Victoza (liraglutide) is a once-daily, injectable mediation. It helps adults with Type-2 diabetes control their blood sugar (glucose) levels. Victoza is manufactured and sold by Novo Nordisk, a Danish drug company, and it was approved in the United States by the FDA in 2010. Victoza must be used along with diet and exercise, and it should only be used when other medications fail to adequately control blood-sugar levels.

When a person has Type-2 diabetes, they have chronic metabolic problems controlling their blood sugar levels after they eat a meal. When Victoza is injected, it treats this problem by mimicking the action of a hormone called GLP-1, which stimulates the pancreas to produce extra insulin. Insulin tells cells to absorb more sugar from the bloodstream.

Allergic Reactions

If you took Victoza and suffered a serious allergic reaction, you are not alone. Though rare, serious allergic reactions to Victoza do occur in some people. During an allergic reaction, the immune system (a defensive system that protects us from harmful foreign invaders) accidentally identifies a substance as harmful. The immune system creates antibodies to these invaders which are specifically designed to identify and attack the invader. An allergic reaction is an over-reaction of the immune system to substances that are actually harmless.

There were five safety studies of Victoza which lasted for 26 weeks. During this time, approximately 2% of Victoza patients developed injection site allergic reactions. These reactions typically involved rashes and erythema at the injection site. Of all people taking Victoza, 0.02% stopped taking Victoza because they had a severe allergic reaction.

When the body has an allergic reaction to a substance, it creates antibodies designed to attack the substance. Clinical trials found that 8.6% of Victoza patients tested positive to antibodies to Victoza. However, since only 50-70% of people in the trial were tested for antibodies, the real number may be far greater. The problem is that 6.9% of these people had antibodies that also accidentally attacked native GLP-1 (the natural hormone that Victoza is designed to mimic). Researchers called this finding “clinically significant,” because it is possible that Victoza neutralizes the effectiveness of GLP-1 for an unknown period of time. The risk was not assessed fully during trials.

Allergic reactions linked to Victoza include:

  • Injection site reactions
  • Erythmia
  • Hives (also known as “urticaria”)
  • Upper respiratory tract infections
  • Gastrointestinal problems

Symptoms of a Victoza Allergic Reaction

The symptoms of a Victoza allergic reaction vary widely, with some people suffering minor itching, while others may have severe, life-threatening allergic reaction that requires emergency medical attention. The Medical Guide to Victoza lists all the ingredients, and people who might be allergic to these ingredients should talk to a doctor before taking Victoza.

Symptoms of an allergic reaction may include:

  • Swelling (face, tongue, throat, or lips — in severe cases, swelling may interfere with breathing
  • Fainting, dizziness, drowsiness
  • Fast heartbeat
  • Difficulty breathing, swallowing
  • Skin rash (hives, redness, etc.)
  • Itching

Public Advocacy Group Calls for Ban of Victoza

In April 2012 the advocacy group Public Citizen petitioned the FDA to ban Victoza immediately. The group cited numerous safety concerns, which suggest that the risk of this medication outweigh any benefit. With 11 other classes of diabetes drugs already on the market, some experts feel that there is no risk for the public to risk their health and safety with a new drug that has already been linked to severe side effects.
