Zyprexa Breast Cancer Lawsuit Attorneys

If you or a loved one developed breast cancer after taking Zyprexa (olanzapine), you may have the right to compensation. Recent lawsuits allege that Eli Lilly, the manufacturer of Zyprexa, knew about the breast cancer risks but failed to warn patients and doctors. A major lawsuit filed in California in April 2025 accuses the company of concealing evidence linking the medication to breast cancer, putting profits over patient safety. If you were affected, you may need the assistance of Zyprexa breast cancer lawsuit attorneys.

What is Zyprexa?

Zyprexa, also known as Olanzapine, “is an antipsychotic medication that can treat several mental health conditions like schizophrenia and bipolar disorder,” the Cleveland Clinic reports. “It balances the levels of dopamine and serotonin in your brain. These substances help regulate your mood, behaviors, and thoughts.”

Side effects from taking the medication can include allergic reactions, high blood sugar (hyperglycemia), “High fever, stiff muscles, increased sweating, fast or irregular heartbeat, and confusion, which may be signs of neuroleptic malignant syndrome,” infection, low blood pressure, pain or trouble swallowing, seizures, stroke, trouble passing urine, “uncontrolled and repetitive body movements,” or “thoughts of suicide or self-harm, worsening mood, feelings of depression,” the medical center notes.

Specifically, a recognized possible side effect of Zyprexa use is high prolactin level, which can lead to “unexpected breast tissue growth, discharge from the nipple, change in sex drive or performance,” or irregular menstrual cycle, according to the Cleveland Clinic.

Potential Dangerous Zyprexa Side Effects

Zyprexa has long been associated with serious side effects, including significant weight gain and diabetes. However, there is now also evidence that its use may be linked to the development of breast cancer.

In a lawsuit filed in California claiming that Eli Lilly concealed evidence that Zyprexa causes breast cancer, the case cited a study of 540,737 women that found a 54 percent increased breast cancer risk for medium-prolactin drugs like Zyprexa, and a Swedish registry study of over 132,000 women that found a 47 percent increased breast cancer risk after more than five years of exposure to prolactin-increasing antipsychotics such as Zyprexa.

If Eli Lilly withheld critical safety data, leaving thousands of women unknowingly exposed to a life-threatening disease, they should be held accountable with the help of Zyprexa lawsuit lawyers.
