What Is Risperdal and Why Are Lawsuits Emerging?

Risperdal is an atypical antipsychotic medication manufactured by Janssen Pharmaceuticals (a Johnson & Johnson company). It is FDA-approved for schizophrenia, bipolar disorder, and certain behavioral issues, but has also been prescribed off-label for other conditions, including in younger patients.

Risperdal is known to elevate prolactin levels (hyperprolactinemia), a hormone that stimulates breast tissue growth. Prolonged high prolactin has been associated in some studies with increased breast cancer risk, particularly with long-term use of high-prolactin-raising antipsychotics.

Recent lawsuits allege that Johnson & Johnson and Janssen failed to adequately warn patients and doctors about this potential risk, despite known effects on prolactin. The first dedicated breast cancer lawsuits against Risperdal were filed in 2025, with claims continuing into 2026. These are distinct from earlier Risperdal litigation, which primarily involved gynecomastia (male breast growth) and resulted in substantial settlements totaling over $2 billion in government resolutions and hundreds of millions in private gynecomastia cases.

Potential Side Effects Linked to Elevated Prolactin in Women

• Breast cancer (particularly hormone-related cases)
• Hyperprolactinemia (elevated prolactin levels)
• Abnormal breast tissue changes or enlargement
• Galactorrhea (unexplained breast discharge)
• Benign breast tumors (e.g., fibroadenomas)
• Hormonal disruptions, including irregular periods or fertility issues

Note: While hyperprolactinemia is a well-documented effect, the link to breast cancer remains under investigation in ongoing litigation and studies. Some observational research shows elevated risk with long-term use of prolactin-raising antipsychotics (up to 59-62% higher in certain analyses), while other studies have found no short-term increase.

Do You Qualify for a Claim?

You may have a potential case if:

• You took Risperdal (brand or generic risperidone) for any duration.
• You are female (or were assigned female at birth).
• You were diagnosed with breast cancer or related breast conditions after using the medication.
• Your claim is filed within the applicable statute of limitations (in Illinois, this generally starts from the date of diagnosis or when the connection should reasonably have been discovered—consult an attorney for your specific situation).

Eligibility depends on individual medical history, duration of use, and other factors. Many claims require expert review of records. We can help obtain prescription history if needed.

Key Litigation Developments

• 1993: FDA approves Risperdal for schizophrenia.
• Early 2000s: Off-label marketing expands.
• 2006 and later: Studies confirm a strong association with elevated prolactin.
• 2013: Johnson & Johnson pays $2.2 billion to resolve federal investigations into marketing practices and certain side effects (primarily not breast cancer-specific).
• 2015–2021: Thousands of gynecomastia cases resolved, with an additional ~$800 million settlement for many remaining male breast growth claims.
• 2025–Present: New wave of lawsuits alleging Risperdal (and similar drugs like Invega or Zyprexa) contributed to breast cancer via hyperprolactinemia. Cases are active in California and other jurisdictions, with more expected nationwide.

Litigation is still developing. New cases are being reviewed.

What Compensation Might Be Available?

If successful, compensation in product liability cases can include:

• Past and future medical expenses (treatment, surgery, monitoring)
• Lost wages and diminished earning capacity
• Pain and suffering
• Emotional distress
• Other related damages

Amounts vary widely based on the severity of harm, medical evidence, and case specifics. Most pharmaceutical cases settle out of court, though some go to trial.
