What is Depo-SubQ?

Depo-SubQ Provera 104® is a birth control shot that is sold by Pfizer. The advantage of Depo-SubQ is that women can self-inject it at home every 3 months to prevent pregnancy or treat endometriosis pain.

Depo-SubQ is related to Depo-Provera, which was the original birth control shot when it hit the market in 1992. Both of these medications contain medroxyprogererone acetate, which is now a generic drug.

How Does It Work?

Medroxyprogererone acetate, the active ingredient in Depo-SubQ, is a progestin hormone. Progestins are synthetic versions of a naturally-occurring female sex hormone called progesterone.

Depo-SubQ mimics the effects of the natural progesterone hormone, causing physical changes that reduce the chances of becoming pregnant. Depo-SubQ can also relieve pain due to endometriosis by preventing uterine tissue from spreading to other parts of the body.

In March 2024, a major study linking birth control shots like Depo-SubQ and brain tumors was published in the British Medical Journal. The conclusions of the study were significant because researchers found a 5.6-fold increased risk of brain tumors called meningiomas among women who used medroxyprogererone (the ingredient in Depo-SubQ and Depo-Provera) for at least one year.

What Are Meningiomas?

Meningiomas are the most common type of brain tumor. They are usually slow-growing, non-cancerous (benign), and treatable with surgical removal, but they can be dangerous. Meningiomas can grow very large or come back after treatment. About 10% of meningiomas are atypical or malignant (cancerous).

Where Do They Grow?

Unlike other types of brain tumors, meningiomas do not grow in the brain tissue itself. Instead, they grow out of the membrane layer that surrounds and protects the brain and spinal cord, called the meninges.

Meningiomas are typically found on the surface of the brain, but they can also occur near the brain stem. About 90% are categorized as “benign,” but they can grow quite large and cause health problems like seizures, vision loss, headaches, and other neurological problems.

Meningioma Tumors Can Put Pressure On Brain

As the meningioma grows in size, pressure will increase in the skull. Large tumors can press up against the brain or nearby structures, like blood vessels or sensory nerves involved in sight, hearing, and smell. Some types of meningiomas can block the flow of spinal fluid around the brain and spinal cord, which also increases pressure in the skull.

Signs & Symptoms

There may be no early warning signs or symptoms of a slow-growing meningioma. The tumor can grow for months or years before it is large enough to cause noticeable symptoms, like headaches or seizures.

When the symptoms of a meningioma do appear, they depend on the size of the tumor and where it is located. The symptoms may include:

  • Headache
  • Seizures
  • Vision problems
  • Other neurological problems
  • Nausea and vomiting
  • Hearing loss
  • Loss of sense of smell
  • Problems with balance, walking, or motor skills
  • Weakness or numbness

Why Are Meningiomas So Dangerous?

Meningiomas are usually treatable, but they can be dangerous. About 10% are categorized as atypical or malignant (cancerous). Another problem is that meningiomas can be persistent, likely to return if the tumor is not entirely removed. Unfortunately, it is not always possible to fully remove the tumor without causing more serious symptoms.

Prognosis & Long-Term Outlook

The success-rate and long-term outlook after surgery depends on the size of the tumor, where it was growing, and whether any other structures inside the skull were damaged by the tumor as it grew.

Can I File a Lawsuit?

Depo-SubQ has been sold by Pfizer for years, but women are only recently learning about a potential risk of brain tumors (meningiomas).

There is no excuse for pharmaceutical companies who sell defective medications — especially when they fail to warn women about side effects, or fail to study life-threatening side effects like brain tumors.

Can I Join A Class Action?

Instead of a class action, lawsuits involving people who were injured by defective medications are typically filed as individual lawsuits.

If a large number of lawsuits are filed, judges may centralize the litigation into a federal Multi-District Litigation (MDL). The MDL is a legal process that has many of the same advantages of a class action, such as improving efficiency and cost-effectiveness.

Do I Qualify To File a Lawsuit?

Our law firm is investigating potential lawsuits involving women who used Depo-SubQ before they were diagnosed with a meningioma.

You may qualify to file a lawsuit if you or a loved one:

  • Used brand name Depo-Provera®, Depo-SubQ Provera® or a generic birth control shot called medroxyprogesterone acetate
  • Used Depo-SubQ or another type of birth control shot at least twice before being diagnosed with a brain tumor (meningioma)
