What is Byetta?

An injectable Type 2 diabetes medication that has been linked to side effects like pancreatic cancer, pancreatitis and thyroid cancer.

Byetta (exenatide) is an injectable medication that belongs to a larger class of Type 2 diabetes drugs known as incretin mimetics, or glucagon-like peptide-1 (GLP-1) receptor agonists. Byetta and other GLP-1 receptor agonists are designed to be used in combination with diet and exercise to control blood sugar in patients with Type 2 diabetes, and the drugs function by mimicking the incretin hormones the body normally produces to stimulate the release of insulin in response to a meal. Byetta was approved by the FDA in 2005, and is currently manufactured by drug maker Bristol-Myers Squibb, since the company purchased Amylin Pharmaceuticals in 2012. The Type 2 diabetes medication is packaged in a glass cartridge inside a pen-injector, where the active ingredient, exenatide, is mixed with water and an anti-microbial agent. In addition to Byetta, other popular incretin mimetic drugs prescribed to treat diabetes include Victoza (liraglutide), Januvia (sitagliptin) and Janumet (sitagliptin/metformin).

Possible Side Effects Leading to a Byetta Injury Lawsuit

Once hailed as an incredible advancement in diabetes management, a growing number of studies have shown in recent years that Byetta may be linked to devastating side effects in users, including pancreatitis, pancreatic cancer and thyroid cancer. Pancreatitis is a medical condition characterized by swelling and inflammation of the pancreas that can lead to hospitalization and even death in some cases, with a mortality rate of 10% to 30%. According to research, pancreatitis is a whopping 49-times more common in patients taking Byetta and the newer drug Bydureon, than in patients who take other medications in the same class. Some of the most common symptoms of pancreatitis include:

  • Nausea and vomiting
  • Fever
  • Sweating
  • Severe pain in the upper-left side or middle of the abdomen that worsens after eating or drinking
  • Swollen abdomen
  • Yellowing of the skin
  • Abdominal pain that lasts for several days and may radiate to the back

Pancreatitis is a medical emergency and the condition requires immediate treatment. In some cases, pancreatitis can lead to pancreatic cancer, a cancer that is associated with extremely low long-term survival rates, due to the fact that 80% of cases of pancreatic cancer are diagnosed after tumors have already spread to other organs. Byetta treatment has also been linked to an increased risk of thyroid cancer side effects in some users.

Why We Think Amylin Pharmaceuticals Should Be Held Liable for Byetta Side Effects

In healthy people, eating causes an increase in blood sugar that stimulates an insulin response from the pancreas. In people with Type 2 diabetes, the body is unable to produce enough insulin to react to a rise in blood glucose, and GLP-1 receptor agonists like Byetta are designed to trigger insulin production in order to regulate sugar levels. However, what many diabetic patients don’t realize is that Byetta and other GLP-1 receptor agonists have been linked to a potential increased risk of pancreatitis possibly leading to pancreatic cancer. As a result, former Byetta users across the country are pursuing legal claims against Bristol-Myers Squibb, Eli Lilly and Company, and Amylin Pharmaceuticals, alleging that:

  • The drug companies had a duty to protect the health and safety of patients
  • The drug makers designed, sold and marketed a defective medication
  • The manufacturing companies failed to adequately research the long-term effects of Byetta use
  • The companies failed to warn consumers and doctors about the potential for Byetta to cause pancreatitis, pancreatic cancer and other serious side effects
  • Despite this risk, the drug makers continued to market Byetta as a safe and effective treatment for Type 2 diabetes

What should you do? If you have suffered pancreatitis, pancreatic cancer or another serious side effect, you should contact a lawyer as soon as possible to discuss filing a Byetta lawsuit.

In light of the potential risk of pancreatitis and pancreatic cancer associated with Byetta and similar diabetes medications, close to 600 Byetta, Victoza, Januvia and Janumet lawsuits have been filed in the federal court system, all of which involve similar allegations that the makers of the controversial drugs failed to provide consumers and the medical community with adequate warnings about the possible side effects associated with their products. If you believe you or a loved one has been adversely affected by side effects of Byetta, contact a reputable product liability attorney today for legal help. You may have grounds to file a Byetta lawsuit against Bristol-Myers Squibb, in order to seek fair and timely reimbursement for your losses.
