Victoza is a medication created by Novo Nordisk that is primarily prescribed for diabetes management but has recently become a useful tool for weight loss.

Dosing and administering Victoza is extremely convenient and simple as it comes in a prefilled pen simplifies the process for users. This article aims to provide a detailed understanding of how to use Victoza effectively, ensuring safe and proper dosing practices. 

This article provides information on various aspects of Victoza, including frequency of dosing, usage, and safety measures. This is not medical advice, and you should always follow the directions and recommendations provided by your prescriber.


What is Victoza?

If you live with type 2 diabetes, your doctor may prescribe Victoza. Victoza isn’t used for type 1 diabetes. This drug is used to:

  • Manage blood sugar in adults and some children, along with a healthy diet and exercise
  • Decrease the risk of severe cardiovascular events in adults who also have heart disease

Victoza is a solution that you’ll inject under your skin using a pen. It belongs to a group of diabetes drugs called glucagon-like peptide-1 (GLP-1) receptor agonists. Other drugs in this family include Wegovy, Ozempic, and Mounjaro. Victoza is not currently available as a generic.

Victoza may help adults lose some weight. In clinical studies of adults with type 2 diabetes, ranging from 26 to 52 weeks in length, many lost some weight. In a large study, when Victoza was added to metformin, adults lost, on average, up to 6.2 pounds.

Decoding Victoza Dosage


In this section, we’ll discuss everything you need to know about Victoza dosing. As mentioned above, following your medical provider’s dosing and administration instructions is important. Do not make any changes to your dose without consulting with your doctor. Altering the prescribed dose without medical advice can have serious consequences.

Victoza dosing is not a one-size-fits-all approach. It is based on several variables, including the medication's strength, the specific medical condition being addressed, and the patient's age. 

  • Type 2 Diabetes Mellitus Injection: Initiate with a 0.6 mg dose, with adjustments made as per individual needs to effectively manage blood sugar levels
  • Heart Attack/Stroke Prevention: Commence with a 0.6 mg dose, with subsequent adjustments as required for personalized preventive care against heart attacks and strokes
  • Obesity Treatment: For adults seeking obesity treatment, the recommended starting dose is 0.6 mg, with weekly increments up to a maximum of 3 mg. It's essential to note that this dosage adjustment is suitable for adults only, and Victoza is not indicated for children in obesity treatment

Victoza Administration Guidelines

There are specific guidelines for the proper administration of Victoza, which helps ensure the safety of users and maximizes the benefits of this diabetes management medication. It's important to follow the guidelines diligently to achieve the best results and to ensure your overall well-being. 

Guidelines for Correctly Using Victoza

  • Vary Injection Site: Inject under the skin of your stomach (abdomen), thigh, or upper arm. Do not inject Victoza into a muscle or vein. Change your injection site within the area you choose with each injection to reduce your risk of getting lumps under the skin. Do not use the same site for each injection
  • Daily Administration: Take Victoza daily, ensuring it is separate from meals to enhance effectiveness. Avoid doubling doses, as this can lead to unintended consequences
  • Gradual Dosage Increase: Begin with a 0.6 mg dose for the first week, providing a gentle introduction to the medication. Subsequently, increase the dosage to 1.2 mg for continued blood sugar control or as otherwise directed by your prescriber
  • Consider 1.8 mg for Enhanced Control: Depending on individual needs, a healthcare provider may recommend a dosage of 1.8 mg for extra blood sugar control.
  • Missed Dose Protocol: If you miss a dose of Victoza, take the same amount the following day to maintain consistency in your treatment plan. Don’t double your dose, as it may increase the risk of low blood sugar
  • Extended Gap Between Doses: If three or more days pass since your last Victoza dose, consult a healthcare professional promptly. They can provide guidance on how to resume the medication safely

Potential Side Effects: What You Need to Know


While Victoza is FDA-approved and generally recognized as safe for most individuals, there are potential side effects of Victoza you should be aware of. This allows you to make informed decisions about your treatment.

Whether you experience side effects of a drug can depend on:

  • Age
  • Comorbid health conditions
  • Other prescription drugs or medications

Your doctor or pharmacist can tell you more about the potential side effects of Victoza. They can also suggest ways to help reduce side effects.

Here are some mild side effects that some people taking Victoza may experience:

  • Nausea/Upset Stomach: Some people taking Victoza may experience either mild or severe nausea. Your doctor may prescribe other medication to manage this side effect
  • Constipation: Because GLP-1 receptor agonists cause delayed gastric emptying, some users may experience constipation as a side effect. Maintaining a well-balanced diet, eating high-fiber and probiotic-rich foods, and staying adequately hydrated can help manage this symptom
  • Diarrhea: On the other end of the spectrum, diarrhea may occur in some individuals. Monitoring dietary habits and consulting with a healthcare provider or dietitian can help manage this side effect
  • Lowered Appetite: Victoza's impact on appetite may vary among users. While some may experience a reduced appetite, others may not notice a significant change. This can be a positive aspect for those aiming for weight loss
  • Headache: Headaches are a common side effect that may occur during the initial stages of Victoza use. Staying hydrated and ensuring a consistent dosing schedule may help alleviate this symptom.
  • Injection Site Reactions: Users may encounter mild reactions at the injection site, such as redness or irritation. Proper injection techniques and rotating injection sites can minimize these effects.

Mild side effects of most drugs typically resolve within a few days to a couple of weeks. If they are persistent and become bothersome, talk with your doctor or pharmacist.

Serious Side Effects

Sometimes, serious side effects from taking Victoza can occur, but they aren’t common. If you experience these serious side effects from Victoza, you should immediately call your doctor or seek emergency medical attention. 

Serious side effects of Victoza that have been reported include:

  • Pancreatitis (inflammation of the pancreas)
  • Severely low blood sugar levels
  • Gallbladder disease
  • Kidney failure
  • Risk of medullary thyroid cancer (MTC)
  • Allergic reaction
  • Angioedema

These are some common, uncommon, and rare side effects of taking Victoza. Always consult with your healthcare provider to discuss any concerns or adverse reactions promptly.

Victoza's Important Safety Measures

Using Victoza pens requires attention to safety measures to ensure the medication's effectiveness and the user’s safety. Follow these tips for securely handling and storing Victoza pens to safeguard your health throughout the treatment process.

  • Store the Victoza pen in a clean, dry place, shielded from direct sunlight and excessive heat. Consistent adherence to suitable storage conditions preserves the integrity of the medication
  • If you have a new, unused Victoza pen, store it in the refrigerator between 36 and 46°F. If refrigeration is not feasible, use the pen within 30 days or discard it
  • After first use, the pen can be stored at room temperature (59 to 86°F), or keep it in the fridge. Dispose of the pen if it has been exposed to temperatures exceeding 86°F, as this may alter the medication's effectiveness
  • After each use, promptly remove the needle from the Victoza pen and recap it to prevent accidental needle sticks and maintain hygiene
  • Regardless of whether the pen is fully used or not, you should discard a Victoza pen after 30 days for safe use and the prevention of potential complications
