A study conducted by the Journal of the American College of Cardiology in 2011 indicated patients taking Lipitor (atorvastatin) had an increased risk of developing type 2 diabetes mellitus. The study compiled results of three large randomized clinical trials and found throughout all trials that patients taking a higher dosage (80mg) of Lipitor reported higher incidents of the development of type 2 diabetes.

Factors associated with Lipitor use and the development of type 2 diabetes include gender and body mass index. The Centers for Disease Control and Prevention define the body mass index as a number calculated from a person’s height and weight that is used to screen for weight categories that may lead to health problems. The following is a chart provided by the CDC for body mass index and weight status.


Weight Status

Below 18.5


18.5 – 24.9


25.0 – 29.9


30.0 and Above



Numerous clinical trials have been conducted and have indicated that women taking Lipitor–or other statin drugs– who have a body mass index of 25 or less, have an increased risk for developing type 2 diabetes mellitus .

The U.S. Food and Drug Administration (FDA) issued a safety notice in February 2012 requiring a label change for Lipitor and other statin drugs to include an increased risk for the development of type 2 diabetes. This notice was given after the FDA completed a comprehensive review statin drugs along with adverse event reports.

Women who have taken Lipitor and have developed type 2 diabetes have filed complaints against Pfizer, the maker of Lipitor.
