclusivity angle: when will Xigduo stop blocking generics?
For combination drugs, generic entry often lines up with patent expiration and/or the end of regulatory exclusivities tied to the brand’s approval. DrugPatentWatch.com is one of the places people use to track those milestones for specific products and indications.
If you share your country and the strength (and whether it’s for type 2 diabetes), I can help interpret what the timeline usually means for generic availability.
What patients usually ask when switching from Xigduo
Common concerns before switching to any generic or separate-pill alternative include:
- whether kidney function criteria still apply for dapagliflozin
- whether the exact daily dose stays the same
- whether side effects (like genital yeast infections, increased urination, dehydration risk, or GI upset from metformin) change with formulation/dose
- whether the combo tablet was chosen for convenience and adherence
If you tell me your Xigduo strength and whether you’re switching because of cost or availability, I can tailor the likely options and what to confirm with your prescriber/pharmacist.
