New Study Links Depo-Provera Contraceptive Injection to Increased Risk of Meningioma Brain Tumors

Certain hormone-based medications, particularly the injectable contraceptive Depo-Provera, may be linked to an elevated risk of developing rare, usually benign brain tumors known as meningiomas. This startling discovery, unveiled in a groundbreaking study recently published in the British Medical Journal, has raised urgent questions about the safety of these widely used treatments. In this article, we will delve into the details of this new study, explore the broader context, and consider the legal and medical implications for affected individuals and the healthcare industry as a whole.

If you or someone you love developed a brain tumor after prolonged use of the contraceptive injection Depo-Provera, we can help. Contact us today to find out whether you may be eligible to file a Depo-Provera lawsuit against Pfizer to pursue compensation for your injuries. 

What are Meningioma Brain Tumors?

Meningiomas are tumors that form in the tissues surrounding the brain and spinal cord. While often non-cancerous, their location can still lead to serious health complications, including changes in vision, hearing loss, memory issues, seizures, and physical weakness. This new research on the use of progestogens and the risk of intracranial meningioma has uncovered a troubling association between certain progestogen medications – a class of drugs that mimic the effects of the natural hormone progesterone – and an increased risk of these brain tumors.

As millions of women worldwide rely on progestogen-based contraceptives and treatments for preventing pregnancy and treating conditions like endometriosis, the implications of this study are profound. It has prompted a flurry of calls for further investigation, as well as renewed scrutiny of the potential risks and benefits of these widely prescribed hormonal medications.

Understanding the Progestogen Study Findings

The landmark BMJ study, conducted by researchers at France’s National Agency for Medicines and Health Products Safety, examined data from over 18,000 women who had undergone surgery to remove intracranial meningiomas between 2009 and 2018. By comparing each case with five healthy, matched controls, the researchers uncovered a startling correlation between prolonged progestogen use and an increased risk of these brain tumors.

Specifically, the study found that women who had used the injectable contraceptive Depo-Provera (medroxyprogesterone acetate) for more than a year were nearly 5.6 times more likely to develop a meningioma that required surgical intervention. Two other progestogen-based medications commonly used for hormone therapy and birth control, medrogestone and promegestone, were also linked to a 4.1- and 2.7-fold greater risk of meningioma, respectively.

Implications for Women Using Depo-Provera, Other Progestogen Medications

These study findings are troubling given the widespread use of Depo-Provera and other progestogen treatments globally. According to the study, as of 2019, approximately 74 million women worldwide were using injectable contraceptives, with usage rates being significantly higher in low-income countries. In the United States alone, nearly one in four sexually active women report having used Depo-Provera in their lifetime, as per a 2023 report by the Centers for Disease Control and Prevention.

Progestogen Medications and Their Uses

Progestogens are a class of synthetic hormones that mimic the effects of the natural hormone progesterone. These medications play a crucial role in various areas of women’s health, including contraception, the management of certain gynecological conditions, and hormone replacement therapy during menopause.

In the realm of contraception, progestogens are a key component of many birth control methods, ranging from oral contraceptive pills to intrauterine devices (IUDs) and injectable formulations like Depo-Provera. These medications work by preventing ovulation and thickening the cervical mucus, effectively blocking sperm from reaching the egg and reducing the risk of pregnancy.

Beyond contraception, progestogens are also widely used to treat a variety of gynecological conditions, such as endometriosis, polycystic ovary syndrome (PCOS), and uterine fibroids. In these cases, the medications help alleviate symptoms, regulate hormonal imbalances, and manage the underlying health issues.

During the menopausal transition and beyond, progestogen-based hormone replacement therapies (HRT) are often prescribed to address the symptoms associated with the decline in natural hormone production, including hot flashes, night sweats, and vaginal dryness.

Lawsuits Alleging Meningioma Risk from Depo-Provera Use

The findings of the BMJ study have already set the stage for a potential wave of legal action, as individuals diagnosed with meningiomas seek recourse for the potential harms caused by progestogen-based medications, particularly the Depo-Provera injectable contraceptive.

In the United States, the manufacturer of Depo-Provera, Pfizer, has already acknowledged the study’s findings and stated that it is “in the process of updating product labels and patient information leaflets with appropriate wording” to reflect the potential risk of meningioma. This admission of a known risk factor could have significant implications for the company’s legal liability.

Attorneys across the country have already begun investigating and accepting cases related to Depo-Provera and other progestogen-based medications linked to meningiomas. These lawsuits may seek compensation for medical expenses, lost wages, pain and suffering, and other damages incurred by affected individuals and their families.
