Can I Join A Class Action Lawsuit?

If you were diagnosed with a meningioma (or any type of brain tumor) after using at least 2 injections of the Depo-Provera birth control shot, you may be able to file a lawsuit or join a class action against Pfizer.

Depo-Provera Linked to Brain Tumors

In May 2024, Depo-Provera was linked to brain tumors in a study that was published in the British Medical Journal. The researchers found that women who used Depo-Provera for at least 1 year were more likely to develop brain tumors (meningiomas).

What Is My Risk?

The study discovered that women who used Depo-Provera were 5-times more likely to be diagnosed with a brain tumor called a meningioma, compared to women who did not use Depo-Provera.

Progesterone Hormones and Brain Tumors

There are studies dating back to the 1980s showing that meningioma brain tumors are hormone-responsive. About 60% of these tumors have hormone receptors that respond to progesterone, which is the hormone in Depo-Provera, as well as IVF and HRT (Hormone Replacement Therapy). This may help explain why women are far more likely to develop meningiomas than men.

What Is A Meningioma?

A meningioma is a brain tumor that starts in the meninges, which is a protective membrane layer that covers the brain and spinal cord.

About 90% of meningiomas are slow-growing and non-cancerous, and because these tumors are usually located on the surface of the brain, most meningiomas are treatable with surgery to remove the tumor.

Nurse Diagnosed With Meningioma After Depo-Provera

In July 2024, the New York Post highlighted the story of a nurse who was diagnosed with a brain tumor the size of a golf-ball after taking Depo-Provera and other hormone medications with progesterone, like IVF and HRT.

She underwent a major surgery to remove the tumor, which was growing near her optical nerve and could have caused blindness. The surgery was successful, but she still suffers from memory loss.

Depo-Provera Class Action Lawsuits for Bone Loss

Our law firm is only accepting cases involving brain tumors from Depo-Provera, Depo-SubQ, and birth control shots. However, in the past, Pfizer ended up paying a $2.2 million settlement in a Depo-Provera class action in Canada for women with bone mineral density loss.

In the U.S., this earlier litigation also involved several Depo-Provera lawsuits for bone loss. This litigation has been resolved and lawyers are not filing new lawsuits for this type of injury. In 2007, judges handed Pfizer a victory and refused to centralize Depo-Provera lawsuits for bone loss.

Class Action Plaintiffs Seek Payout for Medical Care

One of these earlier lawsuits for Depo-Provera was a class action that was seeking medical monitoring for women who used Depo-Provera and were at risk of osteoporosis. This lawsuit was Lorenzi v. Pfizer Inc.. This type of “medical monitoring” class action was filed by one woman on behalf of a much larger group of other women with similar health issues. Unfortunately, this Depo-Provera class action did not end with Pfizer paying for medical monitoring.

$2.2 Million Depo-Provera Class Action Settlement

In September 2021, Pfizer agreed to pay a $2.2 million Depo-Provera class action settlement for women in Canada who experienced bone mineral density loss. The class action settlement only applied to women in Canada who used Depo-Provera before May 31, 2010 and suffered bone mineral density loss, osteopenia, or osteoporosis. (However, our Depo-Provera lawyers are only accepting cases involving brain tumors).

About Class Action Lawsuits

The label on Depo-Provera now carries a “Black Box” warning about bone mineral density loss — but no warnings about brain tumors. Our lawyers are concerned that Pfizer may have failed to adequately warn women about the risk of brain tumors, failed to adequately study this side effect, or update the warning labels on Depo-Provera.

What Happens As The Tumor Grows?

Meningiomas are not usually cancerous tumors, but they can still cause serious health problems — especially if they grow quite large. The growing tumor can push against the brain and cause seizures, headaches, memory loss, and other neurological problems. The tumor can also damage blood vessels, block the flow of spinal fluid to the brain, or damage sensory nerves involved in sight, smell, or hearing.

What Symptoms Can Meningiomas Cause?

The symptoms of a meningioma depend on the size of the tumor and where it is located. The symptoms may be vague (such as dull headaches that are worse in the morning) and get worse over time.

Not all meningiomas cause symptoms. These brain tumors can grow slowly for years without causing any symptoms at all. In fact, many people are surprised to be diagnosed with a meningioma when they undergo a CT scan or MRI for a head injury. The symptoms of a meningioma may include:

Vision problems
Headaches
Seizures
Other neurological problems
Memory loss
Loss of smell
Trouble speaking
And more
