Januvia vs. Victoza

See how Januvia and Victoza compare on approved uses, dosing, side effects, and cost.

Key Takeaways

  • Januvia is a once-daily pill while Victoza is a once-daily injection, so daily routine and comfort with needles often drive the choice between them.

  • Victoza carries a boxed warning for thyroid tumors and is also approved to lower cardiovascular risk, while Januvia has no boxed warning but no heart-protective approval.

  • Januvia typically costs less per month than Victoza, though out-of-pocket costs depend heavily on insurance coverage.

Januvia vs. Victoza Indications

Januvia

Januvia is FDA-approved to improve blood sugar control in adults with type 2 diabetes when combined with diet and exercise. It works by raising incretin hormone levels, which helps the pancreas release insulin after meals. It is not approved for type 1 diabetes or diabetic ketoacidosis.

  • Improves blood sugar control in adults with type 2 diabetes

  • Used alongside diet and exercise

  • Can be combined with metformin, sulfonylureas, or insulin

  • Not approved for type 1 diabetes or diabetic ketoacidosis

Victoza

Victoza is FDA-approved to improve blood sugar control in adults and children 10 and older with type 2 diabetes, used alongside diet and exercise. It also carries an approval to reduce the risk of major cardiovascular events in adults with type 2 diabetes and established heart disease. Victoza is not approved for type 1 diabetes.

  • Improves blood sugar control in adults and children 10+

  • Used alongside diet and exercise

  • Reduces risk of major cardiovascular events in adults with heart disease

  • Not approved for type 1 diabetes

Januvia vs. Victoza Pros and Cons

Januvia

Januvia offers a simple oral option for blood sugar control without injections, and it has no boxed warning, unlike Victoza. It is generally weight-neutral and usually costs less per month than Victoza. Dose adjustments are needed for people with reduced kidney function.

Pros

  • Oral tablet, no injections required

  • No boxed warning

  • Weight-neutral, does not typically cause weight gain

Cons

  • Not approved to reduce cardiovascular risk

  • Requires dose adjustment based on kidney function

  • Generally produces smaller A1C reductions than GLP-1 drugs like Victoza

Victoza

Victoza is injected once daily and carries a boxed warning for thyroid C-cell tumors seen in animal studies. It is FDA-approved to lower cardiovascular risk in adults with type 2 diabetes and heart disease, a benefit Januvia does not have. Gastrointestinal side effects like nausea and diarrhea are more common with Victoza than with Januvia.

Pros

  • Approved to reduce major cardiovascular events

  • Approved for children 10 and older with type 2 diabetes

  • May produce greater A1C and weight reduction than Januvia

Cons

  • Boxed warning for thyroid C-cell tumors

  • Requires a daily injection

  • Higher rates of nausea, vomiting, and diarrhea
