Farxiga vs. Victoza
See how Farxiga and Victoza compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Farxiga is a once-daily pill while Victoza is a once-daily injection, so how each drug is taken is a major practical difference.
Farxiga's most common side effects are genital and urinary infections, while Victoza's are gastrointestinal, so the two drugs rarely overlap in what patients notice.
Both lower blood sugar in type 2 diabetes, but Farxiga also treats heart failure and chronic kidney disease while Victoza is approved to cut cardiovascular events in adults with existing heart disease.
Farxiga vs. Victoza Drug Summary
Farxiga
Farxiga (dapagliflozin) is an SGLT2 inhibitor taken as a once-daily oral tablet. It treats type 2 diabetes and also carries separate FDA approvals for heart failure and chronic kidney disease, working by causing the kidneys to remove excess glucose through urine.
Victoza
Victoza (liraglutide) is a GLP-1 receptor agonist given as a once-daily injection under the skin. It treats type 2 diabetes and is also approved to lower cardiovascular risk in adults with existing heart disease, working by boosting insulin release and slowing digestion.

Farxiga vs. Victoza Pros and Cons
Farxiga
Farxiga's oral form and broad set of approvals across diabetes, heart failure, and kidney disease make it appealing for patients managing more than one condition. It's generally lower cost than Victoza but carries genitourinary infection risks that some patients want to avoid.
Pros
Oral tablet, no injections required
Also approved for heart failure and chronic kidney disease
No boxed warning
Cons
Risk of genital yeast infections and urinary tract infections
Not recommended for glycemic control at low kidney function levels
Rare risk of ketoacidosis even with near-normal blood sugar
Victoza
Victoza has a longer track record for cardiovascular risk reduction in people with established heart disease, delivered through a daily self-injection. It avoids the genitourinary infection risks seen with Farxiga but carries its own boxed warning and gastrointestinal side effects.
Pros
Specifically approved to reduce cardiovascular events in adults with heart disease
No genital or urinary infection risk
Long-standing approval history since 2010
Cons
Boxed warning for thyroid C-cell tumor risk
