Victoza (liraglutide) is considered an injectable incretin mimetic. It is a relatively new drug used to treat type 2 diabetes. It is commonly mistaken with dulaglutide.

It is commonly recommended for adults and children over the age of 10 with type 2 diabetes to be used in conjunction with diet and lifestyle modifications to improve glycaemic control.

Incretin mimetics have been proven to be effective in lowering blood glucose. Clinical research studies have also been shown to be beneficial for weight loss compared to subjects on the placebo when used in combination with diet and exercise.

The FDA first approved Victoza for medical use in adults with type 2 diabetes in 2010 followed by approval in 2019 for the use in children older than ten years with type 2 diabetes. It has become the only non-insulin drug approved by the FDA to be used in the pediatric population since metformin was approved for pediatric use in 2000.

Victoza has been attached to other weight loss medications such as Trulicity and Ozempic.

Please note, Victoza does not replicate insulin vials, pens or cartridges.

Before Taking Victoza

Before taking Victoza, tell your healthcare provider if you:

-have any of the conditions listed in the section “What is the most important information I should know about Victoza?”

-are allergic to liraglutide or any of the other ingredients in Victoza.

-have severe problems with your stomach, such as slowed emptying of your stomach (gastroparesis) or problems with digesting food

Severe Side Effects

Thyroid Tumors

Victoza may cause thyroid tumour including cancer. During the drug testing process, the medicine in Victoza caused rats and mice to develop tumors of the thyroid gland. Some of these tumors were cancers. It is not known if Victoza will cause thyroid tumors or a type of thyroid cancer called medullary thyroid cancer in people. If medullary thyroid cancer occurs, it may lead to death if not detected and treated early. If you develop tumors or cancer of the thyroid, your thyroid may have to be surgically removed.

Before you start taking Victoza, tell your healthcare provider if you or any of your family members have had thyroid cancer, especially medullary thyroid cancer, or Multiple Endocrine Neoplasia syndrome type 2.

Do not take Victoza if you or any of your family members have medullary thyroid cancer, or if you have Multiple Endocrine Neoplasia syndrome type 2. People with these conditions already have a higher chance of developing medullary thyroid cancer in general and should not take Victoza.

While taking Victoza, tell your healthcare provider if you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. These may be symptoms of thyroid cancer.


Victor may also cause inflammation of the pancreas , which may be severe and lead to death. Speak to your healthcare provider if you have a family history fo pancreatitis or are experiencing any symptoms.
