Byetta Side Effects

Byetta is an injectable prescription drug used to improve the control of glucose (blood sugar) in patients with Type 2 Diabetes. The medication has also helped some patients with weight loss; however, its primary purpose is to regulate blood sugar as part of a diabetes management regimen. The medication has recently been linked to increased risk of pancreatic, thyroid, or liver cancers. The drug may also cause serious side effects such as pancreatitis and kidney failure.

Patients on Byetta should keep track of potential symptoms of chronic pancreatitis, which could lead to pancreatic cancer. The symptoms include:

  • Abdominal pain
  • Vomiting
  • Fever
  • Nausea
  • Rapid heartbeat
  • Swollen, tender abdomen
  • Changes in bowel movements

The drug manufacturer tried to downplay the medicine’s link to pancreatic cancer, thyroid cancer, and liver cancer; however, following FDA reports, many upper management from the company agreed that cancer could not be ruled out as a side effect.

Other serious side effects of Byetta include:

  • Swelling, weight gain, feeling short of breath, urinating less than usual or not at all;
  • Drowsiness, confusion, mood changes, increased thirst, diarrhea;
  • Dull pain in your middle or lower back;
  • Severe pain in your upper stomach spreading to your back, vomiting; or
  • Low blood sugar (headache, hunger, weakness, sweating, confusion, irritability, dizziness, fast heart rate, or feeling jittery).

Byetta Medical Studies

A preliminary study shows that patients taking Byetta might have an increased risk of developing pancreatitis, pancreatic cancer and thyroid cancer. The study used 2004-2009 information in the U.S. Food and Drug Administration’s (FDA) database to analyze reports on adverse events.

Researchers found that those taking Byetta developed pancreatic cancer 2.95 times as often as those on an unrelated diabetes medication. There is also a six fold increase for patients on Byetta getting pancreatitis when compared to other treatments. They also noted an increase in reported cases of thyroid cancer with Byetta.

In 2007, the FDA reviewed 30 reports of acute pancreatitis in patients taking Byetta. In six patients the symptoms of pancreatitis began or worsened soon after the dose of Byetta was increased from 5 micrograms twice daily to 10 micrograms twice daily. Twenty-one patients were hospitalized. Five patients developed serious complications including dehydration and renal failure. Details in three reports indicated that the symptoms of acute pancreatitis, such as nausea and vomiting and abdominal pain, returned when Byetta was started.

There have also been reports to the FDA of altered kidney function, including acute renal failure and insufficiency. From April 2005 through October 2008, the FDA received 78 cases of altered kidney function (62 cases of acute renal failure and 16 cases of renal insufficiency) in patients using Byetta. Patients reported experiencing the drug’s most common side effects: nausea, vomiting, and diarrhea.

Byetta Lawsuits

Now is the right time to join a Byetta lawsuit. The more people who file, the more likely it is that the cases will get consolidated into Multi-District Litigation (MDL), and the greater the chances are of winning the lawsuit and getting plaintiffs the compensation they are entitled to.

The first lawsuit concerning this drug was filed in 2008 in San Diego Superior Court on behalf of a Virginia man who claims that Byetta’s manufacturer and co-maker Eli Lilly & Co. failed to adequately test and monitor the drug’s side effects. A number of attorneys also say that Amylin Pharmaceuticals and Eli Lilly & Co. have failed to adequately warn about the risks of serious and potentially fatal side effects.

The first lawsuit was filed just two days after the FDA announced it had received six reports of pancreatitis. It is not too late for those patients and their families who have been injured by this drug to file a lawsuit. In fact, the number of lawsuits is expected to skyrocket as awareness about the serious complications attributable to this drug continues to grow.

Anyone who has taken Byetta and sought medical attention for its side effects may be eligible to file a lawsuit. If a patient is in the hospital or has died, their family may be able to file a lawsuit.

Byetta FDA Warnings

In October 2007, the FDA noted 30 reports of acute pancreatitis, a sudden inflammation of the pancreas, in Byetta users. None of those patients had hemorrhagic pancreatitis (inflammation of the pancreas with bleeding) or necrotizing pancreatitis (the inflamed pancreas destroys itself).

On August 18, 2008 the FDA said it planned to strengthen the warnings about life-threatening pancreas problems linked to the type 2 diabetes drug. This action occurred in response to the hospitalization of six Byetta users for pancreatitis. The patients discontinued use of the drug, and two ultimately died.

The FDA warns that patients should halt Byetta injections if pancreatitis is suspected. If pancreatitis is confirmed, do not resume injections unless an alternative etiology for the pancreatitis is identified. Amylin Pharmaceuticals has also had to conduct six post-marketing studies to help further define the mechanism, incidence, and risk factors for the development of acute pancreatitis, as well as explore the drug’s association with the serious risk of thyroid cancer and pancreatic cancer.

There are also reports of kidney failure in patients taking this medication. Due to serious potential consequences of altered kidney function and the development of renal effects from the injection of Byetta, the FDA has approved revisions to the drug’s label detailing this risk for consumers.

The FDA has asked Amylin Pharmaceuticals, the manufacturer of Byetta, to include information about acute pancreatitis in the “Precautions” section of the drug’s label. The FDA has also warned that healthcare providers should remain alert to the signs and symptoms of acute pancreatitis. The symptoms include: persistent severe abdominal pain that can radiate to the back and may be accompanied by nausea and vomiting. Acute pancreatitis is typically confirmed by the presence of elevated levels of serum amylase and/or lipase and characteristic findings by radiological imaging.

On November 2, 2009, the FDA issued an alert to healthcare professionals indicating that changes had been made to the Byetta warning label to include information on reports of kidney problems, such as renal failure and renal insufficiency. See link:

The FDA had 78 patients using Byetta who were experiencing altered kidney function. Of the 78 cases, 62 patients suffered acute renal failure, which is a sudden loss of the kidneys. The remaining 16 patients experienced renal insufficiency, meaning the kidney’s ability to remove waste from the body is lessened.

About Byetta’s Manufacturer

Amylin Pharmaceuticals successfully launched two diabetes medicines, one of which was Byetta, which entered the market upon FDA approval in April 2005, at which point the company began its transformation from a research organization into an integrated biopharmaceutical company with capabilities in research, development, manufacturing, and commercialization.
