Seroquel is a popular drug approved to treat schizophrenia and bipolar disorder. Seroquel belongs to a group of medications called atypical antipsychotic medications. This group also includes Zyprexa, Geodon, Risperdal, and Clozari. Seroquel users face an increased risk of many side effects including diabetes. Diabetes symptoms may include:

  • Frequent urination
  • Excessive thirst
  • Extreme hunger
  • Unusual weight loss
  • Increased fatigue
  • Irritability
  • Blurry vision

What is Diabetes?

Diabetes is a disease where the body does not produce or properly use

insulin. Insulin is needed to convert sugar into energy. Scientists do not know what actually causes diabetes, however, evidence shows that genetics and obesity play a major role in developing diabetes. In the United States, an estimated 24 million people have diabetes. Unfortunately, about 6.2 million people, representing 25% of diabetic patients, have not been diagnosed and are unaware that they have diabetes.

There are two main types of diabetes:

  • Type 1: Type 1 diabetes is the more severe and less common diabetes form. An estimated 5 to 10% of Americans who are diagnosed with diabetes have Type 1. Type 1 diabetes results from the body’s complete failure to produce insulin. Insulin injections are necessary for survival.
  • Type 2: Most Americans with diabetes are diagnosed with Type 2. Type 2 diabetes results from the body’s inability to properly use insulin. Typically, Type 2 diabetes is treated with diet and exercise.

Seroquel Linked to Diabetes

In August 2003, the Wall Street Journal reported that a study linked Seroquel use to diabetes. The study analyzed about 20,000 U.S. war veterans between October 1998 and October 2001. The study concluded that veterans who used atypical antipsychotic medications, like Seroquel, were at a higher risk for developing diabetes. The increased risk was greater for Seroquel users than for the other atypical antipsychotic medications.

On August 23, 2003, a Seroquel study’s results were reported at the International Society for Pharmacoepidemiology conference in Philadelphia. The Seroquel study showed that patients using Seroquel had 3.34 times more cases of diabetes compared to older antipsychotic drugs.

Does Seroquel Cause Diabetes?

Scientists are unsure if Seroquel causes diabetes, however, experts maintain that reports indicating a link between Seroquel and diabetes cannot be ignored. Some experts speculate that Seroquel causes diabetes because Seroquel is known to cause weight gain and weight gain is a contributive factor to developing diabetes.
