Approved by the Food and Drug Administration (FDA) in 1996, Zyprexa (generic olanzapine), made by Eli Lilly Co., was introduced as an antipsychotic medication to treat the serious disorders of schizophrenia and bipolar disorder. Although the drug helped patients with these mental disorders by reducing or eliminating the side effects of other antipsychotic drugs through its chemical composition, Zyprexa became associated with potentially worse side effects that included hyperglycemia, ketoacidosis, diabetes type II, and pancreatitis.

Seven years after the drug’s introduction, the FDA stipulated that a warning label be added to alert consumers and healthcare professionals about the side effects associated with Zyprexa.

Zyprexa Side Effects

If you are taking Zyprexa and are experiencing negative effects, you should contact your doctor immediately. Some of the most common side effects of Zyprexa are:

  • Agitation
  • Personality changes
  • Constipation
  • Dizziness
  • Dry mouth
  • Increased appetite
  • Indigestion
  • Sleepiness
  • Weight gain
  • Tremors or weakness

History of Warnings about Zyprexa

A possible link between Zyprexa and hyperglycemia in youngsters was first reported in November 2001 by medical officers from the FDA’s Center for Drug Evaluation and Research and a Duke University Medical Center physician. Those reports hastened the path to warn the public further about Zyprexa.

FDA staff members published a report in the American Journal of Medicine about the link between Zyprexa and diabetes, pinpointing 384 cases of diabetes after Zyprexa use. These cases typically occurred about six months after the patient began using Zyprexa.

Consequently, the Japanese Ministry of Health, Labor and Welfare and the British equivalent of the FDA issued warnings about Zyprexa after reports of serious hyperglycemia and diabetes surfaced.
