Research shows that Lipitor, a medication used to treat high cholesterol, can raise blood sugar levels in patients and lead to type 2 diabetes.

Lipitor (atorvastatin), a cholesterol medication made by Pfizer, Inc., is the bestselling drug of all time, with $130 billion in sales.

It belongs to a group of drugs known as statins, which lower cholesterol production in the liver. Lipitor has helped many patients to manage cardiovascular risks such as heart disease, heart attack, and stroke, but research shows that Lipitor can also raise blood sugar levels and lead to type 2 diabetes.

A new warning label for this side effect was added to Lipitor in 2012, but many believe that the warning came too late and is insufficient.

As a result, thousands of Lipitor patients who developed type 2 diabetes have filed lawsuits against Pfizer alleging that the company should have included stronger warnings on Lipitor labels.

About Pfizer

New_York_City_Pfizer_World_Headquarters_02Founded in 1849 and headquartered in New York City, Pfizer is the pharmaceutical giant behind Viagra (sildenafil), the anti-inflammatory Celebrex/Celebra, and the antibiotic Zithromax, among countless other drugs. Pfizer is famous for swallowing up smaller drug companies, including Warner-Lambert, Pharmacia, and Wyeth (which was a $68 billion acquisition).

Pfizer has faced numerous lawsuits over the years, both from its drugs’ side effects and its business practices. In 2009, the company paid $2.3 billion to the government to settle a case over its unlawful marketing of the arthritis drug Bextra—a charge to which Pfizer pled guilty. In 2016, Pfizer paid $486 million to settle a shareholder lawsuit alleging the company caused financial losses when they covered up the safety risks of taking Celebrex and Bextra.

A Brief History of Lipitor

A team of scientists led by chemist Bruce Roth synthesized atorvastatin in August 1985 at the Parke-Davis Pharmaceutical Research facility in Ann Arbor, Michigan. After ten years of tests and trials, the FDA approved the drug (under the product name Lipitor) in 1996.

From 1996 to 2011, Lipitor grew into one of the most popular drugs of all time—one prescribed to 30 million people seeking to lower their cholesterol. At its peak, Lipitor made Pfizer $10 billion per month.

But in November 2011, Pfizer’s Lipitor patent expired, opening the market up to a wide range of (cheaper) generic competitors. Lipitor’s profits have steadily declined since then, but still total roughly $2 billion a month, and the drug’s forecast remains strong.

Pfizer did not warn patients of Lipitor’s adverse effects until 16 years after it hit the market.

The drug’s bullish outlook is somewhat surprising given its alleged side effects, which include an increased risk of type 2 diabetes, memory loss, and confusion. Even more surprising, Pfizer did not warn patients of these adverse effects until 2012: 16 years after Lipitor hit the market.

In 2014, Pfizer explored an over-the-counter version of Lipitor, but was forced to abandon the product when patients proved unable to administer the drug without a doctor’s guidance.

In 2014 and 2015, Lipitor’s lack of adequate warnings from 1996 to 2012 spawned thousands of lawsuits from patients who developed diabetes.

At present, roughly 3,000 cases are part of an MDL (multidistrict litigation) concerning Lipitor’s side effects. Most of the plaintiffs are female; studies suggest Lipitor is more likely to cause diabetes in women (see below: “Lipitor and Type 2 Diabetes”). The first of these trials should be heard sometime in 2016.

Lipitor and Type 2 Diabetes

Researchers don’t know exactly how statins can lead to diabetes. One theory is that statins can increase a patient’s insulin resistance. Another is that statins impair the ability of the pancreas to secrete insulin.

In the body, food is broken down into sugar (glucose), which travels through the bloodstream. In a normal patient, the pancreas will release insulin in response to a meal to reduce blood sugar levels and allow glucose to enter the body’s cells, providing them with the energy needed to function.

But patients with type 2 diabetes cannot produce enough insulin, or cannot use the insulin efficiently enough. As a result, glucose cannot enter the body’s cells and instead builds up in the blood, causing a spike in blood sugar levels. High levels of sugar in the blood can result in a number of serious health problems, including organ damage and heart attack.

Researchers suspect that Lipitor can inhibit the function of the pancreatic cells responsible for storing and releasing insulin, and may also decrease the body’s sensitivity to the hormone.

Research suggests that statin therapies such as Lipitor increase the risk of type 2 diabetes by 46%.

Though it isn’t perfectly understood how Lipitor increases diabetes risk, the association is well established in medical literature, including studies published in BMJ, Journal of the American College of Cardiology, Journal of General Internal Medicine, Diabetologia, and JAMA.

Many studies have found that statins increase the risk for diabetes by 10-25%, but newer research suggests that statin therapies such as Lipitor increase the risk of type 2 diabetes by 46%.

Another analysis found that statin drug users were 87% more likely to develop diabetes. (This study is significant because it was the first to look at the link in relatively healthy patients.) The study also found that patients on statins were 250% more likely to develop diabetes with complications compared to non-statin users.

Some evidence suggests that statin-associated diabetes may be more common in women.

Type 2 diabetes is a lifelong condition that can be managed, but not cured.

Did Pfizer Properly Warn About the Lipitor Diabetes Risk?

The FDA approved a new Lipitor warning label in 2012: 16 years after it hit the market. Many believe this was too little, too late, and that the new warning does not clearly present the diabetes risk.

Under “Endocrine Function” warnings and precautions, Lipitor prescribing information now reads, “Increases in HbA1c and fasting serum glucose levels have been reported with HMG-CoA reductase inhibitors, including LIPITOR.”

Patients have argued (justifiably) that they do not understand that this warning relates to diabetes risk, and that a more explicit Lipitor diabetes warning is needed.

Thousands of Lawsuits Filed Against Pfizer

The FDA’s 2012 announcement about Lipitor and diabetes prompted lawsuits alleging that Pfizer did not properly warn consumers about the diabetes risk.

Lipitor lawsuits now number above 3,000, making it one of the largest product liability lawsuits in the country. Lipitor cases are consolidated in South Carolina District Court as part of a multidistrict litigation (MDL). The first lawsuits are expected to be tried in 2016 and should offer insight into whether Pfizer will offer a Lipitor settlement.

It is not too late to join the ranks of those seeking compensation from Pfizer. If you took Lipitor and developed type 2 diabetes, you may qualify for a lawsuit.

Patients who develop diabetes from Lipitor will live with the condition for the rest of their lives. Diabetics must undergo regular blood glucose testing, follow a strict diet, and take medication. They are also at an increased risk for disabling and life-threatening complications:

  • Cardiovascular disease
  • Nerve damage
  • Kidney damage
  • Alzheimer’s disease

A lawsuit can compensate victims for all their medical bills (including future medical bills) related to their diabetes, as well as for lost wages or reduced earning power resulting from the disease. Lawsuit compensation may also cover things like physical pain, mental anguish, and reduced quality of life.
