| Key Takeaways Victoza (liraglutide) is a once-daily injection for type 2 diabetes, not insulin. Doctors start at 0.6 mg and slowly raise the dose to ease nausea. A generic version is now approved in India and needs a prescription. |
If you have been prescribed Victoza, or you are weighing your options for managing type 2 diabetes, understanding how this medicine works can help you feel more in control.
This guide walks through what Victoza does, how it is dosed, what side effects to watch for, and where it stands in India today.
1. What Is Victoza, and Is It the Same as Insulin?
Victoza is the brand name for liraglutide, a medicine known as a GLP-1 receptor agonist. It is not insulin.
GLP-1 (glucagon-like peptide-1) is a natural gut hormone your body releases after eating. Victoza copies its action.
It tells the pancreas to release more insulin when blood sugar is high, lowers a hormone called glucagon, and slows how quickly the stomach empties. Together, these effects help steady blood sugar and curb appetite.
The U.S. Food and Drug Administration first approved liraglutide in 2010 for type 2 diabetes. It is given as a small injection under the skin once a day.
So if you have read that “Victoza is insulin,” that is a common mix-up. Insulin replaces a hormone your body cannot make enough of, while Victoza helps your body use its own insulin more effectively.
Ask your doctor how Victoza fits alongside any other diabetes medicines you take, since the two can sometimes be used together.
2. What Is Victoza Actually Used For?
Victoza is approved mainly to improve blood sugar control in people with type 2 diabetes, used together with a healthy diet and regular movement.
According to the FDA prescribing information, it is approved for adults and for children aged 10 years and older with type 2 diabetes. It is meant as an add-on to lifestyle changes, not a replacement for them.
Victoza is also approved to lower the risk of major heart problems, such as heart attack and stroke, in adults who have type 2 diabetes along with known heart disease.
If weight is part of why you are considering Victoza, talk with a qualified healthcare professional about whether liraglutide, or another option, suits your goals and health history.
3. How Do You Use Victoza? Your Step-by-Step Dosing Chart
Victoza is taken as one injection under the skin (subcutaneously) once a day. You can take it at any time of day, with or without food, but try to keep it around the same time daily.
The injection sites are the abdomen, the front of the thigh, or the upper arm. Rotating the site each day helps protect the skin.
Doctors raise the dose slowly. This step-up approach, called titration, is designed to reduce stomach-related side effects like nausea.
The starting dose of 0.6 mg is used for the first week only. As noted in the FDA label, this dose is meant to ease your body in and is not strong enough to control blood sugar on its own.
Typical Victoza dosing schedule
| Stage | Dose | Duration | Purpose |
|---|---|---|---|
| Week 1 (start) | 0.6 mg once daily | 7 days | Ease in, reduce nausea (not for glucose control) |
| Step up | 1.2 mg once daily | Ongoing | First maintenance dose for blood sugar |
If needed | 1.8 mg once daily | Ongoing | Maximum dose for added glucose control |
The dose moves up in 0.6 mg steps, with at least one week between increases. Most people settle at 1.2 mg or 1.8 mg once daily.
Victoza comes in a pre-filled pen. It is used with fine, short pen needles, and many people use a 32-gauge needle for comfort. Your pharmacist can show you the right needle to pair with the pen.
Missed a dose? The FDA guidance is simple: take your next dose at the usual time and do not double up. If more than 3 days have passed, your doctor may restart you at 0.6 mg to settle your stomach again.
If you are unsure how to inject, ask your care team to walk you through it once. A short demonstration removes most of the worry.
4. What Does the Research Say About Victoza?
Victoza is one of the better-studied diabetes injections, with large trials behind it.
The landmark LEADER trial, published in the New England Journal of Medicine in 2016, followed 9,340 adults with type 2 diabetes and high heart risk for a median of 3.8 years.
In that study, major heart events (heart attack, stroke, or heart-related death) occurred in 13.0% of people taking liraglutide compared with 14.9% on placebo. Deaths from heart causes also fell, from 6.0% to 4.7%.
A linked analysis of kidney outcomes, also in the New England Journal of Medicine, found fewer new or worsening kidney problems with liraglutide than with placebo.
On weight, the SCALE research program tested the higher 3.0 mg dose of liraglutide (sold as Saxenda) and reported an average weight reduction of about 8% over 56 weeks, versus roughly 2.6% with placebo.
Keep in mind that these weight results come from the 3.0 mg dose, which is higher than the 1.8 mg ceiling for Victoza. Results at the Victoza dose may be more modest.
What this means for you: the strongest evidence supports Victoza as a tool for blood sugar control and, in the right patients, heart protection.
Your doctor can explain how these findings apply to your situation.
5. What Are the Side Effects of Victoza?
Most Victoza side effects involve the stomach and tend to fade as your body adjusts.
The most common ones are nausea, diarrhea, vomiting, constipation, headache, and indigestion. Nausea is most noticeable in the early weeks, while the dose is being raised.
Eating smaller meals, stopping before you feel full, and avoiding very greasy food can take the edge off the nausea for many people.
Victoza side effects at a glance
| Type | What you may notice | What helps |
|---|---|---|
| Common | Nausea, diarrhea, vomiting, constipation, headache, indigestion | Smaller meals; usually eases within weeks |
| Less common | Low blood sugar (mainly with insulin or sulfonylureas) | Know the signs; doctor may adjust other medicines |
| Rare but serious | Pancreas inflammation, gallbladder problems, allergic reactions, kidney strain from dehydration | Seek prompt medical care; stop and call your doctor |
Victoza also carries a boxed warning, the FDA’s most serious label notice. In animal studies, liraglutide caused thyroid tumours, though it is not known whether this happens in people.
Because of this, Victoza should not be used by anyone with a personal or family history of medullary thyroid cancer or a condition called MEN 2. Share your full family history with your doctor.
Get medical help quickly if you have severe stomach pain that will not go away, signs of an allergic reaction, or symptoms of very low blood sugar.
6. Victoza vs Ozempic: How Do They Compare?
Victoza and Ozempic belong to the same family of medicines, but they are not identical. Both are GLP-1 receptor agonists.
The main practical differences are the active ingredient and how often you inject. Victoza is liraglutide, taken once a day. Ozempic is semaglutide, taken once a week.
In the head-to-head SUSTAIN-10 trial, weekly semaglutide lowered long-term blood sugar (HbA1c) and body weight more than daily liraglutide 1.2 mg.
A separate weight-loss trial, STEP 8, in the Journal of the American Medical Association, found greater weight loss with semaglutide than with liraglutide.
Victoza vs Ozempic at a glance
| Feature | Victoza | Ozempic |
|---|---|---|
| Active ingredient | Liraglutide | Semaglutide |
| How often | Once daily | Once weekly |
| Drug class | GLP-1 receptor agonist | GLP-1 receptor agonist |
| Main approved use | Type 2 diabetes; heart-risk reduction | Type 2 diabetes; heart-risk reduction |
| Trial-based weight effect | Effective; generally less than semaglutide | Greater average weight loss in head-to-head data |
Neither is simply “better” for everyone. The right choice depends on your blood sugar targets, how you feel about daily versus weekly injections, side effects, and availability.
7. Is Victoza Available in India?
Liraglutide is available in India, and access has been widening.
In June 2025, India’s drug regulator, the Central Drugs Standard Control Organisation (CDSCO), approved a generic version of liraglutide made by Biocon.
It was cleared for type 2 diabetes in adults, adolescents, and children aged 10 and older, as an add-on to diet and exercise.
This approval came through the CDSCO’s newer 101 route, which recognises approvals already granted by trusted regulators abroad. It marked one of the first locally made GLP-1 injections of its kind in India.
Liraglutide is a prescription-only medicine in India. That means you cannot buy it over the counter; a registered doctor must prescribe it after assessing whether it is right for you.
If you are exploring liraglutide, the safest first step is a consultation with your physician or an endocrinologist. They can confirm availability of a specific brand or generic and guide you on safe, genuine sources.
The Bottom Line
Victoza (liraglutide) is a once-daily injection that helps control type 2 diabetes and, in some people, lowers heart risk. It is not insulin, and the higher-dose Saxenda is the version approved for weight loss.
Doses start low and rise slowly to limit nausea. With a generic now approved by India’s CDSCO, talk with your doctor about whether Victoza fits your treatment plan.
