Victoza

What is Victoza?

Victoza is Novo Nordisk’s once-daily liraglutide injection for type 2 diabetes, and one of the first GLP-1 medications approved, back in 2010. Every newer name in the class builds on the ground it broke.

Today its label covers two things. It is indicated to improve blood sugar in adults and children aged 10 and older with type 2 diabetes, and to reduce the risk of major cardiovascular events in adults who also have established cardiovascular disease.

That second indication is worth reading precisely, because its scope differs from its closest peer’s. Victoza’s requires established cardiovascular disease. Trulicity’s also covers people with multiple cardiovascular risk factors and no established disease. Same class, different reach.

Generic liraglutide also exists, which is unusual in this class, though we do not yet have verified pricing for it or for the brand.

How does Victoza work?

Liraglutide mimics GLP-1, a hormone your gut releases after a meal. Like every drug in the class, it does three things:

1. Quiets appetite signals in the brain, so you feel full sooner.
2. Slows stomach emptying, so meals keep you satisfied longer.
3. Improves insulin response, more insulin when blood sugar is high, less glucagon when it isn’t.

At Victoza’s 1.8 mg diabetes dosing, the insulin effect is the point. The appetite effects are real but noticeably gentler than what Saxenda’s 3 mg dose or the newer weekly molecules deliver.

The daily schedule isn’t a design choice so much as chemistry: liraglutide lasts about 13 hours in the body, versus roughly a week for semaglutide and tirzepatide. The molecule and its relatives are covered in our liraglutide guide and the broader GLP-1 overview.

Victoza and weight loss: what to expect

Victoza is a diabetes medication, and weight is not something it is approved for at any dose.

We are not publishing a weight-loss figure for it. Weight change appears in its trials as a secondary finding, our evidence base carries no verified number, and the figure this page previously showed was flagged as approximate with a visible marker beside it. Reprinting an unsourced number for a drug that is not approved for weight loss would be the wrong call twice over.

What we can say for scale: the same molecule at 3 mg is sold as Saxenda, which does carry the weight-management approval and reached about 7.4 percent against 3.0 percent on placebo in its own trials. The weekly weight-management drugs are further ahead again, around 15 percent for semaglutide and up to 21 percent for tirzepatide in theirs. Those are separate trials rather than head-to-head comparisons.

Come to Victoza for blood sugar and, if you qualify, cardiovascular risk. Not for the scale.

What are the side effects of Victoza?

Mostly digestive, mostly early, and clustered around dose increases. Each rate below is from the adult placebo-controlled trials, shown against the placebo rate in the same trials.

One thing worth stating because it cuts against the class pattern: Victoza’s label carries no diabetic retinopathy warning at all. Trulicity’s does, and semaglutide’s does. There is no class-wide eye warning here, and assuming one would misreport this label.

The label also says Victoza is not recommended in patients with severe gastroparesis, and instructs patients to tell their care team before any procedure requiring general anesthesia or deep sedation. Victoza never carried the suicidality warning; only three products did, and all three had it removed in February 2026.

Practical management, which rests on clinical experience rather than trials of the advice itself: smaller meals, less fatty food and alcohol, and enough fluid. Persistent severe abdominal pain is not a symptom to wait out.

Who should not take Victoza?

Victoza is a fit for most adults with type 2 diabetes, but a couple of conditions make it a hard no, and several more are worth flagging to your prescriber before you start.

The boxed warning drives the absolute contraindications: because liraglutide caused thyroid C-cell tumors in rodents, anyone with a personal or family history of medullary thyroid cancer or MEN 2 shouldn’t take it. Everything in the second column isn’t a stop sign, it’s a reason to make sure your provider has the full picture first.

Victoza dosage: schedule and strengths

Victoza climbs in weekly steps but is injected daily, which is the opposite arrangement from the weekly drugs and the easiest thing to get wrong about it. Per the FDA label:

The 0.6 mg starting dose is deliberately below the treatment range: it exists to let your gut adjust, not to control blood sugar. Many people settle at 1.2 mg, and 1.8 mg is the maximum. Liraglutide goes to 3 mg for weight management, but that is Saxenda’s label, not this one, and the ceilings do not transfer.

Missed a dose? Resume your usual once-daily dose at the next scheduled time, and never double up. If more than 3 days have passed since your last injection, the label directs re-initiation guidance to limit renewed nausea, so check it with your prescriber rather than resuming at your old dose.

How do you use the Victoza pen?

Victoza comes in a prefilled multi-dose pen that holds about two to three weeks of injections, depending on your dose. Unlike the newer auto-injectors, you attach a needle and dial your dose each day.

1. Check the medicine and attach a new needle as your Instructions for Use direct. The label says to use it only if the solution is clear, colorless and free of particles.
2. Dial your prescribed dose of 0.6, 1.2 or 1.8 mg.
3. Inject under the skin of the abdomen, thigh, or upper arm. On Victoza all three are permitted for self-injection, which is not true of the tirzepatide products.
4. Follow your Instructions for Use for the device’s own completion signal; do not carry another pen’s steps across.
5. If you also take insulin, they go in as separate injections, never mixed. Only four labels in this class carry that instruction, and Victoza is one.
6. Remove the needle and put it in a sharps container. Never store the pen with a needle attached, and never share a pen.

Storage follows the label for your product, and in-use windows are presentation-specific across this class rather than a single class rule, so check yours. Any time of day works, with or without meals; consistency matters more than timing.

How much does Victoza cost?

The honest answer: it depends on whether you fill brand or generic. Brand Victoza lists around $815 a month, but as a diabetes medication it’s broadly covered, including by Medicare, so most insured people pay a standard copay. Since 2024, generic liraglutide gives cash payers a lever no other GLP-1 has. Figures below are drafts pending verification, always confirm current pricing.

If you’re paying cash, price the generic with a discount card before filling brand, the spread between pharmacies is large, and a prescription written as “liraglutide” lets the pharmacy dispense whichever is cheaper.

Victoza vs Saxenda, Ozempic, and newer alternatives

The short version: Saxenda is the same molecule wearing a weight-loss label, Ozempic beat Victoza head-to-head on both A1C and weight, and the weekly drugs have largely taken over new prescriptions. Victoza’s case in 2026 is cost and track record, not potency.

How to get Victoza

Victoza is prescription-only, and now that a generic exists, it’s worth asking your prescriber to write “liraglutide” so the pharmacy can fill the cheaper version. Three legitimate paths:

Victoza myths and misconceptions

Victoza has been around long enough to collect its share of confusion. Here’s what’s actually true behind the five claims we hear most.

• Myth Victoza and Saxenda are different drugs.

  They're the same molecule, liraglutide. Saxenda is simply the higher-dose (3 mg) version carrying the weight-loss label; Victoza stops at 1.8 mg for diabetes.

• Myth Victoza is the same as Ozempic.

  No, Victoza is older liraglutide, dosed daily, while Ozempic is semaglutide, dosed weekly. Ozempic beat it head-to-head on both A1C and weight.

• Myth There's no generic version of Victoza.

  Generic liraglutide launched in 2024, the first generic GLP-1, and cash prices often run well below the brand.

• Myth Victoza is mainly a weight-loss drug.

  It's a diabetes drug with proven cardiovascular benefit. Its weight effect is modest, a fraction of the newer weekly options.

• Myth Victoza is a form of insulin.

  It's a GLP-1 receptor agonist that prompts your own pancreas to release insulin when blood sugar is high, a different mechanism, and it doesn't replace insulin.
